This series digital panel meter adopts digital
electronic measuring instrument,with advanced
circuit design and convenient installation,it
can be directly mounted on the panel of instrument,with
precise accuracy.It can directly measur AC &
DC voltage and current,Frequency,power. |
 |
Working principle:
This meter adopts interference resistance and
strong steady A/D convertion technique,uses large
scale CMOS integrated circuit and converts the
measured analogue signal into digital output showed
by LED displays. |
| The main parts:double integration analogue digital
converter,BCD seven-position decoder,display driver,clock,and
reference resource etc. |
Main technical data:
3.5position display(1999 reading)4.5position
display(1999 reading),also can make various grade
input signal voltage according to customers,requirement. |
