Functioning
The indicated voltage range is 180÷270 V with a reading accuracy of 10 V. The switched on LED light indicates the voltage value described on its height. The voltage value between 190 V and 260 V is indicated by the green LEDs. The extreme values 180 V and 270 V are indicated by a red LED. Voltage lower than 190 V is indicated by the 190 V red LED flashing. Voltage higher than 270 V is indicated by the flashing of the diode located at the top, or in case of the “bar” mode of operation by flashing of the entire bar graph. The device can operate in “bar” or “single diode” mode. The selection is made by shorting (or not) terminals 10-12.
Voltage value is shown for 10 seconds, when you touch the F&F logo on the front of the housing.
