Maintenance
Very little maintenance is required for the Survey Meter, but some periodic
attention may be necessary, especially if the Survey Meter is used in harsh
industrial conditions.
 Warnings
To prevent possible electrical shock, fire, or personal injury:
• Do not operate the Product with covers removed or the case
open. Hazardous voltage exposure is possible.
• Use only specified replacement parts.
• Have an approved technician repair the Product.
• Use care when handling, the surface below the High Voltage
Board is conductive!
• Many components on the printed circuit board are static
sensitive. Obey all ESD precautions when you touch the
printed circuit board assembly.
Preventive Maintenance
The desiccant must be renewed and replaced periodically. See the How to
Contact Fluke section.
Note
Install fresh batteries prior to performing any calibration on the
Survey Meter.
Routine Cleaning
Do not immerse the Survey Meter. The Survey Meter is not waterproof; liquid
could damage the circuits. The Survey Meter should be kept clean and free from
dirt and contamination. To clean the Survey Meter, wipe with a damp cloth using
any commercially available cleaning or decontaminating agent.
Storage
If the Survey Meter is to be stored prior to use, pack it in the original container, if
possible, and store in an environment free of corrosive materials, fluctuations in
temperature and humidity, vibration or shock. Store the Survey Meter with the
two 9 volt batteries removed.
