General description
ES269 is an integrated ADC with 6,000 counts
LCD display driver. It could support fully
automatic DMM function measurement. Voltage,
current,
resistance
(including
continuity),
capacitance or diode measurements are allowed
by fully automatic detection. A non-contact
electric field detector (EF function) is built-in for
ac voltage measurement also. Other features
including data hold, peak 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.
