The other combinations of FC1, FC2, FC3, and FC4 are for ADP modes. In ADP modes
, if FC5 is LOW, the minus sign on the LCD panel will not be displayed. And if KEY pin
is floating, the buzzer beeps when the input signal is overflow. The ADP mode function is
summarized below.

Note: Temperature measurement mode takes input signal from ADP pin. In temperature
measurement mode, VBAR pin is used to control the right most digit point on the
LCD panel. When VBAR is LOW, this digit point is displayed.
3. Push function
3.1 HOLD
HOLD mode makes the meter stop updating the LCD panel. This mode can be nested in
most of the special modes. Enabling HOLD function in automatic mode makes the
meter switch to manual mode, but the full scale range remains the same. HOLD function
can be cancelled by changing the measurement mode, pressing RANGE, or push HOLD
again.
