Feature:
Split type: easy to install, the transformer is separated from the meter, the transformer can be installed according to the actual position of the measurement (the lead of the secondary end of the transformer can be lengthened to achieve the ideal installation position)
Fixed type: The transformer is fixed on the meter
AC voltage, ammeter with the same screen, two-color, dual display, highlight large font;
Simple wiring of the instrument:
Set the trimmer potentiometer in the meter head, you can calibrate the voltage and current error by yourself.
Two-wire system: no need to connect the power supply, the red and black wires are connected to the meter while supplying voltage (no polarity is required)
Current testing does not require the purchase of a separate transformer. The meter comes with a high-precision transformer.
The split-type transformer has a back cover that is safer, more convenient, and more secure! ! !
Specification:
Working temperature: -10 ~ +50 °C
Working humidity: 10~80% (no condensation)
Working pressure: 80 ~ 106kPa
Measurement accuracy: 1% ± 2 words
Measuring speed: about 2 times per second
Dimensions: 70 × 40 × 30 mm
Installation size: 68×38mm
Power supply line, measuring line length: about 150mm
"Separate" transformer lead length: about 100mm
Note:
1. The wiring sequence of the instrument is: first connect the current circuit line, 220V voltage is last connected, after turning on the 220V power supply, you can not touch any components and circuits behind the instrument to prevent electric shock.
2. This table is designed using the principle of capacitor buck. The higher the frequency, the smaller the impedance of the capacitor, so it is not suitable for high-frequency electronic speed regulation, non-mains sine wave frequency, or other high-frequency components. Otherwise Easy to burn!!!
