Helios PD2-6262 Dual Analog Input Rate/Totalizer

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 milliamps and volts with

calibration equipment that is certified to NIST standards.

Overview

There are no jumpers to set for the meter input selection.

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.
