6000 counts LCD display
3V DC power supply
ES51928 is an integrated ADC with 6000 counts
LCD display driver. It could support fully
automatic DMM function measurement. In
voltage or current mode, the AC or DC signals
auto scanning. In R/D/C (passive component)
Conversion rate: 3 times/s (voltage mode)
Full automatic measurement:
*Voltage/Current: AC/DC auto scanning
& auto range: 6.000V~1000V
*Resistance/Diode/Capacitance(RDC scan)
Auto scanning & auto range:
Resistance: 600.0Ω~6.000MΩ
Capacitance: 6.000nF~600.0uF

(including
continuity),
capacitance or diode measurements are allowed
by fully automatic detection. A single key and
simple switch could select all measurements.
Expensive and bulky mechanical range switches
are not required. A non-contact electric field
detector (EF mode) is built-in for ac voltage
measurement also. Other features including
range control, data hold, max/min hold, VAHz
and back light function are available. For power
saving, an auto power off & re-power on scheme
are built-in. A sleep output is the indication of
entering auto power off mode.
