to the “INPUT” jack.
2) Set the function switch to range position.
3) Connect the test leads across the source or load to be
measured.
4) Press the SEL button, to select V or V range
5) Read LCD display. The polarity of the RED lead connection will
be indicated when making a DC measurement.
Note:
a. In small range, the meter may display an unstable
reading when the test leads have not been connected to
the load to be measured. It is normal and will not affect
the measurements.
b. To avoid damage to the meter, don’t measure a voltage
which exceeds 600Vdc (for DC voltage measurement) or
600Vac (for AC voltage measurement).
6-2. Measuring Current
1) Set Function/Range Switch to the A~ range.
2) 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.
3) Display reading is flowing the conductor AC current.
6-3. Measure Resistance
1) Connect the BLACK test lead to the “COM” jack and the RED
to the “INPUT” jack (Note: The polarity of the red test lead is
positive “+”).
2) Set the range switch to Ω or range position.
3) Connect the test leads across the load to be measured.
4) Read the reading on the display.
Note:
a. For resistance measurements >1MΩ, the meter may
take a few seconds to stabilize reading. This is normal
for high-resistance measurement.
b. When the input is not connected, i.e. at open circuit, the
symbol “OL” will be displayed as an over range indicator.
c. Before measuring in-circuit resistance, be sure that the
circuit under test has all power removed and all
capacitors are fully discharged.
