New firmware update for Fluke 1663 and 1664FC Installation Testers, which introduces the 6mA RDC-DD testing functionality for Electric Vehicle (EV) charging stations.
Important Note: Please read the following instructions carefully before proceeding with the update. Ensure that your Fluke tester is either a model 1663 or 1664FC. This firmware update is not applicable to Fluke 1662 or previous installation tester modules.
Check the current firmware version of your Fluke tester by following these steps:
Whilst pressing ‘F1’ power on the tester, releasing ‘F1’ after >3s. The firmware version shows when you release ‘F1’.
- Press and hold the F1 button
- While holding F1, press the power button to turn on the tester
- The screen will display two numbers on the screen
If your firmware version is 1.10/1.10 or above, your Fluke 1663 or 1664FC already has the 6mA test functionality, and you do not need to proceed with the update.
If your tester has an earlier firmware version, please check the appropriate option below based on the unit Serial Number to get the unit updated (to find the unit's Serial Number, press the power button and the memory button simultaneously. The primary display will show the initial Serial Number four digits):
a) Instruments (1663 and 1664FC) manufactured from Jan 2023 (starting from SN 6053xxxx ): No update necessary, as the 6mA function is already included in the unit.
