8 Major Functions

• Test Function: real-time waveform display (4 channels voltage / 4 channels current); voltage and current true RMS; voltage DC component; current and voltage peak; current and voltage maximum/minimum value within a certain time; phasor diagram display; The measurement of each phase harmonics reaches 50 times; the histogram shows the harmonic ratio of each phase current and voltage; the calculation of total harmonic distortion (THD); Active/reactive/apparent power value and total value of each phase; Each phase active/reactive/apparent electrical energy value and total value of each phase; transformer K factor calculation; calculation of COS φ displacement and power factor (PF); flicker calculation; three-phase unbalance calculation ( Voltage and current).
• Capture and Monitoring Functions: Capture detection the instantaneous change of electric network voltage and current parameters, including voltage and current fluctuations, voltage and current swell, sag, short-time interruptions, transient over voltage, impulse current, and current and voltage instantaneous distortion. The instrument can store up to 150 groups of transient waveforms simultaneously.
• Start-up Current Monitoring: It can monitor the inrush current of the circuit and the starting current of the electrical equipment, helpful for the correct design of installed capacity. It can display the rise/fall curve of the effective value in start process, the envelope curve of the start current, 4-channel current and 4-channel voltage waveform. After triggering, can be recorded about 100s, and store all current and voltage instantaneous values and waveform curves in each cycle within 100s.
• Record and Storage Function: All test parameters of basic test functions (Urms, Uthd, Ucf, Uunb, Hz, Vrms, Vthd, Vcf, Vunb, PST, Arms, Athd, Acf, Aunb, KF, W, VAR, VA, PF, COSφ, TANφ), voltage 50 times harmonic, current 50 times harmonic, total of 123 parameters for recording, and generate the trend diagram, record data for a long time as required. (Simultaneously select 20 parameters to record once every 5 seconds, can be recorded about 300 days).

• Alarm Function: The limit value of the selected parameters can set according to the require to monitoring whether the parameters exceed the limit,when exceed the limit setting will generate the alarm log , such as voltage overvoltage, current overcurrent, unbalance degree over-limit, certain harmonic ratio over-limit, frequency over-limit, active power over-limit, total harmonic distortion over-limit, etc. At most to set 40 groups of alarm monitoring parameters, each groups can set different monitoring parameters (including 50 times harmonics with 123 different parameters) and the limit value, and set the minimum time of over-limit. Stored Max 12800 groups alarm log.
• Screen capture function: Screen capture can be taken in any test page to store the present screen image, and record time and test mode automatically, Such as saving current voltage waves, harmonic histograms, phasor diagrams, etc. Save up to 60 screenshots simultaneously.
• Communication Function: Through USB communication with the computer, the monitoring software can display the waveform of power quality analysis and test in real time, and can read the detected and captured transient waveform, trend chart record, alarm list, test screenshot, etc.
• Setting Function: The user can set the time and date, the display contrast and brightness, and the corresponding color of each phase line in the instrument; the connection mode and power network type of the instrument can be set; can select different current clamp and different voltage test transformation ratio; Chinese menu or English menu can be selected.
