•
Do not use the Tester if it operates abnormally. Protection
provided by the Tester may be impaired. When in doubt, have
the Tester serviced.
•
Do not operate the Tester around explosive gas, vapor, or
dust.
•
Do not apply more than the rated voltage, as marked on the
Tester, between terminals or between any terminal and earth
ground.
•
When measuring hazardous voltage, verify the Tester’s
operation by measuring a known voltage.
•
Only the test probes and batteries are serviceable. When
servicing, use only specified replacement parts.
•
To determine the LEDs and beeper are working correctly,
short the test leads together. The beeper sounds (if enabled)
and all LEDs and display segments (T+ PRO) switch on
briefly indicating correct operation.
•
Comply with local and national safety requirements when
working in hazardous locations.
•
Use proper protective equipment, as required by local or
national authorities when working in hazardous areas.
•
Use caution when working above 30 V ac rms, 42 V peak, or
60 V dc. Such voltages pose a shock hazard.
•
When using probes, keep fingers away from the probe tips.
•
Connect the common test lead before connecting the live test
lead. When disconnecting the test leads, disconnect the live
test lead first.
•
Do not operate the Tester with the battery door or portions of
the cover removed or loosened.
•
When the batteries are depleted, self test will not function.
•
When the beeper is disabled, it will not sound until the beeper
is reactivated.
•
For voltages above 240 V, you must only connect to a voltage
source for a MAXIMUM of 30 seconds and then disconnect for
a MINIMUM of 300 seconds.
•
Perform a self test before any measurements are taken for
voltage, continuity, resistance, or rotary field. See “Self Test.”
•
Exercise caution when performing measurements on PLC
inputs. When measuring relay control voltages on PLCs, be
aware that this may open or close the relay/switch.

Caution
Although the Tester may be used with depleted batteries,
replace depleted batteries immediately to avoid Tester damage
from battery acid leakage.
