Tester detected that one of the
large leads does not have a good
connection.
Tester detected that the large black

MAINTENENCE
IMPORTANT:
Both jaws of each
clamp must firmly engage all
terminals. The copper jaw contains
the smaller gauge wire that reads
the voltage and the silver jaw
contains the larger conducting
wire that draws the load in each
test. Jaw insulation is necessary
for accurate readings. Damaged
clamps or loose wires will affect the
readings. Keep clamps clean and
in good repair.
DO NOT ATTEMPT
TO REPLACE CLAMPS WITH
ANYTHING OTHER THAN AUTO
METER CLAMPS.
CHECK OFTEN FOR LOOSE JAWS
OR DAMAGED INTERNAL PLASTIC
SHOULDER INSULATORS
BATTERY CLAMP REPLACEMENT
Over time the battery clamps will need to be replaced if the following are
indicated:
n
CCA values seem to be way off.
n
If there is continuity between the silver and copper jaw.
n
If there is excessive damage or corrosion to the cables or clamps.
PROCEDURE
n
Disconnect the back cover.
n
Remove the battery to prevent shorting.
n
Disconnect the two small wires from the PC board.
n
Remove the large cables from the copper busses.
n
Carefully pull each wire through the grommets.
n
Reverse the procedure in replacing new clamps.
n
Caution:
Make sure the red clamp wires are attached to the
positive buss and the black clamp is attached to the negative
buss. Putting a little mineral spirits on the new cable ends will
increase ease of insertion through the grommets.
BATTERY REPLACEMENT
When the LCD indicates a low internal battery. Remove the back cover
and replace the battery with a 9 volt Alkaline battery.
