Manual Calibration
Julian calibrates its sensors automatically during
operation. The message CAL appears instead of the
current measured value during the calibration process.
Calibration of the O
2
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 dial knob to select »calibration« column,
press to confirm.
●
Select and confirm appropriate line with dial knob,
for example:
»O
2
-sensor
21 vol.%«
The calibration process is started when the selection
is confirmed. The clock symbol
U appears at the end
of the respective line, indicating that calibration is in
progress.
When calibration is complete, a tick mark (
✓
) appears
instead of the clock symbol. A question mark (?)
indicates that calibration must be repeated because
the previous calibration was not completed success-
fully.
To further improve measuring accuracy of high O
2
concentrations, an additional 100 vol% O
2
calibration
and a linearity test of the O
2
sensor can be performed
under the »more« menu option.
Other settings can already be made while calibration
is in progress.
100 Vol.% O
2
Calibration
●
Use a separate O
2
source, e.g. O
2
flowmeter.
O
2
from the Julian breathing system is not suitable, as
it will still contains traces of anesthetic gas.
●
Unscrew sample line from the Y-piece and place it in
the continuous flow of the O
2
source.
●
Turn dial knob to select the choice
»O
2
-sensor
100 vol.%«
and press to confirm.
●
Allow continuous flow of O
2
into the sample line.
A check mark (
✓
) appears after the field when
calibration is complete.
●
Screw the sample line back onto the Y-piece.
