Precautions

1. The meter is a high-voltage test equment. Before using it, observe whether the meter is in good condition. If the following conditions occur, you must stop using it, and perform corresponding s and repairs to avoid electric shock and unsafe accidents.

A: The appearance of the meter is obviously damaged (such as cracks or damage in the shell, broken skin on the test lead, etc.);

B: The instrument was severely squeezed during transportation;

C: The meter has been idle for a long time under improper conditions (such as in the bathroom or a relatively humid place, etc.).

2. Do not open the casing of the meter during the measurement proce to avoid electric shock and unsafe accidents.

3. During the measurement, there is a large voltage input from the test lead. Do not touch the bare wire or the metal part of the test lead directly with your hands to avoid electric shock.

4. Although sometimes all the phase indicators are not lit, there is still a voltage loop. Pay attention to prevent electric shock.

5. The circuit voltage should not be higher than 600V during measurement to avoid unsafe accidents.

6. When measuring 200V ACV, the continuous use time should be no more than 60 minutes; when measuring 600V ACV, the continuous use time should be no more than 4 minutes.

7. It is not allowed to use this meter for measurement in rainy outdoor or in a relatively humid environment, so as to avoid unsafe accidents.

8. Do not let the instrument come into contact with water or other corrosive liquids, and do not place it in an environment with direct sunlight or high temperature and relatively humid temperature, so as not to affect its test performance.

9. Non-profeionals are forbidden to open the casing of the meter, so as not to affect its test performance.

10. The operator who uses this instrument should have received special training, understand the related knowledge of high-voltage operation and measurement, and carry out the measurement operation strictly in acconce with this manual.

11. Please place this manual in a place that is relatively easy to read, so that you can read it at any time.

Technical characteristics

Working voltage: 60~600V (three-phase alternating current)

Maximum withstand voltage: 2000V/min (pulse voltage 4000V)

Measurable frequency range: 20Hz~400Hz

Continuous use time: no more than 60 minutes at 200V ACV, no more than 4 minutes at 600V ACV

Appearance descrtion

1. LED for open phase check: Three orange LEDs indicate U phase, V phase and W phase respectively.

2. LED for phase sequence check: one red LED and one green LED respectively

3. Draw strap: put it on the wrist to prevent the instrument from slping off the hand.

4. Test lead.

5. Test lead: red corresponds to U (R) phase (L1, R);

Yellow corresponds to V (Y) phase (L2, S);

Green corresponds to W (B) phase (L3, T).

Instructions

Connect the test probe of this instrument to the wire to be tested (cannot be pinched directly by hand), which can be a wire end, socket or the middle part of the phase wire (when measuring in the middle part of the phase wire, the insulation layer of the wire needs to be strped Go, the wire core inside can only be measured. At this time, pay special attention to safety to prevent electric shock. For the convenience of users, there is a special test cl in the instrument acceories. Insert the test cl on the metal probe of the test lead and tighten it. Conveniently cl it anywhere for measurement). At this time, the meter will indicate the status of the open phase and the sequence based on the phase of the light emitting diode (LED) and the .
