Calibration Data In
Probe It should be stressed that the calibration data for the probe are located in
the transducer itself and are loaded from the probe into the instrument’s
memory immediately after power-on (“Loading from headset...”).
Probe Replacement This means that any replacement of probe assembly does not require
any lengthy calibration procedure, but simply a power-on after the new
transducer has been connected. The probe assembly may easily be de-
tached from the instrument by detaching the connector from the rear
panel.
Avoid Detaching
Transducer From
Cable!
However, the practise of repeatedly detaching the transducer from the
cable is not recommended since this could affect the integrity of the air
pressure system.
WARNING!
ZODIAC 901 must be powered off BEFORE disconnecting either
transducer or transducer cable.
3.5.1 EARTIPS
Eartips The ZODIAC 901 is supplied with a set of different sized soft plastic ear-
tips (also called “probe tips” or “probe cuffs”) which fit over the end of
the probe and permit an airtight seal in the patient’s ear canal.
Sanitization Of
Eartips Each tip should be used on only one patient, and then sanitized by
washing in warm soapy water. Eartips should then be rinsed and al-
lowed to dry before reuse. Each tip has a limited life and should be dis-
carded once it becomes difficult to achieve a reliable seal.
Probe tips from other manufacturers may fit the ZODIAC 901 probe, but
they have not been tested by Madsen Electronics and we therefore can-
not make any recommendation regarding their use.
3.5.2 USING THE HEADSET AND PROBE
The ZODIAC 901 probe is designed to provide the user with a choice of
three ways in which it may be supported in use:
·
The transducer may be mounted on the headset. Dimples on opposite
sides of the transducer engage in a pair of lugs on the saddle- shaped
clip on top of the headset. The transducer cable should be pressed into
the clip provided for it on top of the headset. The miniature jack plug
connecting the TDH 39 earphone may be plugged into the socket on the
side of the transducer. The probe itself is connected to the transducer
by three fine plastic flexible tubes. If the probe is attached to the trans-
ducer, slide the small slotted cover in the end of the transducer
upwards, and gently pull the probe out. Take care not to pull the tubes.
