SETTING PEUKERT EXPONENT
When you select Battery Type (See Function F02 on Page 20), your
Link 20
automati-
cally sets a Peukert exponent which is generally correct. However, your batteries may
have different characteristics than "average" and you may wish to change the exponent
so your Time Remaining and Light Bar displays will be as accurate as possible. To
change the Peukert exponent, proceed as follows:
Before you begin, select the Battery you wish to apply the new
exponent to:
BAT 1
or
BAT 2
.

SEL
button.) The right-most green light bar indicator with the legend

under it will
be lit.
C.
Now press and hold the
SET
button. If Battery Type is set to #1 (liquid cells), the
default value of 1.25 (or the previously programmed value) will appear in the display. If
Battery Type #2 (gel cells) is selected, the default value of 1.11 (or the previously pro-
grammed value) will be displayed. The range of values is from 1.0 to 1.50.
Holding down the
SET
button will cause the display to increment in 0.01 steps, after
four increments the display scrolls faster. When the value you want appears, release the
SET
button. If you overshoot your capacity you will have to scroll all the way to 1.50
after which the display will roll over to 1.00 and continue incrementing up.
D.
After 10 seconds, if no keys are pressed, the
Link 20
exits the Setup mode and
the selected value is stored as the new Peukert's exponent and the display returns to
(volts).
