PF109F Digital three-phase multifunction meterDetailed product description：

PF109F digital three-phase multifunctional meter is an intelligent and universal measuring instrument developed to meet the requirements of modern AC measurement. It can directly measure AC voltage, current, active power, reactive power, power factor, frequency, and is compatible with single-phase, three-phase three wire system, three-phase four wire system, and three voltage three current system wiring methods The LCD display and four function selection buttons are located on the front panel of the instrument panel. The LCD can display three measurement data simultaneously, and the left side of the LCD is its display prompt. Three phase wiring system, alarm voltage or current parameters can be set. Lock the measurement data. Very suitable for on-site measurement of three-phase power frequency electricity in fields such as motors, electrical appliances, water pumps, power, transformers, etc., with PC communication interface Easy to automate measurement Easy to operate, compact in size, lightweight, and affordable in price, it is an ideal upgraded product for pointer watches The YS106B power supply, YS37C or YS37D audio power supply produced by our factory can be selected for calibration of various single-phase AC voltmeters, ammeters, power meters, frequency meters, power factor meters, etc.
