Input section
Lower terminals
: Input terminal HI (+ input terminal of 1V-rane )
: Input terminal HI (+ input terminal of 2A-range)
: Input terminal LO (- input terminal)
Make input signal wires as short as possible and keep them away
from other signal wires.
Use two-core shielded cables in locations with a lot of external
noise and connect the external sheaths to the LO side of the signal
source at one point.
If harmonic noise is superimposed on an input signal, use a low-
pass filter at the time of input. However, care must be exercised
depending on the usage conditions because a delay in response
time is caused in time constant.
, : NC terminals
Do not connect anything to the NC terminals.
: Power terminal (DC POWER 0 V)
: Power terminal (DC POWER +V)
The A8000 series panelmeter has no power switch; connecting it to
a power source causes it to be operable immediately.
