Monroe Electronics Charge Plate - Ionizer Performance Analyzer - model 287A - Manual (Page 9)

Section 4
MAINTENANCE
Precautions —
User maintenance should be limited to keeping the instrument clean and free from physical
damage. Store the instrument in its protective carrying pouch when not in use. Do not allow
any object to come in contact with the white insulators under the measurement plate. Do
not wrap cords around these insulators.
Cleaning —
If self-discharge becomes excessive (out of spec.), clean the insulators with a clean swab
and a 70%/30% mix of clean technical grade isopropyl alcohol and de-ionized water.
Fingerprints and other contaminants may be removed from the case with a clean lint-free
cloth dampened in the same solution. DO NOT use soap or detergent.
Battery —
Need for battery replacement is indicated by a warning message whenever the battery
voltage persistently dips below 7.5 volts. A fresh battery should be installed when this
occurs. The battery should be removed if the unit is to be stored for an extended period of
time. Removal of the battery when the unit is off does not disturb settings or data.
Calibration —
Calibration is not a user function and is beyond the scope of this manual. Calibration
information is available from the factory. Monroe Electronics recommends annual
calibration and/or when the instrument is damaged or repaired or where called for more
often by contract. We offer repair and calibration services for a fee.
