Three-phase electrical parameter meter

Uni-T UT267B three-phase electrical parameter meter Smart three-phase meter (digital phase voltmeter) also known as three-phase digital voltmeter/ammeter. Fully automatic, multifunctional digital smart meter specially designed for on-site measurement with the following features: high accuracy, high stability, low power consumption and easy operation. Without breaking the current circuit, it can measure AC three-phase voltages and AC currents, phase shift angles between voltages and currents, frequency, phase sequence, active, reactive and apparent powers, power factor, graphically shows voltage and current vectors; It can identify transformer windings, inductive circuits and capacitive circuits, and enables measurement of bus differential protection; it also allows reading the phase of differential protection between CT units, checking the correctness of kilowatt-hour meter wiring, equipment wiring condition, etc. Measurement ranges: - AC current: 0 mA ~ 20 mA ±(1.5%+3) - AC voltage: 0 V ~ 600 V ±(1.5%+3) - Frequency: 45 ~ 65 Hz ±(2%+3) - Power: 0 W ~ 12 kW ±(3%+3) - Apparent power: 0 VA ~ 12 kVA ±(3%+3) - Reactive power: 0 VAR ~ 12 kVAR ±(3%+3) - Power factor: -1 ~ +1 ±0,03 - Phase angle: 0° ~ 360° ±1° - Sum of current vectors: 0 mA ~ 60 A - Phase sequence test Features: - Maximum current jaw size: sharp (7.5 x 13 mm); round (35 x 40 mm). - Automatic change of measurement ranges - RS-232 interface - Data recording - LCD backlighting - Freeze measurement - Input impedance for DCV: >2 MOhm - Power supply: 6x 1.5 V LR6 battery - Dimensions: 196 x 92 x 54 mm - Meter weight: 550 g - Gross weight: 2600 g
