Low Alarm latch
After confirming that there is no leakage on
site or the alarm is released, please click the
“√” button to “reset” the latch.
High Alarm latch
After confirming that there is no leakage on
site or the alarm is released, please click the
“√” button to “reset” the latch.
TWA alarm
Indicating that the gas cumulative
concentration in 8 hours exceeds the
standard
STEL alarm
Indicating that the gas cumulative
concentration in 15 minutes exceeds the
standard
Overrange alarm
Indicating that the gas concentration
exceeds the range, and the detector returns
to the normal detection mode after the site is
safe.
Low Alarm
Indicating that the gas concentration on site
exceeds the underreportting set value.
High alarm
Indicating that the on-site gas concentration
exceeds the high alarm setting value.
Note: When the detector exceeds the Full-Scale Range, the normal detection
mode is displayed after the on-site gas concentration returns to the normal
range. But for Catalytic Bead sensor, its high working current, long time working
under over-range conditions will lead to sensor damage. The detector will
detect the gas concentration in the environment every 4 minutes until the
ambient gas returns to the normal range, and the detector returns to the normal
detection mode.
