ETCR4000A Auto Double Clamp Digital Phase VA Meter Tester Voltammeter with Color Screen Item Type: VA Meter Material: ABS Color: As shown in the picture Function: Simultaneously measure two channels of AC voltages, currents, phases between voltages, phases between currents, phases between voltages and currents, frequency, phase sequence, active power, reactive power, apparent power, and power factor. Identify the transformer wiring group, inductive and capacitive circuits.Secondary circuit loop and bus protection system can be tested. It can also used to check the phase relationship between CT groups, and whether the meter’s wiring is correct or not, or repair line equipment, etc. Power Supply: DC9V 1.5V 6 x AA (not included) Range (Automatic): Current: AC 0.0mA~20.0AResolution: 0.1mAPhase: 0.0°~360.0° Frequency: 45.00Hz~65.00Hz Active Power: 0.0W~12kw Reactive Power: 0.0var~12kvar Apparent Power: 0.0VA~12k VA Power Factor: -1~+1. Jaw Size: Approx. 7.5x13mm / 0.30x0.51in Data Storage: 1200 groups USB Interface: USB interface, upload the stored data to the computer, easy to analyze and manage the data Power Consumption: the maximum power consumption of the backlight is 135mA, and the battery can work continuously for about 6 hours; when the backlight is turned off, the power consumption of the instrument is 90mA, and the battery can work continuously for about 9 hours. Display Mode: 2.8 inch TFT color LCD screen Detection Rate: About 2 seconds/time Data Hold: Press the HOLD key to retain the data during the test, the "HD" symbol is displayed Automatic Shutdown: After about 15 minutes of inactivity, the meter will automatically shut down to reduce battery consumption Backlight Function: Yes, suitable for dim places and night use; turn off the backlight after five minutes of no operation Working Temperature and Humidity: -10℃~40℃; below 80%RH Storage Temperature and Humidity: -10℃~60℃; below 70%RH Insulation: ≥100MΩ between the instrument circuit and the cover shell Structure: Double insulation, with insulating anti-vibration cover How e
