Press SET> to select the analog output channel
to be configured:.
Increase or decrease the current
output by 100, 10 or 1 counts.
The resulting change in output
voltage is displayed in the upper
line.
Continue adjustments until the
correct current is measured with
the current meter.

If a current meter is not available, an alternative method for calibrating the current loop outputs is
to connect a 250 Ω ±1% resistor across the current loop output. Using a voltmeter, connected
across the resistor, follow the procedure above but adjust the output to the following values:

6.9.4.6. AIN Calibration
This is the sub-menu to conduct the analog input calibration. This calibration should only be
necessary after major repair such as a replacement of CPU, motherboard or power supplies.
Activate the ANALOG I/O CONFIGURATION MENU (see Section 6.9.1), then press:
