Please set an air switch in the power circuit to isolate the meter from the
main power supply.
Tighten the terminal screws firmly. Tightening torque: 0.5 N.m (5 kgf.cm).
After connecting the power cord, you should connect the power supply to
check whether the meter is normal. Do not connect the signal line before
that, and after confirming that the meter can work normally, disconnect the
power supply and then connect the signal line.
The measurement circuit and the power circuit should be laid separately,
and the measurement object should preferably not be a source of
interference. If this cannot be avoided, please insulate the measurement
object and the measurement circuit and ground the measurement object.
For the interference generated by static electricity, it is better to use
shielded wire.
For interference caused by electromagnetic induction, it is better to
connect the measurement circuit wiring in dense strands at equal
distances.
If the input wiring is connected in parallel with other instruments, the
measured values will be affected by each other. When parallel connection is
necessary, be careful not to switch the power supply of one of the
instruments during operation, as this may have an adverse effect on the
other instruments. RTDs cannot be connected in parallel in principle, and
current signals cannot be connected in parallel in principle.
