Features and Functions

• Adopting digital multiplier technology, through calculation and analysis of collective data, realizes voltage, current, power and energy four quadrants measurement
• Energy accumulation measurement: Receiving starting signal through photoelectric head or manual switch inputting, displaying relevant energy value
• Testing: Photoelectric head, manual switch and electronic energy meter active and passive signal receiving, tested meter errors continuous display, errors of two tests and average error value display
• Meter constant can be decimal
• Energy meter wiring detection: New calculation method makes the results of wiring detection (48 kinds of) independent of current, which is more suitable for the real condition of worksite
• Phase sequence measurement: Current voltage phase sequence measurement and display under three-phase three-wire mode.
• Data storage: Testing results of 100 meters (1000 meters) can be saved, queried and transferred to the computer
• Real time clock: Testing time can be record at real time and the clock works normally when the device is shut off
• Data transferring: Mutual data transferring to PC via serial communication port    
• Temperature measurement: Temperature measurement, current environment temperature display
• Three different frequency standard pulse signals(positive or negative, active and reactive) output, FH1=100KHz, FH2=10KHz, FL=1Hz (TTL), pulse equivalent automatic display  
• User-friendly menu and excellent user guidance  
• Large LCD display, three phases voltage, current, power and power factor synchronous display, or vector diagram, phase angle, frequency etc synchronous
