4. DC measurement is default, press blue button to select AC measurement.
5. Open the circuit path to be tested. Touch the red testing leads to the more positive side of
the break; touch the black probe to the more negative side of the bread. Reversing the leads will
produce a negative reading, but will not damage the Meter.
6. Turn on power to the circuit; then read the display.
AC measurement displays the True RMS value.
7. DC measurement displays the effective value of sine wave (mean value response)
Turn off power to the circuit and discharge all highvoltage capacitors. Remove the Meter and
restore the circuit to normal operation.
When a ACA function is selected, you can press the
Yellow Button
to view the AC + DC True
RMS value in the primary display. To exit, please
EXIT
button.
Note
- If the value to be measured is unknown, use the maximum measurement position and reduce
the range step by step until a satisfactory reading is obtained.
- When the measured current is 5A, continuous measurement is allowed.
- When the measured current is between 5A-10A, continuous measurement 10 seconds and
interval more than 15 minutes.
- When current measurement has been completed, disconnect the connection between the
testing leads and the circuit under test and remove testing leads away from the input terminals of
the Meter.
C. Measuring Resistance
Warning!
To avoid harms to you, please do not attempt to input voltage higher than 60V DC
or 30V rms AC.
To avoid possible damages to the Meter or to the devices under test, disconnect
circuit power and discharge all the high-voltage capacitors before
measuring resistance.
To measure resistance, set up the Meter as shown in Figure 3-3 and follow the following procedure:
1. Insert the red test lead into the terminal and the black test lead into the
COM
terminal.
2. Set the rotary switch to
; press
BLUE
button to select measurement mode.
3. Connect the test leads across with the object being measured.
The measured value shows on the display.
The
BLUE
button cycles among resistance, continuity, and diode.
