Description

ES251 is an integrated analog-to-digital converter

with 2,000-count LCD, automatic range selection,

and 3V DC power supply. Automatic range

selection is provided for ACV/DCV measurement,

resistance measurement, current measurement,

capacitance measurement, and frequency counter.

Expensive and bulky mechanical range switches

are not required. Other features include relative

value display, offset removing feature for DCA

clamp

mode,

data

holding,

maximum

and

minimum

value

holding,

detection,

diode

measurement,

temperature

measurement,

continuity checking, low battery detection, auto

power off, re-power on, backlight driver, buzzer

driver and RS232 data output.

Application

 Digital multimeter

 Clamp meter
