PowerPod-400 Power Supply/Totalizer

All procedures outlined in this document must be performed with the power supply turned on and warmed up for at least one hour.

All procedures outlined in this document must be performed with NO transducers connected to the channel being adjusted*.

You CANNOT successfully zero a channel without, first, supplying zero volts or four milliamps to the meter input for that channel.

You CANNOT successfully span a channel without, first, supplying the meter input for that channel with its appropriate span voltage or span current.

14.1 Zeroing Unit (Voltage Range).

The following instructions explain how to short a given channel’s input signal to ground (0 volts DC) and set the display to read zero at this voltage.

Locate the 15-pin, ‘D’ type connector that corresponds to the channel to be zeroed. J1 = Channel 1

J2 = Channel 2

J3 = Channel 3

J4 = Channel 4

Short pin 5 (signal common) to pin 6 (signal in).

Press MODE

Press 3

Press ENTER

Press 1, 2, 3 or 4, depending on which channel is to be zeroed.

Press ENTER

Press 7

Press ENTER

Press 1
