4.6.2HIGH ALARM
When a monitored gas concentration reaches the high alarm level setpoint, the instrument emits a continuous dual tone alarm. As with the low alarm condition, the red alarm light bar and backlight will flash simultaneously with the displayed gas value. If the hygiene/datalogging option is installed, the STEL alarm will mimic the high alarm indicator and the STEL display value in alarm will flash.

4.5.11 STEL (Short Term Exposure Limit)*
This mode displays the short term average exposure values of the toxic sensors installed in the instrument.
4.5.12 HYGIENE RESET
This mode allows the user to reset the hygiene session and the STEL and TWA exposure values.
4.6ALARM INDICATORS
4.6.1LOW ALARM
When a monitored gas concentration reaches the low level alarm setpoint, the instrument emits a short beep approximately every 1.2 seconds. The red alarm light bar and backlight will flash simultaneously along with the displayed gas value. If the hygiene/datalogging option is installed, the TWA alarm will mimic the low alarm indicator and the TWA display value in alarm will flash.
NOTE: The ATX612 uses the continuous high alarm tone for both low (depletion) and high (enrichment) oxygen alarm conditions.

4.6.4 COMBUSTIBLE GAS |
|
|
|
|
When the ATX612 detects combustible gases in excess of |
|
|
|
|
100% of LEL (5% CH4 by volume), a high alarm |
|
|
|
|
condition is latched (locked on) and +OR is displayed in |
|
|
|
|
place of the combustible gas reading. Power is removed |
|
|
|
|
from the combustible gas sensor to prevent damage due to |
|
|
|
|
the high level of combustible gas. |
