To avoid electrical shock and/or damage to the
instrument, do not apply more than 250Vdc or
℃
250Vac rms between the
terminal and the
COM terminal.
To avoid electrical shock, do not use this instrument
when voltages at the measurement surface exceed
60v dc or 24v rms. Ac.
To avoid damage or burns. Do not make
temperature measurements in microwave ovens.
To measure temperature:
1. Set the rotary switch to ℃ range and the LCD will show
the current environment temperature.
2. Connect the "com" plug and "+" plug of the special
multi-function socket to the COM and hFE terminals.
3. Insert 'K' type thermocouples into the special multi-function
socket，Takings care to observe the correct polarity.
4. Touch the object with the thermocouple probe for
measurement.
5. Read the stable reading from LCD.
3.2.9 Current measurement
To avoid damage to the Meter or injury if the fuse
blows,
never
attempt
an
in-circuit
measurement where the open-circuit potential to
earth is greater than 250V.
To avoid damage to the meter, check the meter's
fuse before proceeding. Use the proper terminals,
function, and range for your measurement. Never
place the test leads in parallel with a circuit or
component when the leads are plugged into the
current terminals.

Current is the flow of electrons through a conductor.
The Meter's DC current ranges are 20.00mA, 200.0mA
and 10.00A；AC current ranges are 2.000mA, 200.0mA
and 10.00A.
To measure current:
1. Turn off the power of the measured circuit. Discharge all
the high voltage capacitors.
2. Set the rotary switch to the proper range.
3. Connect the black test lead to the COM terminal and
the red test leads to the mA terminal for a maximum of
200mA. For a maximum of 10A, move the red test lead
to the 10A terminal.
4. Break the circuit path to be tested.
Connect the black test lead to the more negative side of
the break; connect the red test lead to the more positive
side of the break. (Reversing the leads will give a
negative reading, but will not damage the Meter.)
5. Turn on the power of the measured circuit, and then
read the display. Be sure to note the measurement
units at the right side of the display (mA or A). When
only the figure "1" displayed, it indicates overrange
situation and the higher range has to be selected.
6. Turn off the power of the measured circuit and discharge
all the high voltage capacitors. Remove the test leads and
recover the measured circuit.
