MANUALLY SET CEF (Not Recommended)
Allows manual setup of CEF. Displayed as two digits. Default display
A90 indicates automatic CEF recalculation feature active. Returning
to
A90 from a user CEF turns the automatic CEF feature back on. A
user-set CEF will appear as a
UXX in the DATA mode. See page 29.
DEFAULT: A90 RANGE: 65–99 STEP: 1
F07
SET TEMPERATURE COEFFICIENT
Compensates for capacity change with temp. ~ 0.5% Cap/°C. This
coefficient must be supplied by the battery manufacturer. The default
value is typical for lead acid liquid or gelled batteries.
DEFAULT: 0.5 RANGE: 0.1–0.9 STEP: 0.1
F08
SET PEUKERT EXPONENT
Sets exponent for Peukert’s equation. A setting of 1.0 defeats Peukert's
calculation. See pages 39–42 for a discussion of Peukert's equation and
typical values for various batteries.
F09
SET DISCHARGE FLOOR
Sets the discharge floor used to calculate bar graph status and time of
operation remaining functions. The factory default is to calculate time
remaining, and bar graph based on a rate-corrected discharge of 100%
of declared amp-hour capacity. In other words, the bar graph will flash
red when less than 20% of your rate-corrected (Peukert amp hour)
capacity remains. Default time remaining is essentially "time till
dead battery."
To ensure a margin of safety you may wish to set a different discharge
floor. You may wish to set 80% or some other discharge floor for your
bar graph.
