Operation
Accuracy Considerations
2
2-11
Exposures in the AUTO mode which do not trigger
the reset will accumulate in the electrometer until a
reset occurs either from a proper exposure or
manually. If exposure reset occurs, the display will
include the most recent exposure and the
accumulated exposures which
did not reset.
2.12 Operational Checks
Regular monitoring of the instrument's performance is necessary to achieve maximum accuracy.
2.13 Drift Rate
Periodic measurements of the drift rate should be recorded for reference when long exposure periods are
used. Refer to Table 2-2.
2.14 Battery Voltage
Correct battery voltage is important for proper operation of the unit. Installation and replacement of the
battery requires the removal of the rear access panel. Refer to Figure 2-1. A MN1604 alkaline battery
(P/N 16-29 or equivalent) is recommended. However, any standard 9 V transistor battery will work, but
with shorter life. The battery should be replaced after a maximum of one year's use.
Turn the unit off before replacing the battery.
2.15 Zero Set
Due to aging of circuit components, small changes in the zero reading can be expected over the lifetime
of the unit. A Zero adjustment, located on the rear panel, is provided to permit field adjustment as follows:
1. Turn the unit ON.
2. Wait five minutes.
3. Set the front panel switch to DOSE.
4. Set the rear panel switch to MAN.
5. Press RESET.
6. Adjust ZERO if necessary so that the display shows 0.000.
