Calibrate Analog Output
Use the ACAL command to calibrate the currently active analog output
mode. You must use this command if you change the analog output mode
using the AMODE command.
ACAL
After you give this command, the analog output of the module is set to
the low limit of the selected output (voltage or current). Measure the
output and enter the measured value. After entering the low limit, you
must measure and enter the high limit also.
Example (analog output in 4 ... 20 mA mode):
>acal
I1 (mA) ? 3.981
I2 (mA) ? 20.002
2.00985160E+03 a0
1.12789450E+03 a1
0.00000000E+00 a2
OK

Example (analog output in 0 ... 1 V mode):
>acal
V1 (V) ? 0
V2 (V) ? 0.998
5.45999950E+02 a0
1.64128260E+03 a1
0.00000000E+00 a2
OK
