NCV measurement from the AC voltage signal into the RLD IC, the measurement results show five grades, 0 ~ 50mV display EF, 50 ~ 100mV / 100 ~ 150mV / 150 ~ 200mV / 250mV or more to 4 show a '-' character (adjustable) and with(?) the rhythm buzzer sound.

Applications need to be adjusted according to the value of Rx and the induction line. NCV measurement and the minimum resolution that can be set E2 (In 0.1mV): 25h (H) & 24h (L) set in base NCV measurements, 27h (H) & 26h (L) NCV resolution setting,

Calculated as the measured value

- in base) / = 0 ~ 4 Resolution (rounded result), the count is greater than 4. 4. Such as:

25h (H) & 24h (L) = 0064h, 27h (H) & 26h (L) = 0096h, measuring the induced signal = 50.0mV, then LEVEL = (50.0-10.0) /15.0~=2, the display section 2 '- -. "

Optional PT1.2 NCV function as a control indicator (E2 provided F9h.bit0 = 1). When no signal PT1.2 = 0, a letter.

When the number PT1.2 with buzzer output, buzzer PT1.2 = 1, and 0 otherwise. This setting has no effect on other functions, PT1.2 = 1.
