ES51961
3 3/4 MANU DMM
Continuity
If the input voltage (VIN+~VIN-) make the bargraph number ≤3, a 2.5
KHz signal will come out from BUZOUT pin.
Diode
If the input voltage (VIN+~VIN-) high resolution counts ≥2000, the LCD
will display “OL” and no overflow beep exist. If the bargraph number ≤3, a 2.5
KHz signal will come out from BUZOUT pin.

*1: If HOLD function is enabled, then MAX/MIN, REL, PEAK function is
disabled.
*2: If PEAK function is enabled, then REL, MAX/MIN function is disabled,
but HOLD function still can be actived.
*3: If MAX/MIN function is enabled, then REL, PEAK function is disabled,
but HOLD function still can be actived.

*1: If continue to press the HOLD pin (logic low) then power on the
ES51961, and release it in 1.2 sec, the all segments will bright until
pressing the HOLD pin again.
*2: Every time this RESET pin pulse to low (0.8~1.6ms), the pushed
function (HOLD, MAX/MIN, REL, PEAK, ZOOM except BKLIT),
auto-power-off function and counter will be reset.
