The measurement point illumination is
active during approx. 45 seconds (only
T140).
Maintenance
When using FLUKE T100/T120/T140 testers in
compliance with the instruction manual, no par-
ticular maintenance is required. If functional er-
rors occur during normal operation, stop using
it and contact your nearest authorized service
center.
If the device is not used for an extended
period of time, the batteries must be remo-
ved to prevent the risk of leaking batteries
and damage to the device.
Cleaning
Prior to cleaning, remove voltage tester from all
measurement circuits. If the instrument is dirty
after daily usage, it is adviseable clean it by
using a damp cloth and a mild household deter-
gent. Never use acid detergents or dissolvents
for cleaning. After cleaning, do not use the vol-
tage tester for a period of approx. 5 hours.
Calibration Interval
The voltage testers must be calibrated periodi-
cally and checked by our service department at
regular intervals to ensure the specified accu-
racy of measurement results. We recommend a
calibration interval of one year.
Battery Replacement

1
LED does not light up when the pro-
bes are short-circuited, the batteries must be
replaced.
