(1) PW/TR light is not ON. (Power is not supplied.)
・Is it OK with power cable connection ?
Connect power cable.
・Is fuse disconnected ?
Search the cause of disconnection and replace it after making counter-measures.
・Is power voltage normal ?
Supply the rated power voltage.
・Is this power switch turned on ?

take an appropriate action for noise.
(3) No calibration available
・Is the concentration of calibration gas correct ?
Prepare the appropriate calibration gas.
・There is the possibility for decreasing of sensor sensitivity.
The sensor replacement is required.
(4) PW/TR light flashing.
① System Trouble “E-00”
・Memory trouble inside of detector.
Contact our nearest agent or Riken Keiki.
② Sensor connection trouble “E-01”
・Non-connection of sensor, contact failure of connector and disconnection of sensor cable.
Check “whether sensor is connected” or “the sensor cable connector is connected to the
sensor or amplifier board. ”
If can not be recovered, contact our nearest agent or Riken Keiki.
③ Abnormal function for zero correction 「E-04」
・Zero correction was out of available range due to sensor drift.
Contact our nearest agent or RIKEN KEIKI.
④ Low flow trouble “E-05”
・Drop of pump function
Even though the ball of flowmonitor can not be up the red line(lower red line) with FLOW
ADJ/▲▼switch, replace the pump with new one.
・Check that the detector unit is mounted firmly or the fixing screw of detector unit is
