2. Convert the Model 1140A’s error from microvolts to degrees Celsius. For a Type E
thermocouple, the conversion is:
Error in °C = (error in µV) × 0.0164°C/µV.
3. Negate the polarity of the error to produce the correction amount. For example, if the
DMM reads 1.3 µV above the expected value, the correction is –0.021°C.
4. Add the correction from Step 3 to the value displayed on the screen and enter the
result as the new correction. Digits up to the thousandths place may be entered.
5. Press ENTER and verify that the reading on the DMM has changed by the desired
amount.
Repeat this section using the thermocouple connector instead of binding posts. If a correction is
needed, select THERMOCOUPLE CONNECTOR CORRECTION in Step 1.
