How is the software for the DR3900 updated?
DR3900 Software Update Procedure
After downloading the DR3900 Spectrophotometer Software Update - V1.27 28 14, the DR3900 can be updated using the following procedure: 

1. Unzip the "" file. There will be a software revision number after the DR 3900. Do not further unzip the "dr3900.tar.gz" file.
2. Copy the file "dr3900.tar.gz" to the root folder of a blank USB memory stick.
3. Connect the memory stick to the USB interface of the DR 3900 and navigate to the main menu of the instrument.
4. Select "System Checks" in the lower left corner of the main menu, then select "Instrument Update". Select "OK".

5. Wait until the update has been completed. This takes several minutes.
6. After update completes, shut down the DR3900, wait 10 seconds and restart.

Verify the update was successful by navigating from the main menu to “System Checks” then “Instrument Information”. The instrument version should show the correct version that was just updated.

If the instrument update fails, verify that the USB stick is recognized by the meter by navigating from the main menu, select "Instrument Setup", then "PC & Printer". If the USB memory stick is recognized, the DR 3900 should state "USB Memory: Connected". If the instrument says "Not Connected" at this point, try a different USB memory stick, reformat the USB stick as FAT32, or ensure the steps above are correct.
