Manual Calibration; Vol.% O Calibration - Dräger Julian Instructions For Use Manual

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 O sensor and zero calibration of the
2
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:
»O -sensor
2
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 O
trations, an additional 100 vol% O
linearity test of the O sensor can be performed under
2
the menu option »more«.
Other settings can already be made during the calibration
process.

Use a separate O source, e.g. O
2
O from the Julian breathing system is not suitable, as
2
it still contains traces of anaesthetic gas.
Unscrew the sample line from the Y-piece and place it
in the continuous flow of the O
Turn the rotary knob to select the line
»O -sensor

100 vol.%«
and press to confirm.
Allow the O flow to continue flowing into the sample
2
line.
A tick ( ) appears after the field when calibration is
complete.
Screw the sample line back on to the Y-piece.
