Calibration Section
Input Calibration
Use this procedure to calibrate the selected input range.
1. Turn off CJC.
2.
Select your Input Type and click the “Send Config” button.
3. Click on the Calibration-
Input “Instructions” button.
4.
Click on the “Zero” button.
5. Input the required voltage displayed in the pop-up box and click
“OK”.
6.
Click on the “Full Scale” button.
7. Input the required voltage displayed in the pop-
up box and click “OK”.
8. Repeat steps 2-6 until all required input ranges have been calibrated.
Note that some ranges are calibrated coincidentally. For example, Type
K and Type N are calibrated by calibrating Type J. Type R and Type S
are calibrated by calibrating by calibrating Type T.

Output Calibration
Use this procedure to calibrate the 4-20mA output range endpoints
1. Turn off CJC.
2.
Select your Input Type and click the “Send Config” button.
3. Click on the Calibration-
Output “Instructions” button.
4.
Click on the “Zero” button.
5. Input the required voltage displayed in the pop-
up box and click “OK”.
6. C
lick on the “Full Scale” button.
7. Input the required voltage displayed in the pop-
up box and click “OK”.
Tref Calibration
Use this procedure to calibrate the cold junction compensation.
1. First, calibrate the TC Type J input range as shown above.
2. Connect a TC Type J ice point reference to the device input terminals.
3.
Click on the “Tref-Cal” button.
4. In the pop-
up box, click “OK”.

Calibration
If your output appears
imprecise, you may need to
repeat calibration, but being
very careful to take accurate
measurements and to input
the correct signal levels. If
measuring voltage across the
output load resistance, make
sure that you use the exact
input resistance when
calculating the current
measured. Also, make sure
that you have an adequate
input span, as too-tight input
spans have diminished
resolution and may magnify
error.
