● Measured value displayed on the bottom area of LCD
Resistance value : N-E resistance determined by measuring
resistance between neutral wire (N) and earth
wire (E) is displayed.
Voltage value : N-E voltage is displayed if voltage between N-E
is 8 V or higher. When N-E voltage is higher than
8 V, KEW 4506 cannot measure resistance.
N-E resistance < 2 N-E voltage > 8 V Meas. OFF
