•Rotary or push re-power on function

•Data hold function

•Low battery detect (3V & 9V)

•On chip buzzer driver

•3V DC power supply

Automatic range selection is provided

for voltage (AC/DC) measurement, ohm

measurement, current(uA and mA)

measurement, and frequency counter. The

ES51977 also provides serial data output

function.

Expensive and bulky mechanical range

switches are not required. The other

functions are provided for data holding,

low battery detection, auto-power-off,

diode measurement, continuity checking.

If non_AC mode , OP will become unit

gain buffer.

•Serial Data Output(RS232 format)

•LCD segment check

•100 Pin flat-package
