Advanced Functions

F06 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 SETTEMPERATURECOEFFICIENT

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 SETPEUKERTEXPONENT

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 SETDISCHARGEFLOOR

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.
