 Description
ES239 is an integrated analog-to-digital converter
with 6,000-count LCD with bar-graph display,
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,
duty cycle measurement, diode measurement,
inrush function for clamp-on ACA mode,
temperature measurement, continuity checking,
low battery detection, auto power off, re-power on,
backlight driver, buzzer driver and RS232 data
output.
