- Page 3 Calibration Before calibration: The probe must have the correct service-life time stamp. Set the date and time in the meter before the probe is attached. It is not necessary to recalibrate when moving a calibrated probe from one HQd meter to another if the additional meter is configured to use the same calibration options.
