Precision fully automatic micro water testerTest operation instructions

1. Connect the ground wire to ensure reliable grounding of the instrument.

2. Wiring:

Connect the test clamp correctly according to the condition of the tested transformer.

a、 Single phase transformer: The yellow and black wires of the high-voltage cable are clamped to the terminal of the high-voltage side of the tested transformer.

The yellow and black wires of the low-voltage cable are clamped to the terminal of the low-voltage side of the tested transformer.

b、 Three phase transformer (Formula 1): Connect the 3-color clamps of the high voltage and low voltage cables in yellow, green, and red to correspond to phase A, phase B, and phase C.

c、 Three phase transformer (method 2): Connect the four-color clamps of the high and low voltage cables in yellow, green, red, and black corresponding to phase A, phase B, phase C, and neutral point O.

Precision fully automatic micro water testerSecurity measures

1. Before using this instrument, be sure to read this manual carefully.
2. The operator of the instrument should have knowledge of using electrical equipment or instruments.
3. The instrument should be reliably grounded during use.
4. This instrument is powered by an internal lithium-ion battery or AC220V ± 10% 50/60HZ ± 1HZ
5. The output voltage of the instrument is high, attention should be paid to safety to prevent electric shock.
6. This instrument can be used both indoors and outdoors, but should be avoided from harsh environments such as rain, corrosive gases, excessive dust, high temperatures, and direct sunlight.
7. Instruments should avoid severe vibrations.
8. The maintenance, care, and adjustment of instruments should be carried out by professionals.
9. The yellow, green, red, and black colors of the test clamp correspond to A, B, C, and O of the transformer, respectively. Do not connect the high and low voltage cables in reverse.
10. When measuring single-phase, only use yellow and black wire clamps, do not use them incorrectly, and unused test clamps should be suspended.
