Notes For Using The Instrument - Canon TX-F Operation Manual

2. Notes for Using the Instrument

Before Use
(1) Sudden heating of the room in cold ares will cause condensation to form on the pro-
tective glass in the measurement window and on optical parts inside the instrument. In
this case, wait until condensation disappears before performing measurement.
During Measurement
(1) Before measurement, explain about the measurement that is going to be performed to
the examinee so he/she will not be surprised by a sudden air puff. Demonstrate the
intensity of the air puff by having the examinee place a finger in front of the nozzle
and pressing the
(2) Measurement head automatically moves after the power is turned ON. Do not prevent
movement of measurement head by holding it or placing something near it.
(3) It is recommended that a hard copy of the printout be made if you wish to store it for a
long time, because printouts on thermal paper are apt to deteriorate.
After Use
(1) Turn OFF the power, put the cap over the nozzle in order to prevent dust from attach-
ing to it, and place the dust cover over the instrument.
During Cleaning and Disinfection
(1) If the surface of the objective lens on the nozzle is wiped when dust or dirt is on it, it
will be scratched. Also, do not wipe the objective lens with ethyl alcohol or with
cleaning paper containing silicone. Otherwise, the surface will be corroded, or will be
stained. See section 8.3.2.
(2) Do not use alcohol, benzine or thinner for cleaning the cover of the instrument. Also,
never wipe the cover with ethanol or glutaraldehyde solution. Otherwise, coating will
be corroded. See section 8.3.4.
Environment of Use
(1) After a long time of use, dust in the air will attach not only on the nozzle, but also on
optical parts inside the instrument, which may cause incorrect measurement, Always
keep the room clean.
During Installation
(1) Handle the instrument carefully, as preadjustment may be altered if the instrument
receives a strong jolt.
(2) Do not install the instrument where it will be exposed to direct sunlight. Otherwise, it
will be hard to see the monitor properly, or you may not be able to obtain a correct
measurement.
(3) Blow off the dust in the connectors of the cables with a blower before connecting
them. Otherwise, connection failure may occur.
(4) Do not lay the instrument on its side when the power is turned ON. Otherwise, the
instrument will malfunction.
(5) When the instrument is going to be transported, it must be protected against vibration
and shocks. Contact Canon representative or distributor for advice on the procedure
for packing it.
CLEAR (DEMO) switch for more than 2 seconds.
