Procedure for calibration of TC Measure
To enter into the TC Measure Calibration, Select the
TC
option in
Calibration page and MEASURE TC option in CAL. TC page.
All Thermocouple and mV input are divided into 3 groups.
For Better Calibration Accuracy group 3 is divided into two sub ranges.
So for these group, Calibration of both sub ranges need to done. The
Sub Ranges of each input type is given in the below table.
TC MEASURE Group
Sub Range
Recommended Zero
Recommended Span
1
-10 to 80 mV
1
-5.000 mV
20.000 mV
2
S -TC
1
35.000 mV
75.000 mV
3
-10 to 250 mV
1
95.00 mV
125.00 mV
2
126.00 mV
235.00 mV
Note:
It is not compulsory to calibrate at recommended points. User can
calibrate at any points within specified Sub Range. The Sub Range is
shown on the screen. But make sure to calibrate Zero & Span in the
same sub range.
Example: - Calibrating Group-1
Select Group 1 in TC Group ListBox.
To calibrate
ZERO for Sub Range #1,
Apply mV Input value near to Recommended Zero Value for Sub
Range 1 (for Group 1 sub range 1 it is -5.000mV) from reliable source
device.
For example, If apply -5.000mV from the external source.
Measured
value shows the value that has been measured by the UC-12. If this
value is -5.030 enter -5.000 value in
ZERO Actual Value
