DISPLAY A HRS OR KWHRS
DEFAULT OFF = A HR DISPLAY MODE
ON = KWHR DISPLAY MODE
When this function is selected the A hr display shows kilowatt hours. Kilowatt hours
are used internally by the Link 20 to determine if 100% of the energy consumed from
a battery returned during charging. A recalculation of the CEF is not permitted unless this
counter is greater than 0.00 kWhr. This counter counts down during discharge and the
kWhrs consumed are displayed as a negative number. During charging it counts back up
with 100% efficiency. CEF recalculation is prevented until the kWhr counter is a positive
number. This prevents premature CEF recalculation and Ahr reset. Kilowatt hours is a
very precise measurement of energy removed from or returned to your battery banks.

ALTERNATIVE ENERGY MODE
DEFAULT: OFF
ON: BATTERY/SOURCE MONITORING MODE
This function selects between the normal two battery monitoring mode and the
battery/source monitoring mode. When this mode is OFF, the meter works as a two battery
monitor as described elsewhere in this manual.
SOURCE MONITORING: When this mode is ON, the BAT 1 position works normally,
showing energy flowing into (or out of) Battery #1. The BAT 2 Volt and Amps displays
report the charging source voltage and current. The BAT 2 Ah display reports cumulative
A hrs from one (or more) charging source(s). The BAT 2 A hr display will count up to 1999
and then roll over to 0 and continue to count up. This is the total number of A hrs supplied
since the meter was powered up (or RESET). You may also use the kilowatt hours display
(see previous function, F04). The BAT 2 Time display will read CCC. The BAT 2 CEF
is set to 100% and is displayed as 100.
CHARGED PARAMETERS: Also, when this mode is ON, the time necessary to meet
the Charged Parameters is reduced from 5 minutes to 1 minute. This is useful if your
alternative energy installation uses solar panels and you have clouds periodically obscuring
the array causing your charging to be intermittent. It's also useful if you're using an ON/OFF
(high-low voltage set point window) controller. If you're using this type of controller, you
may wish to increase Charged Current % to 3 or 4% of Battery Capacity.

MANUALLY SET CEF (Not Recommended)
DEFAULT OFF = AUTO RECALCULATION OF CEF
DISPLAY = A95
RANGE = 65-99 STEP = 1
Allows manual set up of CEF (Charge Efficiency Factor). Default display A95
indicates automatic CEF recalculation feature. Returning to A95 from a user delcared
CEF turns the automatic CEF feature back on. If a user set up CEF has been selected it will
appear as a Uxx in the DATA mode.
