NOTE
•
When powering on after leaving the detector for more than five minutes with the batteries removed,
such as when powering on for the first time, replacing the batteries, etc., or powering on with the
batteries inserted with incorrect polarities, a clock abnormality (FAIL CLOCK) may be triggered.
When it is reset using the MODE button, the detector moves to the date/time setting screen. See
"6-2. Date/time setting" on page 31 and set the date/time.
•
Warm-up time (WARM UP) is different depending on the stability status of the sensor.
•
If the detector is not used for a long period, warm-up time may be longer or a sensor abnormality
(FAIL SENSOR) may be displayed. In such a case, restart the detector.
•
The detector performs air calibration automatically during start-up. If an environment where the
detector is turned on is different from the atmosphere being measured, perform air calibration again
in the measured atmosphere.
