Figure 6-3: Setup for Calibrating Current Outputs

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:

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:
044100102 Rev A

Operating Instructions
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.
ENTR returns
to the previous
menu.
EXIT ignores the
new setting, ENTR
accepts the new
setting.
