b.
Before measuring, LCD display might not be zero, the residual
reading will decrease gradually and should be disregarded.
c.
When measuring large capacitance, LCD may display an unstable
value due to creepage or breaking.
d.
Discharge
all
capacitors
completely
before
capacitance
measurement to avoid damage.
e.
Do not input any volt at this range.
f.
This range is for automatic range test,
measuring the range from
10nF to 2000uF.
g.
UNIT: 1mF=1000uF 1uF =1000nF 1nF=1000pF
3.6 FREQUENCY MEASUREMENT
3.6.1 Apply th
e test lead or shield to cable to “COM” or ““V/Ω/Hz”
terminal.
3.6.2 Switch the knob to frequency range,
and connect the test leads
across the signal source or the measured load.
NOTE:
a.
When input is 10Vrms or less,
a
reading is possible but maybe over-
range.
b.
Shielded cable is recommended when measuring small signals
under noisy conditions.
c.
Be careful when measuring high volt circuit.
d.
Do not input a voltage over DC 250V or AC peak factor to avoid
damage to the meter.
e.
This range is for automatic range test,
Measuring the range from
10Hz to 2MHz
3.7 DIODE AND CONTINUITY TEST
3.7.1
Insert the black test lead to “COM” terminal and the red one to
“V/Ω/Hz” jack( Note: the polarity of red test lead is“+”).
3.7.2
Set the range knob to“
”range, connect the test leads to the
diode being measured, reading is the approximation of the diode
positive volt drop.
3.7.3 Connect the test leads to two points of the measured circuit, if
buzzer sounds, the resistance is lower than approx.
(
50±20
)
Ω.
3.8 DATA HOLD
Press the “HOLD/BL”,
LCD displays “HOLD”,
the present value is held on
LCD,
press it again, the function is cancelled.
