Product Introduction

ETCR9310B Large Caliber U-shaped Wireless H/L Current Meter, also known as U-shaped H/L Clamp Current Meter, overhead line load tester, high voltage load tester, high altitude current tester, high voltage current telemeter, which is used for measurement of H/L AC current of overhead line below 110kV. The unique U-shaped opening structure realizes unhindered measurement, and on-site testing is particularly convenient. It is widely used in substation, power plant, industrial and mining enterprise, testing station, electrician maintenance department for current detection and field electrician operation,etc.
ETCR9310B Large Caliber U-shaped Wireless H/L Current Meter is composed of u-shaped clamp jaw, receiver and insulating rod. Testing below 110kV requires insulating rod (testing below 500kV can be customized), no request insulating rod when measure below 600V. The meter has data hold, memory function, etc.
1.Unique U-shaped opening structure realizes unhindered measurement, and on-site testing is particularly convenient.

3.Ultra-wide current range: 0.00A~9999A.
4.Adopt with wireless transmission method, transmission distance 100m.
5.Memory: data storage 99 groups.

Technical Parameter

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.
