Analog Channels: DC Amperage Measurement 

 

The

 

DC

‐

RMCU1

 

comes

 

pre

‐

configured

 

from

 

the

 

factory

 

to

 

measure

 

amperage

 

on

 

channel

 

1.

 

A

 

jumper

 

is

 

installed

 

on

 

the

 

board

 

in

 

the

 

channel

 

1

 

circuit

 

to

 

configure

 

it

 

to

 

measure

 

+/

V

 

max

 

instead

 

of

 

+/

‐ 

100

 

V

 

max

 

to

 

measure

 

the

 

low

 

voltage

 

associated

 

with

 

the

 

meter

 

shunt.

 

DC

‐

RMCU1

 

Channel

 

1

 

is

 

calibrated

 

to

 

use

 

the

 

100

50mV

 

shunt

 

supplied

 

with

 

the

 

DC

‐

RMCU1.
