ADC-100 Meter not working

Postby BrianDSmith » Wed Dec 04, 2002 8:41 pm


The adapter fixes the problem. Thanks.

I still cannot get the voltmeter to diplay any DC volts. The scope display shows a proper DC voltage is present. The AC voltmeter has the same problem. The scope display shows an AC voltage but the voltmeter display show zero volts.

Any help is appreciated.

The meter can be very slow at responding to voltage changes as it has to scan multiple input ranges and timebases to find the most suitable one. When a scope window is running at a timebase less than 100ms/div, it does tie up a lot of resources which can have this adverse effect on the meter.

The way around this issue is to use the scope measurements, choose Settings|Measurements|Add and select DC volts. This measurement will then appear at the bottom of your scope trace.
