IMPORTANT: A ground path must be provided between one of the
output terminals of the charging unit and the ground reference of
the Fieldmeter and Adapter Plate. This is normally provided by
holding the Charger in one hand and the Fieldmeter with Adapter
Plate in the other. If this is not possible, you must use a test lead
to connect one to the charger output terminals and the fieldmeter
ground connection.

Calibration
The overall accuracy of the 19447 Test Kit and the 19445 digital
fieldmeter is +/- 5% nominal. Calibration of the meter and the
Ionization Test Kit should only be performed by the factory. Both
the 19447 and the 19445 are calibrated to NIST traceable
standards. Contact our Customer Service Department for details.
Maintenance
BATTERY CARE
The battery in the Model 19447 and 19445 should be replaced
annually and whenever you plan an extended period of unattended
monitoring. See specifications for battery replacement type.
CLEANING
It is important to keep the insulators on the adapter plate clean
and free of contaminates that may cause surface leakage. To test
the performance of the adapter plate, charge the plate and note
the discharge rate in a non-ionized area. The self discharge rate to
10% of original voltage should not be less than five minutes.
The area around the aperture of the Model 19445 must be kept
clean to ensure accurate, drift-free readings. Never touch the
aperture with anything. To remove dust or other particulate matter,
use low-pressure instrument-grade air. To remove more severe
contamination, spray or flush with the smallest practical amount of
clean technical-grade of isopropyl alcohol. Then allow the
instrument to air dry for several hours.
