CALIBRATION PROCEDURE
Calibration parameters are logically divided into groups
of two parameters each – initial scale value and final
scale value. A calibration check is provided after entering
the values of each group. It is also possible to perform a
calibration check without making an entry: press the
FUNC button twice when “OFF” is displayed. The instru-
ment goes directly to the group check.
Before beginning calibration, be sure the internal DIP
switch V101 is open.
WARNING: Perform the calibration procedure according
to J106 jumper positions as shown in Figure 1. Other-
wise, the stored calibration values may be lost.

General Guidelines
a) The instrument should be mounted in its case in order
to keep the internal temperature constant.
b) Ambient temperature should be stable. Avoid drift due
to air conditioning or other mechanical devices.
c) Relative humidity should not exceed 70%.
d) Minimum warm up time of at least 20 minutes.
e) Operate as much as possible in a noise free
environment.
f) during calibration, connect one input at a time to the
rear terminal block.
g) Use calibrators with the following:
Accuracy
TC Input: +0.005% output
+0.001% range
+5 mV
RTD Input: +0.02%
+0.0025 Ω decade
CJ Compensation: better than 0.1°C
Current Transformer: 0.1 mA AC rms
Resolution
TC Input: 1 mV
RTD Input: 10 mΩ
