ETCR ETCR1050 Wireless High Voltage Phase Sequence Detector (10V～500kV, 45.0Hz～65.0Hz, 0°～360°)

Power Supply: Host: 3.7V 2600mAh, rechargeable lithium battery; Detector: DC3.7V 1000mAh,rechargeable lithium battery

LCD Size: 3.5 inch color display; display area: 71mmX53mm

Phase Detecting Method

1. Contact mode phase detecting: circuit line below110kV

2.Non-Contact mode phase detecting:when >10kVand <110kVdisplay, phase detecting can be performed on the insulation skin wire,when the line voltage>110kV, must adopt non-contact mode to testing

Phase Detecting Voltage: AC 10V～500kV

Phase Detecting Distance: 200m

Communication Distance: 130m (communication distance between the host and the detector)

Phase Sequence Qualitative: In phase:-20°~20°;out phase:100°~140°and 220°~260°

Range: 

test phase：0°～360°

test frequency: 45.0Hz～65.0Hz

Transmit Frequency: 433MHz

Phase Indication: Vector graphics and numbers are displayed at the same time

Power Indication: The detector has a green power indicator

Electricity Test Indication: du--du--du" buzzing sound

Voltage Level Display Range: 0.4kV～110kV

Display Rate: 2 times/second

Memory: 200 sets (no data will be lost if the battery is powered down or replaced)

Automatic Shutdown: The meter will automatically turn off after about 15 minutes of power-on

Battery Voltage: The host battery has a 4-cell power display. When there is only 1 cell or 0 cells, please charge; when the indicator light of the detector flashes quickly, it means that the battery voltage is low. Please charge.
