3. Touch Run DC Zero to start the dc zeros routine. The status of the dc zero
If the Calibrator is not warmed up, the display prompts to continue or

4. Touch Close to proceed with Calibrator use.
DC Zeros Reminder
Specifications require that dc zeros be run at least every 30 days. If 30 days passes and dc
zeros is not done, the display prompts to run the process.
To override the message and run dc zeros at a more convenient time, touch Cancel. To
run dc zero at this time, touch OK.
If this message shows after powering on the Calibrator, let the Calibrator
warm up before running dc zeros. Otherwise an error message shows that
indicates that the Calibrator is not warmed up. To ensure the best
performance, the warmup should be completed.
Calibration
This section provides procedures to calibrate the Calibrator to external standards, adjust
the range if necessary, and for do a calibration check.
In order to maintain traceability, these requirements must be met:
•
•
Calibration Check and range calibration are optional procedures that are provided to

7-8
calibration is shown as the Calibrator progresses through a series of steps. When
completed, the Calibrator shows "Calibration complete".
Calibration to external standards must be completed at the start of the calibration
