Calibration

Page 131

Recalibration is carried out in five phases as shown in the table below; each phase 
corresponds to a basic input type.

Table 27. Input Calibration phases

DC milli-volt Calibration

50 mV



10 V

20 mA

RTD Calibration

200 ohm

Thermocouple Calibration

K type source at 0ºC

1. For optimum accuracy, power-up the instrument for 30 minutes, then toggle the power 

off/on to restart the instrument.

2. During the power-up “splash screen”, press 



and 



together until the Calibration 

Status screen is displayed.

3. Press 



to select the first calibration phase (50mV Calibration)

4. Ensure that an accurate 50mV signal has been applied to terminals 2 (+ve) and 3 (-ve), 

then press 



+ 



to initiate the calibration.

5. During calibration the message “50mV DC Input Calibrating” will display for a few 

seconds. This should be followed by the “Calibration Successful” confirmation.

6. If the input is misconnected or an incorrect signal is applied, the calibration will be aborted 

and the display will show “Failed: Signal Too Small!” or “Failed: Signal Too Large!”.

The previous calibration value will be retained.

7. Press 



to select the next calibration phase.

8. Repeat this process for each input type until all the phases are calibrated. For each phase, 

ensure that the correct input is applied, using the correct connections.

9. Once all calibration phases are completed, recorder versions will display the Calibration 

Reminder Date. If required, this can be changed to the date of your next calibration check. 
Ensure that Calibration Reminders are enabled in Input Configuration to receive a 
reminder.
