3.16 – Operating with a Digital Volt/Amp Meter
The DVAM (Digital Volt/Amp Meter) 3100A provides measurements for all voltage ranges and amperage
draws between zero and 2,000. The DVAM 31000A indicates the aircraft or vehicle’s current demand.
Integrated with the Tesla™ Turbo Start™ GPU power supply, the DVAM is a valuable tool for troubleshooting
and system checks.
The left meter indicates DC voltage output and the right meter indicates amperage draw. The meter’s range
changes from 0-200 AMPS to 0-2,000 AMPS with the flip of a switch. The 200 amp setting provides a more
detailed reading extending to two decimal places. The 2,000 amp setting reads higher currents such as
engine starts and in rush currents.
