6 Instruction 19-9208
To start a new TWA reading after the monitor has been turned ON, press
and hold down the f1 button for 3 seconds or more until the following display
appears:
Confirm that a new TWA is reading is desired by pressing and holding
down the f2 button for 3 seconds or more. The message “New TWA
Started” will appear while the f2 button is held down. Otherwise, press
the f1 button to cancel this operation and return to the existing TWA.
2.6 TWA Alarm
The 3010 Monitor has a built-in TWA alarm whose trip-point is based
upon the selected TWA format (either 8 hours or continuous). The alarm
level, however, is supplied from the factory preset to zero (no alarm), but
can be activated by using the optional BACH-COM software. When the
alarm is tripped, the monitor emits a beeping tone that remains on until
the TWA level falls below its trip point. The alarm can be manually
turned OFF by pressing the f2 button which starts a new TWA reading, or
the alarm can be turned OFF by simply switching OFF the monitor.
2.7 Auto-Stablization Mode
This mode automatically corrects for any drift when taking TWA read-
ings. Auto-stabilization will effectively remove any effect of drift over
periods of many days.
Before entering the auto-stablization mode, first zero the monitor per
Section 3.8 Zero Calibration, and, if necessary, select the TWA mode by
pressing the f1 button.
Enter the auto-stabilization mode by simply attaching the supplied
restrictor (Figure 1, Item C) to the monitor’s gas outlet (Figure 1, Item D),
and then turning ON the pump by pressing the f3 button. The monitor
will automatically detect the presence of the restrictor and enter the auto-
stablization mode.
Important! Use only the supplied restrictor, which has been
specially calibrated to work with the monitor.
