STEL Screen
The STEL Screen displays the short term exposure limit (STEL) readings for
H
2
S and CO only. The STEL reading is the average reading over the last 15
minutes.
TWA Screen
The TWA Screen displays the time weighted average (TWA) readings for
H
2
S and CO only.
The TWA reading is the average reading over the last 8 hours. If 8 hours have
not elapsed since the last time the TWA reading was cleared, the average is
still calculated over 8 hours. The missing time is assigned a 0 value for
readings. If the lunch break feature is turned off, the TWA is cleared when the
EAGLE 2 is turned off.
The lunch break feature enables the EAGLE 2 to remember TWA readings
when it is turned off so it can continue them when it is turned on again. See
“Turning On the EAGLE 2” on page 22
