Question
What steps can be taken to reduce noise?
Answer
1. Noise Countermeasures
Do not install the Digital Panel Meter near devices that produce surges or
high-frequency noise.
Mount a surge suppressor or noise filter to peripheral devices that
generate noise, especially devices with a high inductance, such as motors,
transformers, solenoids, and magnet coils.
In order to prevent inductive noise, wire the lines connected to the
terminal block separately from power lines carrying high voltages or
currents. Do not wire in parallel with or in the same cable as power
lines. Other measures for reducing noise include running lines along
separate ducts and using shielded lines.
If a noise filter is used for the power supply, check the voltage and
current, and install the noise filter as close to the product as possible.
2. Analog Signal Input
Applicable Model:
K3HB-X,
K3HB-V,
K3HB-S,
K3GN,
K3MA-J,
K3TE,
K3TF
3. Temperature Input
To prevent the effects of inductance in the lead wires between the
Temperature Sensor and Digital Panel Meter, wire leads separately from
power lines or load lines.
Reception interference may occur if the product is used too close to a
radio, television, or wireless device.
Applicable Model:
K3HB-H,
K3MA-L
