ES51961
Description
The ES51961 is a 3 3/4 digits
and bargraph LCD display
measurement system which combines
integrated analog-to-digital converter
(ADC), frequency counter, logic level
tester and OP amplifier, which is
operated with 3V DC power supply.
The ES51961 is suited to voltage,
current, resistance, diode, continuity,
temperature, logic probe and
frequency measurement to 400 MHz.
The frequency counter can
automatically adjust its range to
match the input frequency or manual
setting, over six ranges selectable.
The logic level probe permits
ES51961 to function as a logic probe
and display logic high voltage level
on the LCD display and turn on a
piezoelectric buzzer.
The other functions are provided
for MAX and MIN holding, data
holding, peak data holding, relative
data, low battery detection, backlight,
zoom, reset, range, auto-power-off ,
re-power-on circuit and RS232 data
output.
