Description
ES51922 is an integrated analog-to-digital
converter (ADC) with 22,000 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 peak detection with calibration mode,
relative value display, Zero function, 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.

*Note: A multimeter with filtered measurement mode is a filed US patent. To avoid the patent infringement, produce a DMM with
low pass filter mode is prohibited to export to USA. Keep the pin55 floating could make LPF mode disable.
