HP 34401a DMM with leaking segments

iMo:
Any idea what is the filament current of the original display?
Thanks.
coromonadalix:
10 ohms of impedance / resistance
iMo:
Ok, 10ohm, and the voltage is 6V (when looking into the SM p.9-7) therefore 600mA AC, imho.
coromonadalix:
6v in 10 ohms is 600ma not 60 ma
iMo:
That is a long back I saw something like 600mA :)

A pretty large current, my display is normally off (I use BT), so I think I will switch the filament off as well.. Another project..
