If a fault alarm is triggered, determine the cause and take appropriate action.
If the gas detector has problems and is repeatedly malfunctioning, contact RIKEN KEIKI immediately.
NOTE
•
A low flow rate alarm (FAIL LOW FLOW) can be reset by pressing the RESET button. For other
fault alarms, turn off the power and then promptly contact RIKEN KEIKI.
Note that a clock abnormality alarm (FAIL CLOCK) can be reset by pressing the RESET button, but
the internal clock is not operating normally and thus the data logger cannot be recorded normally.
