Description
The ES5108 is design for 3 1/2-Digit Digital Multi-
meter which combines an integrated A/D converter,
MAX/MIN, hold, short circuit beeper, low battery de-
tector, a frequency counter, and serial data output.
A ’HOLD’ input allows the ES5108 to hold the cur-
rent A/D readout or frequency readout. The frequency
counter is auto-ranging from 2KHz to 20MHz over a
five decade range with KHz and MHz annunciators.
Short circuit beeper will sound whenever the readout
is less than 30 after enabling the short circuit beeper.
This feature is useful in detecting short circuits without
watching the LCD.
The ES5108 provides 3 independent decimal point driv-
ing pins for the manufacturer to determine which deci-
mal point or unit is display, the 3 decimal point drivers
are built-in ES5108.
