The measured value shows on the display.
Note:
•
The test leads can add 0.1Ω to 0.2Ω of error to resistance
measurement. To obtain precision readings in low-resistance
measurement that is the range of 400.0Ω, short-circuit the input
terminals beforehand, using the relative value function button REL to
automatically subtract the value measured when the testing leads are
short-circuited from the reading.
•
For high-resistance measurement (>1 MΩ), it is normal taking several
seconds to obtain a stable reading.
•
If Ω reading with shorted test leads is not <0.5Ω, check for loose test
leads, incorrect function selection, or enabled Data Hold function.
•
The LCD displays OL indicating open-circuit for the tested resistor or
the resistor value is higher than the maximum range of the Multimeter.
5.3 Capacitance Measurement
Warning:
To avoid damage to the multimeter or to the equipment under test,
disconnect circuit power and discharge ail high-voltage capacitors
before measuring capacitance.
Use the DC Voltage function to confirm that the capacitor is discharged.
Never attempt to input over 60V in DC or 30V rms in AC to avoid personal
dangerous.
The multimeter's capacitance ranges are: 40.00nF, 400.0nF, 4.000µF,
40.00µF and 100.0µF. To measure capacitance, connect the Multimeter as
follows:
1. Insert the red test lead into the HzVΩ terminal and the black test lead
into the COM terminal.
2. Set the rotary switch to
3. Connect the test leads across with the abject being measured
The measured value shows on the display
Note:
•
For testing the capacitor with polarity, connect the red test lead to
anode & black test lead to cathode instead.
•
To increase the accuracy of capacitance measurement especially
when measuring under 400nF, use REL mode to automatically
subtract the multimeter built-in equalized capacitance and residual
capacitance of test leads from the result
•
It takes a longer time when testing a high capacitor value, the testing
time is around 15 seconds in 100µF range.
5.4 Frequency and Duty Cycle measurement
5.4.1 Frequency Measurement
The measurement ranges are from 10Hz to 40MHz To measure frequency,
connect the Multimeter as follows:
