Internal Source Calibration (ICAL)
The meter is factory calibrated prior to ship-
ment to read in milliamps and volts depend-
ing on the input selection. The calibration
equipment is certified to NIST standards.
The internal source allows the user to scale the meter without applying
a signal.
The use of calibrated signal sources is necessary to perform the internal
source calibration of the meter.
Check calibration of the meter at least every 12 months. Each input
must be recalibrated separately.
Notes:
1. If meter is in operation and it is intended to
accept only one input type (e.g. 4-20 mA),
recalibration of other input is not necessary.
2. Allow the meter to warm up for at least
15 minutes before performing the internal
source calibration procedure.
The Internal calibration menu is part of the Advanced Features menu.
1. Press and hold the Menu button for three seconds to access the
advanced features of the meter.
2. Press the Up arrow button to scroll to the Internal calibration menu
(ICAL) and press Enter.
3. The meter displays either current calibration (C CAL) or voltage
calibration (v CAL), according to the input setup. Press Enter to
start the calibration process.
