SELECT RAIN GAUGE INCREMENTS AND RAINFALL UNITS
If your
ULTIMETER
system does not yet include a self-emptying rain
gauge, you may skip this section and proceed to "DISPLAYING
CURRENT DATA".
Use the procedure below to tell the instrument the measuring increment
of your rain gauge. Allowable rainfall increments are: 0.01 inches, 0.25
mm, 0.1 inches, 0.1 mm, and 2.5 mm.
1. Press and release the
key. The rain icon and "0.00 in" will
appear in the display. Each time your rain gauge reports an
increment of rain, the rain display will increase by 0.01 inches. If
your rain gauge reports rainfall in increments of 0.01 inches, skip
the rest of this section.
2. Press and hold the
key a second time until the display
stops flashing. "0.00 mm" will appear in the display. Each time
your rain gauge reports an increment of rain, the rain display will
increase by 0.25 mm. If your rain gauge reports rainfall in
increments of 0.25 mm, skip the rest of this section.
3. Press and hold the
key a third time until the display stops
flashing. "0.0 in" will appear in the display. Each time your rain
gauge reports an increment of rain, the rain display will increase by
0.1 inches. If your rain gauge reports rainfall in increments of 0.1
inches, skip the rest of this section.
4. Press and hold the
key a fourth time until the display stops
flashing. "0.0 mm" will appear in the display, with the "mm" flashing.
Each time your rain gauge reports an increment of rain, the rain
display will increase by 0.1 mm. If your rain gauge reports rainfall in
increments of 0.1 mm, skip the rest of this section.
Note to Serial Data Port Users: when you select 0.1mm
increments, the serial data output will report rain totals in metric
rather than English units.
5. Press and hold the
key a fifth time until the display stops
flashing. "0.0 mm" will appear in the display, with the "mm" not
flashing. Each time your rain gauge reports an increment of rain,
the rain display will increase by 2.5 mm. If your rain gauge reports
rainfall in increments of 2.5 mm, this is the correct setting.
INITIALIZE THE LONG-TERM RAINFALL TOTAL
Press and release the
key. Then press and release the
key eight times to display the long-term rainfall. Press and hold
28
for at least three seconds. The display will flash three times,
then stop. The Long Term rainfall total will be reset to today's
rainfall, and the rainfall "since" date will be reset to the current date.
Or, to reset ALL long-term memories (including rainfall), press and
hold
and
simultaneously for at least three seconds. The
display will flash three times, then stop. All Long Term high and low
values will be replaced by the current values, the Long Term rainfall
total will be reset to today's rainfall, and the rainfall "since" date will
be reset to the current date. You may wish to use this "master
reset" procedure on the first day of each new month.
