leaking into the bottle.
4. Leave the unit upside-down in the 33%
salt bottle for at least 40 minutes. The
calibration to 33% is fully automatic and
requires no interaction or checking by
you.
5. Remove the meter from the 33% salt
bottle and again press, hold and release
the
DEW
and
F/C
buttons at the same
time. Doing so this time will cause
_ _ .2
to appear on the lower readout.
6. Turn the unit upside-down and insert the
sensor structure in the opening of the
75% salt bottle after removing the
bottle’s cap. The fit should be tight, with
no air leaking into the bottle.
7. Leave the meter upside-down in the
75% salt bottle for at least 40 minutes.
The calibration to 75% is fully automatic
and requires no interaction or checking
by you.
8. The unit is calibrated when two cycles—
one at 33% and the other at 75%—have
been completed. It is important that the
33% calibration precede the 75%
calibration. Reversing the order, or
performing either calibration twice, will
produce an error message when the unit
is restarted.
