TC Measure Calibration Adjustment

The Product begins the adjustment with a prompt to connect to a vdc calibrator.
1. Connect the Type B copper mini-plug with copper wire between a calibrator and the Product TC
INPUT/OUTPUT. Allow 3 minutes for thermal dissipation.
2. Tap Continue.
3. Follow the on-screen instructions to apply the specific amplitude to the Product.
4. Wait for the calibrator to settle and tap Continue.
5. Follow the on-screen instructions until all steps that require calibrator output are complete.
6. When prompted, connect a characterized Type J thermocouple to the Product.
7. The characterized thermocouple should be immersed in a lag bath together with the thermistor
probe monitored by a thermometer (thermometer system).
8. Both the thermocouple and the probe have to be immersed to the same depth and be in close
proximity.
9. Obtain calibration data for the characterized thermocouple Type J in error from nominal near
ambient - tcerror.
10. Take a measurement with the thermometer system - Thermometer
11. Calculate the Thermometry System output as:
Standard temperature = Thermometer
12. When prompted by the Product, input the calculated standard temperature. The display prompts for
Abort or Save. Tap Save.
This concludes the calibration adjustment of the Product.
Maintenance
This section explains how to perform the routine maintenance and calibration task required to keep a
normally-operating Calibrator in service.
To prevent possible electrical shock, fire, or personal injury:
