1594A/1595A Firmware update version 1.22

Title: 1594A & 1595A
Ver: 1.22/1.02
Use with: All 1594A & 1595A
Date Modified: 2/20/2014

Description of the change: 
It was recently determined that when a customer selects the “Restore Factory Default” button in the Config Menu, the resistor calibration values are reset to the default values without requiring a password or notification to the customer that the values are being reset. Engineering has investigated this issue and the instrument firmware has been revised to ensure that the resistor calibration values are not reset to the default values. A password is now required to access the Restore Factory Default capability of the instrument.
Fluke is willing to upgrade your instrument with new firmware at no cost to you. There are three options with regards to upgrading instruments depending on the instrument firmware version. We have verified that upgrading the firmware does not affect the calibration.
