Internal calibration (ICAL)
Note
• The meter is factory calibrated prior to shipment, for all input types, in milliamps, volts and
degrees respectively.
• The calibration equipment is certified to NIST standards.
The internal calibration allows the user to scale the meter without applying a signal. This
menu is not available if the meter is set up for TC or RTD inputs.
The use of calibrated signal sources is necessary to perform the internal calibration of the
meter.
Check calibration of the meter at least every 12 months. Each input type must be
recalibrated separately, if meter will be used with all input types.
Note
• If meter is in operation and it is intended to accept only one input type (such as 4 to 20
mA), recalibration of other inputs is not necessary.
• Allow the meter to warm up for at least 15 minutes before performing the internal
calibration procedure.
