· Turn off the meter and remove the test leads from the meter
before opening the back cover or the case.
· Do not operate the meter with the back cover or portions of
the case removed or loosened.
· To avoid false readings, which could lead to possible electric
shock or personal injury, replace the battery as soon as the
low battery indicator ( ) appears.
· To avoid electric shock, do not contact any open conductor
with hands or skin. Do not ground yourself while using the
meter.
· Remaining endangerment:
When an input terminal is connected to dangerous live
potential, it is to be noted that this potential can occur at all
other terminals.

CAT III
- Measurement category
III
is for measurements
performed in the building installation. Examples are
measurements on distribution boards, circuit breakers,
wiring, including cables, bus-bars, junction boxes, switches,
socket-outlets in the fixed installation, and equipment, for
example, stationary motors with permanent connection to the
fixed installation. Do not use the meter for measurements
within Measurement Categories IV.
CAUTION
To avoid possible damage to the meter or to the equipment
being tested, follow these guidelines:
· Disconnect circuit power and discharge all capacitors before
measuring resistance, diode, temperature, or continuity.
· Use the proper terminals, function, and range for measure-
ments.
· Before measuring current, check the meter’s fuses and turn
off the power to the circuit before connecting the meter to the
circuit.

Note:
1. Use K type thermocouple
2. Accuracy does not include error of the thermocouple probe.
3. Accuracy specification assumes ambient temperature
is stable to ±1˚C. For ambient temperature changes of
±5˚C, rated accuracy applies after 1 hour.

If the temperature being measured is out of the range of 0ºC to
1000ºC or 0ºF to 1400ºF, the display may show a reading; but the
measurement error may be large or the thermocouple may be damaged.
