Update for spreadsheet

Keithley 196 which I recently acquired has ZBXO math functions . The meter table shows it has nothing . This is a true sleeper meter in my opinion. LED display is awesome. Takes 2 hours to stabilize to full specs per manual. Current and ACV is 5.5 digits max (which is not typical for 6.5 digit meters) but has excellent low current ranges 300uA , 3mA, 30mA, 300mA, 3A!

Also has ohms compensation which is not common . Too bad it has no statistical functions as it would be perfect. Also can be front panel calibrated and saves to EEPROM . Each range can be re calibrated separately.

The HP 3457A has MAND not MND . Average (Actually called MEAN on the HP) displays 8 digits and exponent not sure how many samples can be used but have used recently with 41.3k samples when i stopped the stats function.
