FAQ’s2023-09-22T19:53:31+00:00
My scan window in DARWin isn’t updating when I take a new scan, why?2023-09-22T19:58:31+00:00

When viewing the scan in DARWinTM, right click on the spectrum and there should be a checkmark next to “active”. If “active” is not checked off, then the window isn’t activated to update with each new scan. Select “active” and take a new scan and it will display the data. If you follow the menu path for “Window” at the top of the screen, the last option on the menu will display all open windows within DARWinTM and you can alternate between which plots you are viewing; you may want some windows to be active and others to be inactive, so they do not change.

I’m trying to compare multiple scans in DARWin, but it only shows my most recent scan, how do I view multiple?2023-09-22T19:58:14+00:00

To view multiple scans in the same window for comparison you would want to open a “new multiple measurement” plot. This can be done by right clicking on the spectrum and selecting from the menu for “Send scan data to” and click on “New Multiple Measurement Plot”. The other option is by clicking on the button for “New Plot” in the header tools and selecting “New Multiple Measurement Plot”, or by going to the menu path for “Window”, hovering over the first option for “New Plot” and selecting from the drop-down for “Multiple Measurement”.

Which foreoptic am I supposed to choose in DARWinTM?2023-09-22T19:57:53+00:00

There is a drop-down list of Optic options in DARWinTM. DARWinTM comes loaded with presets for optic settings, these are all the options above the option for NONE. Select the appropriate option for your optic (which probe you’re using) and the software has been designed to optimize the data from their output. If you ordered accessories with your instrument, then they would appear underneath the optic option for NONE. These are the optics that have been calibrated with your instrument and selecting these options will load those calibrations. This is especially important if trying to measure direct energy – you need to choose the calibrated optic for that calibration to load into DARWinTM. The options labeled as FIBER15 or FIBER20 are for your fiber optic cable and the numbers indicate the length (example 15 is for 1.5 meter fiber)

Should I be using DARWin SP or DARWin LT?2023-09-22T19:57:36+00:00

DARWinTM SP is designed to run on a PC or laptop. DARWinTM LT has been specifically designed to run on the rugged field tablet Spectral Evolutions sells. If you’re on a laptop or PC be sure to be running DARWinTM SP and if you’re on the field tablet, be sure to run DARWinTM LT.

Can I open an old scan in DARWin?2023-09-22T19:57:14+00:00

Yes, there is a menu path at the top of the DARWinTM user interface screen for “File”. Click on this menu path and the first option under it is “Open Stored Data File(s)”. This will allow you to search through your documents and open the scans you wish to view. You can open one scan in a “single measurement” plot in DARWinTM or you have the option to select many scans and open them a “multiple measurement” plot for direct data comparison.

Why are there two scan files that save (.RAW and .SED)?2023-09-22T19:56:53+00:00

If there is ever an issue with your data we request that you email our customer service department with the .SED and .RAW files.

How do I remove my Fiber Optic Cable from the accessory?2023-09-22T19:07:38+00:00

To remove the Fiber Optic Cable from an accessory with the quick release silver metal button, simply loosen the mounting screw and press the quick release button. The fiber will pop out of place. For accessories with the screw on SMA-905 mount, simply unscrew the SMA-905 threaded end from the accessory port and remove the fiber.

How do I connect my Fiber Optic Cable to the accessory?2023-09-22T19:07:20+00:00

The Fiber Optic cable can be attached to our accessories in two different ways. Some accessories, like the contact probe and pistol grip, require the use of the ferrule on the end of the Fiber Optic Cable. The cable is inserted into the SMA Fiber Port, the flat side on the ferrule is lined up with the flat side in the port, and the quick release silver square metal button should be depressed. Then the fiber can be pushed into the port fully and the button can be released. This will lock the fiber in place. You should be able to give it a little pull and it won’t move. For additional stabilization some accessories with this connection method will also have a mounting screw on the side where the fiber gets inserted to tighten and hold the fiber securely in place. Other accessories, like the leaf clip and R/T Sphere, only require you to screw the threaded SMA-905 connector end of the Fiber Optic Cable onto the SMA Fiber Connection Port on the accessory.

Can I change the lightbulb in my accessory?2023-09-22T19:07:03+00:00

Yes, our accessories have user replaceable light bulbs, and we sell replacement bulbs for our accessories. Contact our customer service team for a quote on replacement bulbs and directions on performing the change out.

Do my accessories need to warm up?2023-09-22T19:06:46+00:00

Accessories that have an integrated light source should be warmed up for about 5 minutes prior to use, this will allow for the bulb to reach full temperature and provide scans that don’t show drift over time.

What is the white plate that came with my instrument for?2023-09-22T19:06:25+00:00

The white plate is a reference for Reflectance Measurements. The target scan you take will be directly compared within the DARWinTM program to the white reference and provide you the reflectance of the sample. If your conditions remain the same and the sample remains the same, you wouldn’t need to take a white reference for every target scan. However, anytime a condition changes you want to be sure to take a new reference scan – this will keep your reference and target scan as close as possible condition wise and keep your data as accurate as possible.

When I press the trigger on my accessory it isn’t taking a scan, what do I do?2023-09-22T19:06:04+00:00

You want to be sure the accessory has the Accessory Power Cable connected fully, that the red dots line up on the cable and the port, and there is an audible click is heard. If this cable is properly connected, be sure you have turned the accessory switch on. The trigger will not work if there isn’t power to the accessory, and it is turned on. Finally, check that the External Trigger Feature has been enabled in DARWinTM. You should have clicked on the “EXT TRIG START” button and would now see it reflect a red stop sign that says, “EXT TRIG STOP” (show photo and double check the red stop sign thing). The trigger will not properly initialize a scan if this feature hasn’t been turned on. If you’re still experiencing issues, please contact our customer service team for assistance!

The light on my contact probe isn’t working anymore, what happened?2023-09-22T19:05:39+00:00

There are two lights on the contact probe, there is a red LED light on the power switch of the contact probe and there is a built-in 5-Watt Tungsten-Halogen lightbulb within the probe. When the contact probe is plugged into the spectrometer via the accessory power cable and the power switch is switched to the ON position, the red LED light will illuminate on the power switch itself. If this red LED light is on you know power is being supplied to the contact probe. The next light that turns on is the built-in light. If you put your hand in front of the window of the contact probe, or move it close to a surface, you will see the light source illuminated. The Tungsten-Halogen bulb has a long lifetime; however, they still burn out. If this is the light that isn’t working, it is user replaceable, and Spectral Evolutions sells replacement bulbs. Please contact our customer service team for a quote and directions on how to perform this replacement.

How often should I replace my batteries?2023-09-22T19:05:14+00:00

The Lithium-Ion Batteries are long lasting but do require replacement over time. With each year of use the batteries do begin to lose their ability to hold a charge, for this reason Spectral Evolution recommends replacing your batteries about every four years to maintain the longevity of them and continue getting accurate data by providing enough power to your instrument. Please contact our customer service team for a quote on new batteries!

How many batteries does the instrument come with?2023-09-22T19:04:54+00:00

The instruments that have been designed for field use come with one battery. The instruments that have been designed for use in the lab come with a Wall Power Supply cable and no batteries. Additional batteries can be purchased for lab or field instruments. Please contact our customer service team if you would like a quote on additional batteries!

How long do the batteries last in the field?2023-09-22T19:04:27+00:00

The batteries Spectral Evolution provide are high-capacity Lithium-Ion batteries and should offer at least 4-5 hours in the field. This time frame does depend on how much power is being drawn from the batteries; for example, if you’re using an accessory with a light source or trigger that will draw more power than a bare fiber. Please contact Spectral Evolution for a quote on additional batteries if you are planning an extended field campaign!

Where can I find my scan files?2023-09-06T18:34:32+00:00

The scan files are saved automatically to a folder within your Documents entitled Spectral Evolution. Subfolders will be created for the model and serial number specific to the instrument being used and then another subfolder titled as the date the scans were taken. Find the scans in these subfolders and open the .SED file within DARWinTM to view the spectrum or within notepad or Microsoft Wordpad to view the ASCII style document. If you want to change where the scan file saves to, that option exists in the Instrument Control Panel in DARWinTM.

Is it required that I use DARWinTM to operate the instrument?2023-09-06T18:27:00+00:00

Yes, our instruments and our DARWinTM program are designed to go hand in hand. They need each other to function properly. The scan data is saved in an ASCII style format for easy exporting and post processing if required.

Can I use the instrument while it is plugged into a wall outlet?2023-09-06T18:26:24+00:00

If the instrument is plugged into a Wall Power Supply and then a wall outlet, then yes it can be operated using power from the outlet. If the battery is charging, the instrument cannot be operated using the power that comes from the wall while charging the battery.

Can I take stand-off measurement as well as contact measurements?2023-09-06T18:25:51+00:00

Yes you can! Using the bare fiber, the fiber with a lens, or the fiber and the pistol grip holder you can take stand-off measurements of your target. Using the leaf clip, benchtop reflectance probe, or contact probe you can take contact measurements of your sample.

Can I initiate a reference scan using the trigger button on my accessory?2023-09-06T18:24:20+00:00

Reference scans cannot be initiated using the trigger button on accessories, it must be initiated within the DARWinTM program by clicking on the “REF” button. The only exception to this is when using the SensaprobeTM with our RS-8800 instrument.

Can I be provided with training on my instrument?2023-09-06T18:23:12+00:00

Absolutely! Spectral Evolution is pleased to offer in-person training or virtual training. Please contact the sales team for a quote!

How do I initiate a scan?2023-09-06T18:20:45+00:00

Scans can be initiated within the DARWinTM program. A reference scan can be initiated by clicking on the “REF” button whereas a target scan can be initiated by clicking on the “SCAN” button. If you have an accessory connected to the instrument with a trigger capability, you can initiate a target scan using the trigger button. In DARWinTM click on the “EXT TRIG START” button which will enable the external trigger feature, then click the trigger button on the accessory – do not hold it down. Continue to remain steady in either your contact to the sample or your position to the sample in a stand-off measurement. The trigger button initiates the scan, but it still takes a couple seconds for the instrument to gather all the data and output the scan. Wait until the data has finished being collected by the instrument and DARWinTM indicates the scan is complete before moving.

How do I connect to the instrument via Bluetooth?2023-09-06T18:14:57+00:00
