Maintenance
This instrument requires no regular maintenance beyond routine
cleaning and annual calibration. The probe tube requires replacement
only when it becomes clogged.
A defective product should not be used. Make sure all connections to
external accessories are snug and secured properly. Parts which may
be broken or missing or are visibly worn, distorted or contaminated
should be replaced immediately with clean, genuine replacement
parts manufactured by or available from GSI.
Equipment is not user repairable. Repairs and battery replacement
must be performed by a qualified service representative only.
Annual calibration is recommended. A Due for Service screen will
appear once daily after 1 year has elapsed from the calibration date.
Have an authorized service technician perform electrical safety
checks on the unit in order to maintain continued compliance to IEC
and UL 60601-1.
Probe tube Replacement
Probe tubes are disposable and should be replaced when they become
clogged. Replacement probe tubes are included with this instrument.
Do not attempt to clean the probe tube.
To replace the probe tube, use the eartip to grasp the probe tube (the
clear plastic tube) and twist slightly while pulling the probe tube
straight out of the probe head (Figure 4). Dispose of the used probe
tube immediately to avoid confusing used tubes and new tubes. Take
a new probe tube from the package and insert the tube into the probe
head until it is fully seated (Figure 5). A properly inserted probe tube
will snap securely into place when it is fully seated in the probe head.
DO NOT ATTEMPT TO CLEAN PROBE TUBES.
THIS MAY CAUSE DAMAGE TO THE PROBE.
