Tips: Resistance measurement of AC clamp meter
To avoid damage to the AC clamp meter or the device under test, all power supply to the circuit under test should be cut off and all high voltage capacitors fully discharged before measuring the resistance.
Resistance measurement:
- Turn the rotate dial to the resistance function.
- Insert the black test lead into the COM jack,and the red test lead into the resistance jack.
- Use the other end of the test pen to measure the resistance of the circuit under test.
- Read the measured resistance value from the LCD.
Note:
- The measured resistance on the circuit will usually differ from the resistance rating.
- In the measurement of low resistance, in order to measure accurately, short-circuit the two test leads, read out the resistance of the test leads short-circuit, after measuring the resistance to be measured to be subtracted from the resistance.
- At 20MΩ, the meter may take a few seconds to stabilize the reading, which is normal for high resistance measurements.
- When the meter is open, the display will show '0L', indicating that the measured value is out of range.
AC clamp meter has AC current range 0-600A, AC/DC voltage range 0-600V, resistance range 0-20MΩ, maximum display value 1999 and maximum jaw opening size 36mm. True RMS clamp meter can be used for sine wave signal measurement. AC clamp meter also has special functions of automatic power off, back light and LED torch.
