Low and High Oxygen Level Alarm
The SAN-102 is equipped with audible and visual alarms to alert you when the ambient oxygen
concentration exceeds either of the two factory preset alarm levels:
•
Danger Low Oxygen Alarm:
19.5% - LED will flash and audible alarm will sound 3x / sec.
•
Warning High Oxygen Alarm:
23.5% - LED will flash and audible alarm will sound 2x / sec.
Normal atmosphere contains between 20.8% and 21% oxygen. OSHA defines any atmosphere
that contains less than 19.5% oxygen as “oxygen deficient” and any atmosphere that contains
more than 23.5 percent oxygen as “oxygen enriched.” These levels are factory set and cannot
be changed.
Fahrenheit and Celsius Switching
•
Press the °F/°C button to switch between the two temperature units.
•
Press the Power button briefly to save the temperature setting and return to normal display.
Low Battery Alarm
The meter continuously measures the rechargeable battery’s voltage. If it drops to a critical
level, the low battery alarm will sound until the battery is recharged or the battery power is
depleted.
Note that the meter can continue to monitor oxygen levels while charging.
CLEANING AND STORAGE
The front panel and case can be cleaned with a mild solution of detergent and water. Apply
sparingly with a soft cloth and allow drying completely before using. Do not use aromatic
hydrocarbons or chlorinated solvents for cleaning.
ATTENTION! - If a Warning or Danger alarm is triggered
while using the instrument as a safety monitor, leave
the area and seek fresh air immediately. Remaining on
site under such circumstances can cause serious
impairment or even lead to death.
Calibration
The SAN-102 comes pre-calibrated from the factory
.
However, the O2 sensor should be
calibrated at least once a year, or as described in your company's safety procedures. You can
perform the calibration yourself, or you can return it to CO2Meter for factory calibration at a
nominal fee.
SAN-102 can be atmospherically calibrated. By pressing the
Fahrenheit and Celsius
switching button
for 4 seconds, the monitor will enter O2 atmospherically calibration mode.
While in calibration mode, press the
Fahrenheit and Celsius switching button
quickly to
switch between atmospherically calibration or Exit. Press the
Power button
to confirm.
The atmospherically calibration will not require additional materials but must be performed in
outdoor (fresh air) during the entire procedure.
The temperature and humidity sensors do not require calibration and should remain accurate
for the life of your unit.
