VIII. Operations
To avoid false reading, replace the battery if the battery low power symbol
GI appears. Also pay special attention to the warning sign &, beside the test
lead jack, indicating that the tested voltage or current must not exceed the
values listed on the device.
1.AC/DC voltage measurement (see Figure 2b)
1) Switch the dial to position.
·v-·
2) Insert the black test lead into the COM jack, the red test lead into the
"VOmN jack. Connect test leads with the load in parallel.

&.Notes:
• Do not measure voltage over 250Vrms, or it may expose users to electric
shock and damage the device. If the range of the voltage to be measured is
unknown, select the maximum range and reduce accordingly.
• Please pay extra attention when measuring high voltage in order to avoid
electric shock.
• Before using the device, it is suggested to measure a known voltage for
verification.
2.Reslstance measurement (see Figure 2b)
1) Switch the dial to ·n· position.
2) Insert the black test lead into the COM jack, the red test lead into the 'VOmA"
jack. Connect test leads with the resistor in parallel
&.Notes:
• Before measuring resistance, switch off the power supply of the circuit, and
fully discharge all capacitors.
• If the resistance when probes are shorted is more than 0.50, please check
if test leads are loosened or damaged.
• If the resistor is open or over the range, the "OL• symbol will be displayed on
the screen.
• When measuring low resistance, the test leads will produce 0.10-0.20
measurement error. To obtain accurate measurement, the measured value
should subtract the value displayed when two test leads are shorted.
• When measuring high resistance above 1 MO, it is normal to take a few
seconds to steady the readings. In order to quickly obtain steady data, use
short test wires to measure high resistance.
3. Continuity measurement (see Figure 2b)
1) Switch the dial to • .,,1 • position.
2) Insert the black test lead into the COM jack, the red test lead into the "VOmA"
jack. Connect test leads with the points to be tested in parallel
3) If measured points' resistance >510, circuit is in open status.
If measured points' resistance S100, circuit is in good conduction status,
buzzer will go off
.&.Notes:
Before measuring continuity, switch off all power supplies and f u lly discharge
all capacitors.
4. Diode measurement (see Figure 2b)
1) Switch the dial to· -M-" position.
2) Insert the black test lead into the COM jack, the red test lead into the "VOmA·
jack. Connect test leads with the diode in parallel
3) "OL" symbol appears when the diode is open or polarity is reversed.
For silicon PN junction, normal value: 500 - 800mV (0.5 - 0.8V).
4Notes:
• Before measuring PN junction, switch off the power supply to the circuit,
and fully discharge all capacitors
5. Capacitance measurement (only for 72-13430, see Figure 2a)
1) Switch the dial to capacitance test.
2) Insert the black test lead into the COM jack, the red test lead into the
"VOmA• jack. Connect test leads with the capacitor in parallel
3) When there is no input, the device displays a fixed value (intrilsic capacitance).
• For small capacitance measurement, to ensure measurement
accuracy, the measured value must be subtracted from intrinsic capacitance.
• Users can measure small capacity capacitors with relative measurement
functions (REL) (the device will automatically subtract the intrinsic
capacitance)
&Notes:
• If the tested capacitor is shorted or its capacity is over the specified range
"OL • symbol will be displayed on the screen.
• When measuring large capacitors, it may take a few seconds to obtain
steady readings.
• Before measuring capacitors (especially for high voltage capacitors), please
fully discharge them.
6. DC measurement (see Figure 3)
1) Switch the dial to DC test.
2) Insert the black test lead into the COM jack, the red test lead into the
"VOmN jack. Connect test leads with the tested circuit in series.
Figure 3
.&.Notes:
• Before measuring, switch off the power supply of the circuit and carefully
check the input tenninal and range position.
• If the range of the measured current is unknown, select the maximum
range and then reduce accordingly.
• Please replace the f use with the same type.
10Ajack: Fuse 10A/250V <J>5x20mm
VOmA jack: Fuse 0.2A/250V Cl>5x20mm
• When measuring, please do not connect the test leads with any circuit in
parallel. Otherwise there is a risk of damage to the device and human body.
• If the tested current is over 10A, each measurement time should be less
than 10 seconds and the next test should be after 15 minutes.
7. AC measurement (only for 72-13430, see Figure 3)
Similar to DC Measurement.
Please refer to Section 6 "DC measurement (see Figure 3t
8. Temperature measurement (only for 72-13435, see Figure 5)
1) Switch the dial to temperature test.
2) Insert K•thermocouple into the device and fix the temperature probe to
the measured object. Read the value when it is stable.
.&.Notes:
• Only K-thermocouple Is applicable. The measured temperature should
be less than 250*C/482"F ("F="C*1.8+32)
