Battery Installation Or Replacement; Operation; Precautions - Simpson 896 Operator's Manual

3. Avoid prolonged exposure or usage in areas subject to temperature and
humidity extremes, vibration, mechanical shock, dust, corrosive fumes,
and strong electrical and electromagnetic interferences.
4. Be sure the transducer cap is firmly in place. (Removal of the Transducer
cap may invalidate calibration.)
5. If the Instrument has not been used for 30 days, check battery for leak-
age and replace if necessary.
6. It is recommended that the Instrument be returned to the factory annually
(sooner if required) for a complete overall check, adjustment, and cali-
bration.
7. When not in use, store instrument in a room free from temperature ex-
tremes, dust, corrosive fumes, mechanical vibration or shock. If storage
time is expected to exceed 30 days, remove the battery.

Battery Installation Or Replacement

1. Set the Rotary Switch of the 896 to the OFF position.
2. Remove the battery cap (Table 3-1, item 1) by turning it counterclock-
wise.
3. If replacing the battery, remove the old battery.
4. Snap the battery connector onto the mating terminals of the replacement
battery. The connector is polarized to allow it to be connected only one
way.
5. Tuck the connector cable neatly under the battery so it will not interfere
when the battery cap is replaced, and slide the battery into the battery
compartment. Replace the battery cap.

OPERATION

This section contains information required to operate the Instrument in a safe
and proper manner. Follow the instructions herein and in the Operator's
Manual for the Sound Level Meter.
3.1

Precautions

Do not place the operating Calibrator tightly against the ear. The high sound
levels could be harmful, especially to someone with a hearing deficiency.
Check the calibration of the 896 periodically or whenever accuracy is in doubt.
Do this by comparing Instrument with another 896 Calibrator or a reference
Sound Level Meter known to be accurate. If another 896 or reference Sound
Level Meter is unavailable, return the Instrument to the factory for a complete
overall check.
Be sure the Sealing Ring in the Transducer Cap is not damaged and that the
leak-to-atmosphere opening is not blocked. (Table 3-1, item 5.)
