excessively high/low The vaporizer liquid level is
below the minimum mark. Fill the vaporizer.
The control dial is set to “0”. Set the control dial to ≥ 0.2 vol.%.
No vaporizer is connected;
Or several vaporizers are
connected, but unintended
vaporizer is switched on. Connect the vaporizer;
Or switch off the unintended
vaporizer.
The vaporizer is tilted during or
before operation when the control
dial is not at “0”. If this has
happened, liquid anesthetic agent
may have entered the flow control
system. Before operation: flush the vaporizer
with fresh gas. See sections
4.3
Draining the Vaporizer
and

Blowing off the Vaporizer
. Then
check the concentration. See section
8.3 Checking the Concentration
.
Leak, for example, plug-in
adapter is not fitted flush on seals. Disconnect the vaporizer. Check
plug-in adapter safety locking device
and sealing rings. Have them
repaired by trained service personnel
if damage is found.
Valves in the anesthesia machine
plug-in connectors are damaged.
Repair by trained service personnel.
The vaporizer temperature is
outside the specified application
range, such as filled with very
cold anesthetic agent, or operated
with both flow and concentration
high over a prolonged period. Allow the vaporizer to reach normal
temperature, allowing at least 15 min
per
℃ deviation from the specified
range. See section

Temperature
. Refill with anesthetic
agent at room temperature.
The vaporizer is operated with
carrier gas other than air. Change the concentration because of
carrier gas. See section
11.5
Influence of Gas Composition.
The monitor displays volume
percentage, not partial pressure. Convert the measured value to
partial pressure. See section
8.3
Checking the Concentration
.
The vaporizer or anesthetic
monitor is defective. Check with another vaporizer to
establish whether the vaporizer or
anesthetic monitor is faulty. Repair
by trained service personnel if the
