Replacing the Batteries
The battery compartment in the base of the instrument is secured by four
screws. To replace the batteries, remove the cover and install the batteries,
observing the correct polarity as indicated. Use three of the same brand x
1.5V 'AA’ alkaline batteries or equivalent.
To avoid corrosion damage through leakage, remove batteries from the
instrument if it is to be stored or left unused for a long period of time.
Cleaning the Optics
Any build-up of dirt or deposits may interrupt light transmission and affect
readings.
To clean the optics, undo the two screws to remove the optics base plate.
Gently clean the internal surfaces of the optics with a soft, non-abrasive
cloth. Deposits may be removed with a slightly dampened cotton bud.
Replace the optics base plate and re-fasten the screws.
The photometer is fitted with long-life light sources and contains no user-
serviceable components. If the instrument requires servicing or repair, this can
be arranged through our Technical Services Department.
Service Requirement
Servicing of photometer instruments is essential to ensure optimum
performance. To arrange a service of the instrument, contact your local
distributor who supplied the instrument. The Palintest standard photometer
service includes cleaning of the optical assembly, replacement of any worn
parts and checking/ recalibration of the instrument.
