5.0 Maintenance and Trouble-Shooting
Each Series 942 Mini Analyst has been designed and constructed to give many years of trouble-free service
in the lab, plant, classroom, or field. They are housed in a tough ABS enclosure which is particularly resistant
to rough handling and chemical attack. Their key pads are completely sealed against accidental spills. Treat
your Mini Analyst as you would any valuable possession. Do not allow dust, fluids, or condensation to enter
the tube well, but if this happens, do not open the instrument, instead hold it upside down and gently wipe
the tube well from below with tissue. Cover the tube well or the entire instrument when it is not in use to
prevent debris from entering the well.
5.1 Automatic Self-Diagnosis
Your model 942 automatically performs self-diagnostic steps each time it is turned on and during each
test -- checking its batteries, analog function, LED Lamp, and Photocell. Aside from its batteries, it contains
no user-servicable parts. If a problem should arise that is not covered by the information below, contact
Customer Service by phone at 941.756.6410 or 800.922.5242, by fax at 941.727.9654, or by E-mail at
service@orbeco.com.
5.2 Replacement of Batteries
The Model 942 will display two warning messages. The first: BATTERIES LOW, is a warning that the
batteries are getting weak. You may still be able to perform several tests by inserting the blank and
continuing as before. BATTERIES LOW will continue to appear at the end of each subsequent test until
either fresh batteries are installed, or the batteries continue to weaken to the point that the message
BATTERIES DEAD appears (or the screen remains blank). In this event no further testing can be performed
unless the batteries are replaced.
To replace the batteries, turn instrument over, place thumb on mark on battery compartment cover, press
down and slide the cover off. Replace all 3 batteries, following polarity markings shown in battery
compartment. IMPORTANT: Rechargeable batteries may be used but cannot be recharged in the instru-
ment.
Do not use a mixture of different battery brands. Do not mix regular batteries with rechargeable ones.
5.3 Instrument Not Working?
If your Model 942 is not operating at all, or not operating correctly, first review the below points. (If it
functions correctly, but the results appear wrong, see section 5.4 below).
Check (with a battery checker, not a voltmeter) that each battery has a 1.3v output and that they
have been installed with the correct polarity as shown in the battery compartment. Has BLANK
tube and SAMPLE tube been filled all the way to the 10mL mark? Are tubes free of obstructions
such as bubbles or identifying labels? Outside surfaces of tubes must be unobstructed.
5.4 When Test Results are in Question
If the instrument itself seems to be functioning correctly, but the test results seem to be wrong, first
thoroughly review the contents of these directions, and the following:
