Test accuracy

±2% ±5dgt (The wire is located near the center of the bottom of the U-shaped jaw, 23℃±2℃)

Position error

The wire under test should be as close as possible to the center of the bottom end of the U-shaped jaw

data storage

99 groups, the "MEM" symbol indicates during the storage process, and the flashing display of the "FULL" symbol indicates that the storage is full

Line voltage

Test of bare wires below 60kV (operation with insulating rod, fully extended telescopic insulating rod)

Data retention

In the normal test mode, press the HOLD key to keep the data, the "HOLD" symbol is displayed, and then press the HOLD key to cancel

Data access

The "MR" symbol indicates that the stored data can be flipped up and down

Overflow display

Over-range overflow function: "OL A" symbol display

No signal indication

When the receiver does not receive the transmitted signal, the "no- -" symbol is displayed dynamically

Automatic shut-down

About 15 minutes after power on, the meter will automatically shut down to reduce battery consumption

battery voltage

When the battery voltage is lower than 4 .8V, the receiver will display the low battery voltage symbol "", reminding to replace the battery
