The following safety precautions must be observed to ensure
maximum personal safety during the operation, service and repair of
this meter:
1. Read these operating instructions thoroughly and completely be-
fore operating your meter. Pay particular attention to WARNINGS
which will inform you of potentially dangerous procedures. The in-
structions in these warnings must be followed.
2. Always inspect your meter, test leads and accessories for any sign
of damage or abnormality before every use. If any abnormal condi-
tions exist (broken test leads, cracked cases, display not reading,
etc.), do not attempt to take any measurements.
3. Do not expose the instrument to direct sun light, extreme tempera-
ture or moisture.
4. Never ground yourself when taking electrical measurements. Do
not touch exposed metal pipes, outlets, fixtures, etc., which might
be at ground potential. Keep your body isolated from ground by us-
ing dry clothing, rubber shoes, rubber mats, or any approved insu-
lating material.
5. To avoid electric shock use CAUTION when working with voltages
above 40 Vdc or 20 Vac. Such voltages pose a shock hazard.
6. Never exceed the maximum allowable input value of any function
when taking a measurement. Refer to the specifications for maxi-
mum inputs.
7. Never touch exposed wiring, connections or any live circuit when
attempting to take measurements.
8. Do not attempt to operate this instrument in an explosive atmos-
phere (i.e. in the presence of flammable gases or fumes, vapor or
dust).
9. When testing for the presence of voltage, make sure the voltage
function is operating properly by reading a known voltage in that
function before assuming that a zero reading indicates a no-
voltage condition. Always test your meter before and after taking
measurements on a known live circuit.
10. Calibration and repair of any instrument should only be performed
by qualified and trained service technicians.
11. Remember: Think Safety, Act Safely.
