• Measurements may be affected by noise or other electromag-
netic ingress if input leads are longer than about three meters.
• Route measurement leads and cables as far away as possible
from power and earth lines.
• Measurement values may be scattered if the leads are routed in
parallel with other devices. If they must be parallel, check opera-
tion before taking measurements.
• Avoid temperature changes around the terminal block. Especially avoid
directed airflow such as from an electric fan or air-conditioner vent.
• If connecting crimped terminals to the analog input terminals, use
insulated terminals for M3 screws with the size shown below.
