↑↑
and
↓↓
Keys- The ↑ and ↓ arrow keys are used in
conjunction with the CALIBRATE key to calibrate the unit or in
conjunction with the LOW SET and HIGH SET keys to adjust the alarm
settings. When used after pressing the CALIBRATE key, pressing the ↑
or ↓ key will raise or lower the displayed oxygen value in .1%
increments. When either of these keys are held down for more than 1
second, the display will scroll at a rate of .4% per second. When used
after pressing either the LOW SET or HIGH SET keys, pressing the ↑ or
↓ key will raise or lower the displayed alarm setting in 1% increments. In
the alarm set mode, holding these keys down for more than 1 second
will cause the display to scroll at a rate of 4% per second.
LOW SET Key- When the keypad is unlocked, pressing the
LOW SET key will cause the "LOW" icon to flash. The low
alarm setting can then be changed using the ↑ and ↓ arrow keys. When
the low alarm value is set and the LOW SET or LOCK/UNLOCK key is
pressed again, the unit exits the alarm set mode and returns to normal
operation. The unit will also revert to normal operation (storing the most
recent alarm value) if 10 seconds elapse and no keys are pressed. The
OM-25ME alarm setting is adjustable down to 18%. The OM-25ME-L low
alarm setting is adjustable to 15%.
HIGH SET Key- When the keypad is unlocked, pressing the
HIGH SET key will cause the "HIGH" icon to flash. The high
alarm setting can then be changed using the ↑ and ↓ arrow keys. When
the high alarm value is set and the HIGH SET or LOCK/UNLOCK key is
pressed again, the unit exits the alarm set mode and returns to normal
operation. The unit will also revert to normal operation (storing the most
recent alarm value) if 10 seconds elapse and no keys are pressed.
SILENT Key- In an alarm condition, pressing the SILENT key will
deactivate the alarm beeper, but the alarm LED and display will
continue to flash. In 120 seconds, the alarm beeper will sound again.
This process will be repeated until the alarm condition is cancelled. For
an alarm condition to be cancelled, the concentration must be .1% higher
than the alarm setting (in the presence of a low alarm condition) or .1%
lower than the alarm setting (in the presence of a high alarm condition).
External Probe
Sensor with Diverter- The sensor (with diverter) is designed to fit
industry standard, 15 mm I.D. "T" adapters.
Extendible Cable- The extendible cable allows the sensor to be
positioned up to 10 feet from the side of the unit.
