Features
Ampere Meter Current testing requires no additional purchase of transformer. The instrument is equipped with a high precision transformer,Easy to use, Suitable for novice or professional use.
In the watch head, l-set fine-tuning potentiometer can calibrate the voltage and current error by itself.
Ampere Meter 100% brand new and high-quality,high strength, high cost performance.
Split-type: easy to install, the transformer is separated from the instrument, and the transformer can be installed according to the actual position of the measurement. (It can lengthen the lead at the second end of the transformer to reach the ideal installation position).
Two-wire system: No need to connect the power supply, red and black lines to measure the voltage at the same time to the meter head power supply (no need to split polarity).
Specification: The range of voltage measurementAC100V-300VThe range of current measurement10A(0.00~9.99A)Display modeDouble 0.39 bright LED digital tubeDisplay color( Optional )Red + red/ red + blue/ blue + blueMeasurement accuracy1% ± 2 digitsDisplay0.39 inches LED digital tube displayMeasurement speed about 2 times per secondDimensions70 * 40 * 30 mmInstallation dimensions68 * 38 mmPower supply line, measuring line lengthabout 150mm"split" transformer lead lengthabout 100mmWorking temperature -10 ~ + 50 ℃Working humidity10 ~ 80% (without condensation)Working pressure80 ~ 106 kPaSunshineNo direct exposure
Package List: 1 * Current voltmeter head1 * mutual inductance coil 1 * Adapter
Note: The wiring sequence of the instrument is: the circuit of the current loop is connected first, the 220V voltage is finally connected, after connecting the 220V power supply, it can not touch any parts and circuits behind the instrument to prevent the danger of electric shock. Split: Green terminal is connected to AC transformer CT, two yellow lines are connected to measure AC voltage, do not connect wrong, connect wrong will cause instrument damage, the responsibility is self-conceited. This meter is designed based on the principle of capacitance step-down, because the higher the frequency, the smaller the impedance of the capacitor, so it is not suitable to be used in high-frequency electronic speed regulation, non-city electric sine wave frequency, or other occasions where there are high-frequency components, otherwise it is easy to burn down! When selecting the range, the larger the range is, the greater the range is, the greater the error is. It is suggested that 1.5 times the actual test value be.
