Note
- The test leads can add 0.1Ω to 0.3Ω of error to resistance measurement. To obtain precision
readings in low-resistance measurement, that is the range of 200Ω, short-circuit the input terminals
beforehand and record the reading obtained (called this reading as X). (X) Is the additional
resistance from the test lead. Then use the equation: measured resistance value (Y) - (X) = precision
readings of resistance.
- For high-resistance measurement (>1MΩ), it is normal taking several seconds to obtain a stable
reading.
- When there is no input, for example in open circuit condition, the Meter displays "1".
- When resistance measurement has been completed, disconnect the connection between the
testing leads and the circuit under test.
Warning!
To avoid damage to the Meter or to the equipment under test, disconnect the tested circuit
power when measuring on line capacitors and discharge all high-voltage capacitors before
measuring capacitance. Use the DC voltage function to confirm that the capacitor is discharged.
Never attempt to input over 60 V in DC or 30V rms in AC to avoid personal injuries.
To measure capacitance, connect the Meter as follows:
1. Insert the capacitor to be tested into capacitance jack.
2. Set the rotary switch to an appropriate measurement position in kHz range.
3. Connect the leads across with the objet 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.
• Ehen the tested capacitor is shorted or the value is overloaded, the LCD display "1".
• To minimize the measurement error caused by the distributed capacitor, the connection
should be as short as possible.
• It is normal to take a while for zeroing when changing over the measurement range. This
process will not affect the accuracy of the final reading obtained.
