3.3 CURRENT MEASUREMENT
3.3.1
Insert the black test lead into “COM” jack, the red one to “mA” or
“10A”jack.
3.3.2 Set the range knob to a proper DC or AC mA/A range, If the
measured voltage is unsure beforehand, set the range knob to the
highest range, then reduce it gradually until get the highest
resolution readings.
3.3.3 Connect the test leads to the circuit under test, the LCD displays
the measured voltage value.
NOTE:
a.
If LCD displays “OL”, it means over range, set the range knob to a
higher range.
b.
When measuring current,
mA hole should not exceed 200mA,10A
hole should not exceed 10A(test time should be less than 10 sec.)
3.4 RESISTANCE MEASUREMENT
3.4.1
Insert the black test lead to “COM” jack and the red one to
“V/Ω/Hz”
jack.
3.4.2 Set the range knob to a proper resistance range, connect the test
leads across to the resistance being measured.
NOTE:
a.
If the resistance value being measured exceeds the max value of
the range selected, LCD displays "OL", , set the range knob to a
higher range. When the resistance is over 1M
Ω, the meter may take
a few seconds to stabilize. This is normal for high resistance
readings.
b.
When input terminal is in open circuit, overload displays.
c.
When measuring in-line resistance, be sure that power is off and all
capacitors are discharged completely.
d.
Do not input any voltage at this range.
3.5 CAPACITANCE MEASUREMENT
3.5.1
.Insert the red test lead to “V/Ω/Hz”
terminal and the black one to
“COM” jack.
3.5.2 Set the range knob to a proper capacitance range, connect the test
leads to the capacitor being
measured
（
note: the polarity of red
test lead is “+”
）
.
NOTE:
a.
If the resistance value being measured exceeds the max value of
the range selected, LCD displays "OL".
