the “V/Ω” jack, and the black probe into the “COM” jack.
4-4-2. Connect the tested probe to the tested circuit and obtain the
value from the LCD screen.
Caution:
1. Please cut off all the power in the circuit and all capacitors exhausted
residual charge before measuring the online resistance in order
to ensure measurement correctly. (it is better to pick up one side
of the resistance)
2. It is prohibited to input voltage in the resistance range.
3. The display will show “OL” if the tested resistance of the circuit is
open.
4. When the probes are connected shortly, there will be some
clutter resistance about 1Ω.
4-5. interrupted circuit and diode measurement
4-5-1. Set the function switch to the Ω/ / range. Put the red
probe into the “V/Ω” jack, and the black probe into the “COM”
jack.
4-5-2. Set the function switch to the“ / ” range.
4-5-2. Connect the probes to the tested circuit, and if the buzzer
ringing, the value is <(50±5)Ω.
4-6. temperature measurement
4-6-1. Set the function switch to the relative range (°C).Put the red
probe into the “V/Ω” jack, and the black probe into the “COM”
jack.
4-6-2. Put the exposed end of the temperature probe on the surface
of the tested objective.
