Overload protection: 600V DC or AC rms
3. OPERATION
3.1 DC and AC Voltage Measurement
1) Connect the black test lead to "COM" socket and red test lead to the
"V Ω Hz" socket.
2) Set the selector switch to desired “mV ” or “V ” position.
3) Press “SELECT” key to choose “DC” or “AC” measurement.
4) Measure the voltage by touch the test lead tips to the test circuit where the
value of voltage is needed.
5) Read the result from the LCD panel.
6) On AC range, press “Hz/%” key to measurement frequency or duty cycle.
3.2 DC and AC Current Measurement
1) Connect the black test lead to "COM" socket. For measurement up to
600mA, connect the red test lead to the " µ AmA" socket; for measurement
from 600mA to 15A, connect the red test lead to the "15A" socket.
2) Set the selector switch to desired “
µ
A ”
、
“mA ” or “A ” position.
3) Press “SELECT” key to choose “DC” or “AC” measurement.
4) Remove power from the circuit under test and open the normal circuit path
where the measurement is to be taken. Connect the meter in series with
the circuit.
5) Read the result from the LCD panel.
6) On AC range, press “Hz/%” key to measurement frequency or duty cycle.
3.3 Resistance Measurement
1) Connect the black test lead to "COM" socket and red test lead to the
"V Ω Hz" socket.
2) Set the selector switch to desired “ ” position.
3) Connect tip of the test leads to the points where the value of the resistance
is needed.
4) Read the result from the LCD panel.
Note:
When take resistance value from a circuit system, make sure the power is cut
off and all capacitors need to be discharged.
3.4 Capacitance Measurement
1) Connect the black test lead to "COM" socket and red test lead to the
"V Ω Hz" socket.
2) Set the selector switch to desired “ ” position.
3) Press “SELECT” key to choose Capacitance measurement.
4) Connect tip of the test leads to the points where the value of the
capacitance is needed.
5) Read the result from the LCD panel.
Note: Before testing, discharge the capacitor by shorting its leads together.
Use caution in handing capacitors because they may have a charge on
them of considerable power before discharging.
