3. OPERATION

3.1 DC Voltage Measurement

1) Connect the black test lead to "COM" socket and red test lead to the "V Hz" socket.

2) Set the selector switch to desired "V

3) Measure the voltage by touch the test lead tips to the test circuit where the

value of voltage is needed.

4) Read the result from the LCD panel.

3.2 AC Voltage Measurement

1) Connect the black test lead to "COM" socket and red test lead to the "V Hz" socket.

2) Set the selector switch to desired "V

3) Measure the voltage by touch the test lead tips to the test circuit where the

value of voltage is needed.

4) Read the result from the LCD panel.

5) Press "Hz/DUTY" key to measurement frequency or duty cycle.

3.3 DC and AC Current Measurement

1) Connect the black test lead to "COM" socket. For measurement up to 400mA, connect

the red test lead to the " AmA" socket; for measurement

from 400mA to 10A, connect the red test lead to the "10A" socket

2) Set the selector switch to desired "µA

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/DUTY" key to measurement frequency or duty cycle.

3.4 Resistance Measurement

1) Connect the black test lead to "COM" socket and red test lead to the "V Hz" socket.

2) Set the selector switch to desired "

3) Press "SELECT" key to choose Resistance measurement.

4) Connect tip of the test leads to the points where the value of the resistance is needed.

5) 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.

3.5 Capacitance Measurement

1) Connect the black test lead to "COM" socket and red test lead to the "V Hz" socket.

2) Set the selector switch to desired "

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:

a) 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.

b) Before testing, press "REL△" key to eliminate the zero error.

c) When testing 4000 F capacitor, note that there will be approx. 30 seconds time lag.

3.6 Diode and Audible continuity Test

1) Connect the black test lead to "COM" socket and red test lead to the "V Hz" socket.

2) Set the selector switch to desired "

3) Press "SELECT" key to choose Diode or Audible continuity measurement.

4) Connect the test leads across the diode under measurement, display shows the approx.
