    The electrometer must be calibrated for each individual detector and radiation source. A special feature inherent in the 37-720 is the ability to switch between DET A and DET B, using the front panel switch, so that two detectors can be utilized for monitoring at the same time. This feature is applicable when the measurement is being taken in the dose or rate mode.
