Pay attention to the following issues when using a clamp ammeter
Phase sequence test:
(1) Turn the gear to the phase sequence detection gear;
(2) Yellow, black, and red test leads are inserted into c, COMb, and VΩa sockets in sequence;
(3) Correspond the red, black, and yellow of the test leads to A, B, and C (or L1, L2, and L3) respectively. When the red and black test leads are connected, the indicator light is slightly bright, and when the yellow test lead is connected again, the indicator light is on, indicating that it is a positive phase sequence; when the indicator light is off, it indicates a reverse phase sequence;
(4) The phase sequence file can also measure the phase-to-phase voltage at the same time.
AC voltage measurement:
(1) Turn the gear to the AC voltage gear;
(2) Insert the red and black test leads into the VΩa and COMb sockets respectively;
(3) Connect the other ends of the red and black test leads to the point to be tested and read the value.
AC current measurement:
(1) Select the appropriate current gear;
(2) Completely clamp the single wire to be tested with the jaws and read the data;
Note that the maximum test current of this instrument is only 600A, and the current exceeding 600A cannot be tested.
DC voltage measurement:
(1) Select the appropriate DC voltage file;
(2) Insert the red and black test leads into the VΩa and COMb sockets respectively;
(3) Connect the other ends of the red and black test leads to the point to be tested and read the value.
Resistance measurement:
(1) Turn the gear to resistance gear 2kΩ;
(2) Insert the red and black test leads into the VΩa and COMb sockets respectively;
(3) Connect the other ends of the red and black test leads to the point to be tested and read the value;
Note: Only in the state of power failure can the resistance be tested.
Line continuity measurement:
(1) Turn the gear to the diode gear.
(2) Insert the red and black test leads into the VΩa and COMb sockets respectively.
(3) Connect the other ends of the red and black test leads to the point to be tested and read the value. If the value is small and the multimeter emits a "beep" sound, the circuit is connected; on the contrary, if the value shows "1" and the multimeter does not sound, the circuit is open circuit or the resistance value is very large.
Note: Only in the state of power failure can the circuit continuity be tested.
