For interference caused by static electricity, it is better to use shielded wire.
In order to prevent fire, please use double insulated wires (it is recommended to use
wires with a cross-sectional area ≥0.75mmfor the power cord; the relay output wiring
needs to have strong voltage resistance and a wire with a cross-sectional area ≥0.5 mm
When the platinum resistance is input, the resistance of each lead should be less than
10Ω (the lead resistance is the same).
Tighten the terminal screws securely. Tightening torque: 0.5N.m (5kgf.cm).

measurement circuit wiring equidistantly.
To prevent electric shock, please confirm that the power supply has been cut off at the
wiring money.
The measuring circuit and the power circuit should be laid separately. The measuring
object is not the interference source. Once it cannot be avoided, please insulate the
measuring object from the measuring circuit and ground the measuring object.
If the input wiring is connected in parallel with other instruments, it will affect the
measured value. When it is necessary to connect in parallel, it is necessary to pay
attention not to switch the power supply of one of the instruments during operation, as
this will adversely affect other instruments. Thermal resistance cannot be paralleled in
principle, and current signals cannot be paralleled in principle.
Please install an air switch in the power circuit to separate this watch from the main
power supply.
To improve the safety of the instrument, please observe the following warnings
when wiring:
After connecting the power cord, connect the power to check whether the instrument is
normal. Do not connect the signal cable before that. After confirming that the instrument
can work normally, disconnect the power and connect the signal cable.
