Dräger Julian - Manual Calibration; Vol.% O Calibration

Configuring in Standby Mode
Manual calibration

Manual calibration
Julian calibrates its sensors automatically during opera-
tion. The message CAL appears instead of the current
measured value during a calibration process.
Calibration of the O2 sensor and zero calibration of the
other gas sensors can be repeated manually, for instance
if automatic calibration was unsuccessful.
In standby / configuration mode:
● Turn the rotary knob to select the »calibration«
column and press to confirm.
● Select and confirm the appropriate line with the rotary
knob, for example:
»O2-sensor
21 vol.%«
The calibration process is started when the selection is
confirmed. The clock symbol Uappears after the relevant
line, i.e. calibration is in progress.
When calibration is complete, a tick (✓) appears instead
of the clock symbol. A question mark (?) indicates that
calibration must be repeated because the previous
calibration was defective.
To improve the measuring accuracy of high O2 concen-
trations, an additional 100 vol% O2 calibration and a
linearity test of the O2 sensor can be performed under
the menu option »more«.
Other settings can already be made during the calibration
process.
100 Vol.% O2 calibration
● Use a separate O2 source, e.g. O2 flowmeter.
O2 from the Julian breathing system is not suitable, as
it still contains traces of anaesthetic gas.
● Unscrew the sample line from the Y-piece and place it
in the continuous flow of the O2 source.
● Turn the rotary knob to select the line
»O2-sensor
100 vol.%«
and press to confirm.
● Allow the O2 flow to continue flowing into the sample
line.
A tick (✓) appears after the field when calibration is
complete.
● Screw the sample line back on to the Y-piece.
