0 … 20 mA

4 … 20 mA

0 … 5 V

0 … 10 V

LED alarm

Current alarm

Voltage alarm

Example:

amode 1 2

Ch1 output : 0 ... 20 mA

Ch2 output : 4 ... 20 mA

Calibrate Analog Output

Use the ACAL command to adjust analog output channels.

ACAL [channel]<cr>

where

channel

Analog output channel to be adjusted, 1 or 2.

After entering the ACAL command, use a calibrated current/voltage

meter to measure the output, and enter the values.

Example:

acal 1

Ch1 U1 ( V ) ? 1.001

Ch1 U2 ( V ) ? 9.011

acal 2

Ch2 U1 ( V ) ? 0.0988

Ch2 U2 ( V ) ? 0.8997
