Caution on cable connection and instruction
(1) Confirm “+” and “–” polarity first. If the polarity is opposite, sensor cannot operate.
(2) Do not supply power voltage more than the specification. It will cause breakdown on sensor.
(3) Shield wire (Silver) connect on minus side of power supply.
(4) In case of using any receiver such as logger with 1-
5V, connect 250Ω resistance with it in
parallel.
(5) When relaying cables, be sure to use cable junction box. Also, take measures to prevent
disturbance noise from entering. If noise countermeasures are not implemented, correct
measurement results may not be obtained.
