SECTION 1 –SAFETY INFORMATION
Safety Information
Understand and follow operating instructions carefully.
Use the Instrument only as specified in this manual; otherwise, the protection provided
by the Instrument may be impaired.
WARNING
Identifies hazardous conditions and actions that could cause
BODILY HARM
or
DEATH
CAUTION
Identifies conditions and actions that could DAMAGE the Instrument or equipment
under test
WARNING
-
Examine the instrument and probes before use. Do not use the instrument
if it is wet or damaged
-
When using test leads or probes, keep your fingers behind the finger guards.
-
Remove the test lead from the instrument before opening the battery cover
or instrument case.
-
Always use the correct terminals, switch position and range for measurements.
-
Never attempt a voltage measurement with the test leads inserted into the
“A”input terminals.
-
Verify the instrument is operating correctly by measuring a known voltage
-
before use. If in doubt, have the instrument serviced.
-
Do not apply more than the rated voltage, as marked on the instrument,
between terminals or between any terminal and earth ground.
-
Do not attempt a current measurement when the open-circuit voltage is above
the fuse protection rating.
-
Only replace a fuse with the correct type and rating as specified in this instruction
manual.
-
Use caution when measuring voltages above 30 Vac rms, 42 Vac peak or 60
Vdc. These voltages pose a shock hazard.
-
To avoid false readings that can lead to electric shock, replace the battery as
soon as the low battery indicator appears in the display.
-
Disconnect the circuit power and discharge all high-voltage capacitors before
making resistance, current, continuity, diode or capacitance measurements.
-
Do not use the instrument in a hazardous area or around explosive
gasses or vapours.
-
Wear suitable personal protective equipment when working around or near
hazardous live conductors which could be accessible.
