YDeLi S200 double clamp digital phase voltmeter ampsmeter

Product functions and features:
 
S200 dual clamp digital phase volt ampere meter is a multi-function instrument specially designed for field testing. It has the characteristics of high precision, high stability, low power consumption and convenient operation. The AC voltage and AC current can be measured directly in the condition that the measured circuit is not open, and the phase between the two voltage, the two current and the voltage current can be measured. In addition, the power factor and power of the circuit can be measured indirectly. The three-phase phase sequence can be judged, the transformer connection group, the perceptual and the capacitive circuit can be tested for two times. The differential protection system of the road and the bus reads out the phase relationship between the CT of each differential protection group, checks the wiring of the watt hour meter correctly or not, and repairs the line equipment. The instrument is super large LCD display, the word is as high as 40mm, with backlight and display at a glance. It is applicable to electric power, petrochemical, metallurgy, railway, meteorology, industrial and mining enterprises, scientific research institutions, metrology departments, etc.
