Section 3 Calibration
3.1 Calibration
Units with serial numbers beginning with the
letter N use the calibration procedure outlined
below. Older units do not display version
numbers and use the calibration procedures
on page 19 .
The calibration procedure should be performed
by a qualified instrumentation service technician.
The indicator may be brought to any instrumentation
calibration and repair laboratory (metrology lab) for
the service (this manual should accompany the
instrument). This procedure should be done at least
once a year to guarantee continued performance
within the specification.
The instrument should be calibrated at an ambient
temperature of 22° C with a thermocouple simulator
