ETCR ETCR9310B 大口径ワイヤレスH/L電圧U型電流計 (Φ68mm, AC 0.00A～9999A)

Power Supply: DC6V alkaline dry battery (1.5V AAA×4)

Display Mode: 4-digit LCD display, backlight function, suitable for dim place

LCD Size: 47mm×28.5mm

Measurement Method: Non contact U-shaped CT

Transmission Mode: 433MHz wireless transmission, transmission distance about 100m

Clamp Jaw Size: Φ68mm

Sampling Rate: 2 times/second

Measurement Range: 0.00A~9999A(50/60Hz automatic)

Solution: 0.01A

Shift Gear: 0.00A~9999A Fully automatic shift gear

Test Accuracy: ±2%rdg±5dgt(The wire is in the center position near the bottom of the U-shaped clamp jaw)

Position Error: The measured conductor should be placed as close as possible to the center of the bottom of the U-shaped clamp jaw, not close to the top of the U-shaped clamp jaw. The testing error at the top of the U-shaped clamp jaw should increase by about twice or more.

Memory: 99 groups, in storage process “MEM” symbol display, “FULL” symbol flicker indicate storage full

Line Voltage: Testing below 110kV requires insulating rod (testing below 500kV can be customized).

Data Hold: Press HOLD key to hold data in test mode, “HOLD" symbol display, press HOLD key again to cancel this function.

Data Access: "MR" symbol display, can look up all storage data

Overflow Display: Exceed measure range overflow function:"OL A" symbol display

No Signal Indication: When the receiver has not received transmit signal, dynamic display "no- -"symbol

Automatic Shutdown: After 15 minutes power on, the meter shuts down automatically without any operation to reduce battery consumption

Battery Voltage: When battery voltage is lower than 4.8V±0.2V,low battery voltage symbol display and remind to replace battery.

Meter Size: Meter: 107mm×252mm×31mm; Receiver: 78mm×165mm×42mm

Weight: Meter: about 235g (include battery), Receiver: about 280g(include battery), Total weight: about 4.23kg(include insulating rod and battery)

Telescoping Insulating Rod Size: About 4300mm

Interference: Avoid 315MHz, 433MHz same frequency signal interference

Insulation Strength: AC 220kV/rms (The telescopic insulating rod is completely pulled apart, between the two ends)

Working Temperature & Humidity: -10℃~40℃; below 80%RH
