Synchronizing the Link 1000 to the Battery
When the battery is fully charged, the Link 1000 displays 0
Ah. This indicates that no energy has been removed from the
battery. (The display can also show a positive number; this
changes to 0 as soon as you place a load on the battery. See
page 45 for details about over-charge Ah).
As the battery discharges, the display shows how much
energy has been used. For example, when you run a 10 amp
load for one hour, the display shows –10 to indicate that 10
Ah have been used.
In other words, the Ah display tells you how much energy has
been removed from the battery as long as the Link 1000 is
synchronized with the battery.
• If you install the Link 1000 on a fully charged battery, it
is automatically synchronized to the battery.
• If you install the Link on a battery that is partially
charged, you must synchronize the Link by following the
procedure given here.
• Once the Link 1000 is synchronized, it stays
synchronized as the battery runs through discharge /
charge cycles. If the Link every gets out of sync with the
battery (this rarely happens), you can synchronize it once
again by following the procedure given here.
To synchronize the Link 1000 to the battery:
1. Discharge the battery by at least 10% of its declared
capacity.
2. Set the Ah reading to 0 by:
a) Holding down
SET until SEL appears in the display.
b) Pressing
SET five times until the RESET LED comes
on and AH appears.
c) Pressing
SET until ALL appears. (Be sure to release
SET as soon as ALL appears.)
4. Charge the battery until the green
FLOAT LED comes on.
(For battery charging procedures, see page 40.)
Overcharge Ah are displayed as a positive number. When
the battery starts to discharge, the Link resets Ah to zero.
