Helios PD2-6400 High Voltage & High Current Meter 

Instruction Manual

Setup and Programming 

There is 

no need to recalibrate

 the meter when first received from the factory. 

The meter is 

factory calibrated

 prior to shipment for amps and volts with 

calibration equipment that is certified to NIST standards. 

Overview 

The only switch to set on the meter is the AC/DC switch located at the back of the instrument next to the screw 
terminal connectors. See 

Current and Voltage Input

 on page 

17

 for further details. 

Setup and programming is done using MeterView Pro or through the programming buttons. 

After power and input signal connections have been completed and verified, apply power to the meter.
