Allows the operator to turn the instrument on and off.
Allows the operator to "mute" the sound of the audible alarm
signal for ± 60 seconds. During this time, a red signal lamp will
flash, indicating a "muted" alarm condition is in force.
Allows the operator to calibrate the instrument to one primary set
point (usually 100%) in accordance with the designated calibration
protocol. This protocol is defined further in this manual and also.
Instructions in abbreviated form can be found on the top of the
monitor casing.
Allows the operator to define a high alarm threshold limit. Range
18% to 102% - if the actual measured value as displayed on the
LCD exceeds this set threshold, an audible and visual alarm
condition will be invoked.
Allows the operator to define a low alarm threshold limit. Range
18% to 100% - if the actual measured value as displayed on the
LCD falls below this set threshold, an audible and visual alarm
condition will be invoked.
Displays measured oxygen concentration, low battery condition
and provides a visual indication of either a high (+) or low (-) alarm
threshold violation.
