TIA:
Push "blue" key then "blue R" ( the shifted "TRIG" key) and "ENTER".
Then press the downarrow "V" key 4 times to get to the "REV?" on the
display. Then press "ENTER" and two numbers will be displayed with a comma
in the middle. The first number is the multimeter's master processor
firmware revision. The second number is the slave processor's firmware
revision. This is if the "full menu" has been set. If not, see the "MENU"
command in the Operator's Manual and set it to "FULL".
Mine are both "7,2" and I have no problems. The latest is "9".
