INSTALLATION
PROPER INSTALLATION IS IMPORTANT. IF YOU NEED ASSISTANCE, CONSULT A CONTRACTOR, ELECTRICIAN
OR TELEVISION ANTENNA INSTALLER (CHECK WITH YOUR LOCAL BUILDING SUPPLY, OR HARDWARE STORE
FOR REFERRALS). TO PROMOTE CONFIDENCE, PERFORM A TRIAL WIRING BEFORE INSTALLATION.

Select a level surface
in an open area above
ground to mount the
collector. Some examples
would be a deck or tree
stump.
Rotate the collector
to remove the cover from
the base. Taped to the base
you will find the necessary
mounting screws to secure the
base to your chosen mounting surface.

RAINWATCH
OPERATION
RAINWATCH has two "counters". They are shown on the face of the instrument as "Current" and "Total".
There are two switches located at the bottom of the case.
The switch closest to the front of the case selects which counter
1
(memory) you wish to display. Regardless of this switch’s
position, both counters are accumulating data.
2
The push button switch closest to the rear of the case is the
reset switch. This switch resets either counter when you desire.
The front toggle switch position determines which memory you
wish to erase.
A. Pushing the select switch to the left and holding the push
button switch for six seconds erases "Current".
B. Pushing the select switch to the right and holding the push
button switch for six seconds erases "Total".
BATTERY MONITOR
If you have installed a 9V battery as per the instructions, the battery
monitor LED will indicate the battery’s condition. Simply, if the LED
is lit, this indicates a good battery.
Upon any power failure the display will go blank and the battery monitor
LED will stay lit. This indicates that the instrument is still collecting and
storing data without interruption. Using a good quality 9V battery,
RAINWATCH can store and collect data for over one week.
NOTE: FREEZING WEATHER WILL NOT DAMAGE THE UNIT,
HOWEVER, READINGS OF SNOW OR FREEZING RAIN WILL
BE INACCURATE.

TROUBLE SHOOTING

If the display is NOT lit check the voltage output from the AC Adaptor. This particular adaptor
puts out between 11 and 15 VAC. If the voltage is not correct then the adaptor is faulty.
If the display IS lit but the unit is not counting then remove the indicator from the wall and
disconnect the collector wires from terminals #4 and #5.
Connect one end of a 3" or 4" long wire to terminal #4.
Reset the "Memories" to 0.
A. Pushing the select switch to the left and holding the push
button switch for six seconds erases "Current".
B. Pushing the select switch to the right and holding the push
button switch for six seconds erases "Total".
5
Using the free end of your test wire, touch terminal #5
and release it. The display should read 00.01.
Repeat step 5 nine more times. The
display should then read 00.10. This
indicates that the instrument is alright
and that the problem lies in the wire
or in the collector.
Contact the factory for advice as to how to troubleshoot

IMPORTANT ADDITIONAL INFORMATION
Components: Along with the indicator, the following components are included with this instrument:
AC Adaptor: This instrument requires its own AC Adaptor. Due to the various power
requirements of each Maximum instrument, attempting to run more than one instrument on a single
adaptor could cause improper operation and/or damage to the instrument(s) thereby voiding your
5-year warranty.
Brass Case: Your brass case is solid brass A70-30 Holloware quality, with a durable lacquer
finish. It is in fact a piece of jewelry and should be treated as such. It should be cleaned at least
once a week to keep airborne pollutants (dust, etc…) and any moisture from collecting on the case
thereby attacking the lacquer. At no time should you use an abrasive cleaner or cloth on the brass
case. Simply use a soft cloth or soft paper towel with a mild glass cleaner to wipe the case clean.
If your instruments are in a summer home, and you are not able to clean them regularly, simply lay
a small cloth or towel across the top two -thirds so that dust cannot settle on the finish.
Specifications: All instrumentation or measuring devices have accuracy tolerances and
specifications. Making comparisons between different pieces of equipment is appropriate provided
the specified accuracies of both are known.
Measurement Range Guaranteed Accuracy
Rainfall (Indicator) 0 to 99.99 Inches of Rain Zero Error (Digital Display System)
Rainfall (Collector) ±.01 Inches/Inch of Rain
