Description
ES51911 is an integrated analog-to-digital
converter (ADC) with 11,000 counts LCD
display, automatic range selection, and 3V DC
power supply. Automatic range selection is
provided for voltage (AC/DC) 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, zero-offset
removing feature in manual DCA mode for
clampmeter, data holding, maximum and
minimum holding, diode measurement,
temperature measurement, continuity checking,
low battery detection, auto power off, re-power
on, and RS232 data output.
