DISPLAY AMP HOURS OR KILOWATT HOURS
DEFAULT OFF = Ah DISPLAY MODE
ON = kWh DISPLAY MODE
When this function is selected the Ah 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 kWh. This counter counts down during discharge and the kWh
consumed are displayed as a negative number. During charging it counts back up with 100%
efficiency. CEF recalculation is prevented until the kWh counter is a positive number. This
prevents premature CEF recalculation and Ah 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 amp
hours from one (or more) charging source(s). The BAT 2 Ah display will count up to 1999
and then roll over to 0 and continue to count up. This is the total number of amp hours
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 five minutes to one 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 setup of CEF (Charge Efficiency Factor). Default display A95
indicates automatic CEF recalculation feature. Returning to A95 from a user declared CEF
turns the automatic CEF feature back on. If a user-setup CEF has been selected it will appear
as a Uxx in the DATA mode.
