1. Connect the black probe to terminal COM and the red probe to terminal V/Ω/
2. Set the function switch to position 300V~
3. Connect the test plungers to the circuit and read the value displayed on
screen once it has stabilised.
Important : if the measured voltage is > 300 V, the screen can display the
voltage value but measuring is dangerous.
1. Connect the black probe to terminal COM and the red probe to terminal V/Ω/
2. Set the function switch to position 300V
3. Connect the test plungers to the circuit and read the value displayed on
screen once it has stabilised.
Important : if the measured voltage is > 300 V, the screen can display the
voltage value but measuring is dangerous.
1. Set the function switch to position 2A~ ou 20A~ ou 200A~ depending to
the desired rating
2. Open the clamp and surround 1 single conductor (phase or neutral) if possible
in the centre to improve accuracy, and read the value displayed on screen once
it has stabilised.
1. Connect the black probe to terminal COM and the red probe to terminal V/Ω/
2. Set the function switch to position 200kΩ ou 2000Ω depending to the desired rating
3. Connect the test plungers to the circuit and read the value displayed on screen
once it has stabilised. If the resistance is less than 30Ω, the buzzer will sound.
Before measuring resistance on a circuit, ensure that the circuit power supply
has been disconnected and that all the capacitors have been discharged.
1. Connect the black probe to terminal COM and the red probe to terminal V/Ω/
2. Set the function switch to position 2000Ω
3. Connect the test plungers to the circuit and, if the buzzer sounds, the
continuity is good (the current flows) when the resistance being measured is
less than about 30Ω, the built-in buzzer will sound.
1. Connect the black probe to terminal COM and the red probe to terminal V/Ω/
2. Set the function switch to position
3. Connect the test plungers to the diode :
(A) test in the direct direction: connect the black plunger to the cathode and the red
plunger to the anode, measuring the voltage in the direction of a normal diode; the
screen will display 0.5 to 0.7V and the blocked direction will display "1"
(B) test in the opposite direction: connect the black plunger to the anode and
the red plunger to the cathode. The diode is good if the display shows "1".
