A major benefit of buying LabMax is its ability to be easily upgraded by owners. As new firmware is released all LabMax power and energy meters can be updated to incorporate the latest features and bug fixes.
We have designed the updater to automatically recognize the hardware version in the meter so you do not have to keep track of it. The firmware updater will automatically install all features supported by the hardware level in your meter.
Firmware Upgrade Installation Instructions
1. Download the LabMax_V3.5.zip file at the bottom of this web page to your computer.
2. Double click the LabMax-V3.5.zip file to open the unzip utility on your computer. Read the ReadMe.txt file and then extract the file 'LM-Updt-v3.5.tar.gz' to the root directory of a USB flash drive. (Note: Do not extract the files within the actual LM-Updt-v3.5.tar.gz file itself.)
3. Plug LabMax into an AC power source and then turn the meter ON.
***Do not use battery power when installing a firmware update. A power loss during the installation process will damage the meter, which must then be returned to Coherent for repair.***
4. Connect the flash drive to the USB flash drive connector on the side panel of LabMax.
5. When the menu appears on the LCD, turn the Selection knob to highlight the firmware name and then press the Enter/Set button (Selection knob) to begin the installation.
6. When prompted on the installation menu, remove the flash drive and press the Exit soft key to reboot LabMax.
7. Delete the 'LM-Updt-v3.5.tar.gz' file from the USB flash drive.
