• basic measurement function

AC voltage, DC voltage, AC current, resistance, capacity

Continuity, diode, frequency/duty ratio measurement

temperature measurement, RTD measurement, peak measurement(PEAK)

AC + frequency(AC+Hz)measurement

relative measurement(REL_%)

maximum value, minimum value, average measurement(MAX/MIN/AVG)

• Display speed rate: twenty times/ second fast, five times/ second slow, analog bar refreshing speed: twenty times/ second as fast as possible.
• TRMS value, measurement bandwidth 20Hz～50kHz.
• Selectable manual or auto-range measurement.
• Measurement data display hold (DIS_HOLD)and auto hold (AUTO_HOLD)function.
• Peak measurement function, 1ms of peak value sample capture, which can capture spike pulse.
• Selectable dB measurement for 1～2400Ω reference impedance.
• Low pass filter function can improve the measurement effects of the complex waveform caused by inverter and frequency conversion motor.
• Vocalize if the continuity measurement is below 50Ω.
• TC measurement: K graduation, built-in temperature transmitter, auto cold- compensation, and display ℃ or ℉ for temperature.
• Large screen allows multi-data display, showing measured value and other relevant measured information simultaneously.
• Multi-data parameter recording function: manual recording, timing recording and is convenient to inquire the recorded data.
• The meter is equipped with data storage with large capacity, to store as many as 2000(groups) data of field calibration. The data can be read from the meter or uploaded to the user’s PC.
• on-line communication function

• VICTOR189A can undertake wired communication with infrared serial port of the compatible USB connection.
• Supports SCPI commands of industrial standard, and can realize remote control of the meter by equipment driving software.
• the WIFI wireless communication supports two modes:
  • AP mode, namely hot mode, PC can undertake wireless communication with the meter through WIFI.
  • STA mode,namely router mode,which is separated as STA (Client)mode and STA (Server) mode. PC needs the supports from WIFI router to communicate with the meter.
• The infrared wire communication function will conveniently help the user to get multiple data parameters by powerful, friendly man-machine interface, and make data storage, settlement and management in form of figures or tables.
