LED Digital Display AC 100~300V Voltmeter 0100A Ammeter(Red BluE)

About this item

• Features: brand new and highquality. Splittype: 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 at the second end of the transformer to reach the ideal installation position). Twowire 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). Current testing requires no additional purchase of transformer. The instrument is equipped with a high accuracy transformer. In the watch head, lset finetuning potentiometer can calibrate the voltage and current error by itself. Specification: The range of voltage measurement AC100V300V The range of current measurement 100A(0~99A) Display mode Double 0.39 bright LED digital tube Display color(Optional) Red + red red + blue blue + blue Measurement accuracy 1percent + 2 digits Display 0.39 inches LED digital tube display Measurement speed about 2 times per second Dimensions 70 * 40 * 30 mm Installation dimensions 68 * 38 mm Power supply line, measuring line length about 150mm split transformer length about 100mm Working temperature 10 ~ + 50 celsius Working humidity 10 ~ 80percent (without condensation) Working pressure 80 ~ 106 kPa Sunshine No direct exposure Package List: 1 * Current voltmeter head 1 * 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 selfconceited. This meter is designed based on the principle of capacitance stepdown, because the higher the frequency, the smaller the impedance of the capacitor, so it is not suitable to be used in highfrequency electronic speed regulation, noncity electric sine wave frequency, or other occasions where there are highfrequency 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. .brand new and highquality.
