RESISTANCE MEASUREMENT
1.
Connect the BLACK test lead to the COM jack and the RED to the VΩ jack.
(NOTE: The polarity of the RED lead is positive "+")
Set the function switch at Ω position, connect test leads across the resistance
2.
under measurement.
NOTE:
1.
For resistance above 2MΩ, the meter may take a few seconds to stabilize reading.
This is normal for high resistance measuring.
2.
When the input is not connected, i.e. at open circuit, the figure "OL" will be displayed
under over-range condition.
3.
When check in circuit resistance, be sure the circuit under test, has all power removed
and all capacitors are fully discharged.
AC/DC CURRENT MEASURE
1.
Set Function/Range Switch to the 400A range. If the display indicates one or more
leading zeros. Shift to 40A range to improve the resolution of the measurement.
2.
Push "FUNC" button to select AC or DC Mode, and then the symbol ~ or
is shown on LCD.
3.
Press the "REL(ZERO)" button to zero the meter.
4.
Press the trigger to open the transformer jaws. And clamp one conductor only it is
impossible to make measurements when two or three conductors are clamped at the
same time.
5.
Display reading is showing the current value.
CONTINUITY/DIODE TEST
1.
Connect the BLACK test lead to the COM jack and the RED to the VΩ jack.
2.
Set the function switch at
continuity or diode test mode.
3.
In continuity test, if the circuit resistance under test is lower than 50Ω, built-in buzzer
will sound.
4.
If diode test mode is selected, connect the RED and BLACK test leads to anode and
cathodes of the diode under test separately. The forward voltage drop of this diode in
V will be displayed.
