Precautions:

1. This meter uses the capacitor step-down principle, because the higher the frequency the smaller the impedance of the capacitor, it is not suitable for use in high-frequency electronic speed control, non-mains frequency sine wave, or other high-frequency components occasion, or else it is easy to burn !!!

2. The instrument wiring sequence is: first connect the current loop line, 220V voltage finally connected, after turning on the 220V power supply, do not touch any components and circuits, to avoid electrical shock hazard.

Key indicators:

1. Accuracy: 1% ± 2 words

2. Display: 0.39 inches of LED digital display, voltage - red, current - green

3. Measurement speed: approximately 2 times per second

4. Dimensions: 70 x 40 x 30 mm

5. Installation size: 68 x 38mm

6. Power line, measuring line length: about 150mm

7."Split" tranformer wire length: about 100mm

Extreme working conditions:

1. Working temperature: -10 ~ + 50 �

2. Operating humidity: 10 ~ 80% (non-condensing)

3. Working pressure: 80 ~ 106kPa

4. Sunlight: no direct exposure
