Figure 0-3: Setup for Calibrating Current Outputs
CAUTION
Do not exceed 60 V between current loop outputs and instrument ground.
To adjust the zero and span values of the current outputs, press SETUP-MORE-DIAG-ENTR-
NEXT-NEXT and then:

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:
