Minimum Flow Rate Table; Alarms - Quest Technologies SafeLog 100 Operator's Manual

Press the ▼ arrow key on the unit so that the CAL annunciator appears in
the display along with the current gas level. Wait for the level on the unit's
display to stabilize. Press the enter key; "CAL" appears in the display as the
unit calibrates itself.
When the sensor is old and can no longer calibrate, an error message is
given in the display. (See Section 5 "ERROR MESSAGES" on page 21 for
more information.)

3.8.1 Minimum Flow Rate Table:

This chart shows the minimum flow rate necessary for calibration. Be sure
that the proper regulator is used.

Sulphur Dioxide 400
Nitric Oxide 250

3.9 Alarms:

All alarm levels may be set or changed through the setup mode. The unit
uses HI, STEL, and TWA alarms for toxic sensors and HI and LO alarms
for oxygen sensors.
During the run mode, HI and LO alarm conditions are checked each second
and STEL and TWA alarm conditions are checked every minute. If any
alarm setting is exceeded, the buzzer and LED turn on, the value causing
the alarm is displayed, and the alarm condition and time of occurrence are
recorded in memory. Pressing the on/off key will turn off the alarm. If the
alarm condition still exists, it will be turned back on when the alarming
value is next calculated (1 minute for STEL and TWA, 1 second for HI and
LO levels).
Using QuestSuite™ for Windows software, allows a high level pre-alarm to
be set and enabled. If the sensor reading exceeds the pre-alarm level, the
unit gives a once per second chirp. Note that this feature may only be set up
and enabled with QuestSuite™ software.
