4. Perform Test
4.1 Test Preparations
!If performing the battery test in a vehicle, ensure
that
$all additional loads are deactivated,
$the key is not in the ignition,
$all doors are closed,
$measuring is not carried out by or with steel
bolts.
iBefore connecting the tester, clean the battery posts
or side terminals with a wire brush and a mixture of
baking soda and water.
4.2 Connecting BAT 131
!For a proper connection, rock the clamps back and
forth. The tester requires that both sides of each
clamp be firmly connected before testing. A poor
connection will produce a CHECK CONNECTION or
WIGGLE CLAMPS message. If the message appears,
clean the terminals and reconnect the clamps.
iThe preferred test position is at the battery termi-
nals. If the battery is not accessible, you may test at
the jumper post; however, the available power mea-
surement may be lower than the actual value.
4.2.1 Directly on battery posts (TOP POST)
1. Connect the red clamp directly to the positive post
(+).
2. Connect the black clamp directly to the negative
post (–).
4.2.2 On side battery posts via lead post adapter
(SIDE POST)
!Test results will be inaccurate, if there is no
$lead post adapter or
$worn or dirty lead post adapters are used.
!Tighten the lead post adapter with an adjustable
wrench by a max. of ¼ turn.
1. Connect the red clamp via the lead post adapter (availa-
ble from specialist stores) on the side positive post (+).
2. Connect the black clamp via the lead post adapter
(available from specialist stores) on the side negati-
ve post (–).
4.2.3 On jump-start posts (JUMP START POST)
1. Connect the red clamp to the positive jump-start
post (+).
2. Connect the black clamp to the negative jump-start
post (–).
