1.3.1 Service and Maintenance
User Service
To prevent electric shock do not remove the instrument cover. There are no user
serviceable parts inside. Routine maintenance or cleaning of internal parts is not
necessary. Avoid the use of cleaning agents or chemicals on the instrument, some
chemicals may damage plastic parts or lettering. Any external cleaning should be
done with a clean dry or slightly damp cloth. Schematics, when provided, are for
reference only. Any replacement cables and high voltage components should be
acquired directly from eec.Refer servicing to eec. customer support department.
Service Interval
The instrument, its power cord, test leads, and accessories must be returned at least
once a year to eec customer support department for calibration and inspection of
safety related components. eec will not be held liable for injuries suffered if the
instrument is not properly maintained and safety checked annually.
User Modifications
Unauthorized user modifications will void your warranty. eec will not be responsible
for any injuries sustained due to unauthorized equipment modifications or use of parts
not specified by eec. Instruments returned to eec with unsafe modifications will be
returned to their original operating condition at the customers expense.
1.3.2 Test Station
Location
Select an area away from the main stream of activity which employees do not walk
through in performing their normal duties. If this is not practical because of production
line flow, then the area should be roped off and marked for HIGH VOLTAGE
TESTING. No employees other than the test operators should be allowed inside.
If benches are placed back-to-back, be especially careful about the use of the bench
opposite the test station. Signs should be posted: "DANGER - HIGH VOLTAGE
TEST IN PROGRESS - UNAUTHORIZED PERSONNEL KEEP AWAY."
Work Area
Perform the tests on a non-conducting table or workbench, if possible. If you cannot
avoid using a conductive surface, be certain that it is connected to a good earth
ground and the high voltage connection is insulated from the grounded surface.
There should not be any metal in the work area between the operator and the location
where products being tested will be positioned. Any other metal in the work area
should be connected to a good ground, never left "floating".
Position the tester so the operator does not have to reach over the product under test
to activate or adjust the tester. If the product or component being tested is small, it
may be possible to construct guards or an enclosure around the device to be tested.
Construct the guards of a non-conducting material such as clear acrylic, so that the
item being tested is within the guards or enclosure during the test. If possible, the
guards or enclosure should also contain safety switches that will not allow the tester to
operate unless the guards are in place or the enclosure closed.
