About the Adapter (ADP109)
The CAL150 and CAL200 calibrators require a 1/4-inch
adapter (ADP109). If your dosimeter package included a
calibrator, the 1/4-inch adapter was attached. If needed,
additional adapters are available for purchase.
To install the adapter, firmly insert the narrow edge into
the slot on the bottom of the calibrator. The adapter’s
part number should be visible around its circumference.
About Post-Calibration Data
We recommend that you calibrate prior to the
measurement and again directly after the measurement, and before to
downloading the data files. This creates a post-measurement entry in the
Calibration History.
If you calibrate after downloading data files, connect your dosimeter to G4 or the
LD Atlas app once again to automatically add the previous calibration results to
the measurement file. In this case, the calibration result just prior to the
measurement start is saved as the pre-calibration level and the calibration result
that occurred directly after the measurement stop is saved as the post-
calibration level.
If calibrations are infrequent, it’s possible that long periods of time lapse
between the pre- and post-calibration levels. If this occurs, the calibration levels
added to a data file may not be as accurate as they would be if you calibrate just
before and just after a measurement.
The Spartan 730 dosimeter automatically keeps an internal history of all
calibrations. This calibration history is permanently retained unless a format and
restore to factory defaults is needed.
