Charge Pump Output Check/Verify ?
« on: July 15, 2008, 10:23:38 AM »
Hey Folks,
Using a DMM, can the Mach Charge Pump freq. be checked... or just verified on its assigned port/output pin ?
Not the actual pulse count, just positive evidence of its presence.
Thanks,
RC

I would imagine if you put the DMM on mv range you should see something, cant test as a boats skipper just borrowed the DDM but when he brings it back I will test it if you havent had an answer from any one else.

OK just got the meter back, getting 2+ volts at the chargepump, thought it would be less but forgot its not a high frequency . So yes you should get a voltage of around 2 or 3 volts.
