9−1 Troubleshooting
Use the procedures described in this chapter when trouble occurs in the operation of the leak detection
system.
If the appropriate troubleshooting does not restore the equipment or the problem is not covered in this
chapter, please contact your agent company.
① If the main unit does not turn on:
● Make sure the battery is inserted.
● Replace the battery with a charged one.
② If the pre-amplifier does not turn on:
● Try charging the battery.
③ If a switch or button on the main unit
does not work:
● Press the switch or button firmly. Pressing the key will
produce a confirmation sound.
④ If the main unit does not receive radio
signals or reception is bad:
● Make sure the pre-amplifier is powered on.
● Make sure the receiving antenna is securely connected to
the main unit.
● Check whether there are buildings etc. between the main
unit and pre-amplifiers. These can block the radio signal
from reaching the main unit. Try to bring the
pre-amplifier closer to the main unit.
● The range of the radio signal is about 100 m in a place
with good visibility. (Distance between main unit and
pre-amplifier)
● Try placing the pre-amplifier antenna in a higher location.
⑤ If the pipe type, pipe diameter, and
pipe length are unknown:
● Use the white noise method to calculate the unknown
parameters.
* For details see "6-3 White Noise Method" on p. 76.
