To view current calibration point, see Section 6.8 - Viewing Calibration .
Do not reuse calibration solutions after calibration. Contaminants in the solution can
affect the calibration, and eventually the accuracy of the measurements. Use fresh
calibration solution each time you calibrate your meter.
NOTE:
Your transmitter is factory set to a temperature coefficient of 2.1% per
°
C.
For most applications this will provide good results. The factory default value
for normalization temperature is 25
°
C. If you need to set a different
temperature coefficient or change the normalization temperature value, see
Section 6.5 - Temperature Coefficient and Normalization Temperature
Setting for further information.
NOTE:
In the CAL mode, the 4/20 mA output current will be automatically held.
‘HOLD’ will be displayed on LCD. After calibration is performed and when the
transmitter is back to the measurement mode, the ‘HOLD’ is automatically released.
Please refer to section 6.3 for more details.
