IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS. The safety information contained herein should be
reviewed every time the unit is used.
BATTERY SAFETY:
ALWAYS WEAR EYE PROTECTION WHEN WORKING NEAR A
BATTERY.
CAUTION:
The electrolyte in automotive batteries is
sulfuric acid, which is capable of causing severe damage to skin,
eyes, and clothing. When contact with battery acid occurs, proceed
as follows:
1) Eyes: Force open and flood with cool running water at
least for 10 minutes, then see a doctor. Never use eye
drops or other medication before seeing a doctor.
2) Remove contaminated clothing and flood skin for at least
10 minutes with clear, cool water.
While batteries are being charged or tested, an explosive gas
mixture forms inside each cell. Some of this gas escape through the
vent holes in the filler caps and may remain around the battery in an
explosive condition. Sparks or flames igniting this gas mixture will
burn back through the vent hole and explode inside the battery cell.
Such an explosion is dangerous not only because of its own force,
but also because of the acid electrolyte which could spray onto
anything in the vicinity.
TO PREVENT EXPLOSIONS:
1) Use well ventilated areas for charging and testing batteries.
2) Allow no smoking, sparks or open flames near batteries being
charged, tested or batteries recently charged or tested.
3) Do not break live electrical circuits at the terminals of batteries
because a spark may occur at that point causing an explosion.
Always turn battery chargers or tester OFF before connecting
or disconnecting the clamps from the battery terminals.
PERSONAL PRECAUTIONS:
1) Wear complete protection and avoid touching eyes while
working near battery.
2) NEVER smoke or allow a spark or flame in the vicinity of
battery or engine.
3) Be extra cautious to reduce risk of dropping a metal tool onto a
battery. The tool may spark or short-circuit the battery or other
electrical parts which may cause an explosion.
4) Remove personal metal items such as rings, bracelets,
necklaces, and watches when working with a lead-acid battery.
A lead-acid battery can produce a short-circuit current high
enough to instantly weld a ring or the like to metal, and cause
severe burn.
5) Spilled acid: Neutralize with a solution of baking soda (1 pound
per gallon of cold water) or household ammonia (1 pint per
gallon of cold water)
VEHICLE SAFETY:
1) Keep your body, clothing, and test leads away from all moving
parts of the vehicle. Remember, electric fans may start at any
time.
2) Avoid hot engine parts.
3) Engine exhaust contains deadly carbon monoxide gas. Run
engine only in a well ventilated area with exhaust gases
ventilated outdoors.
4) When running engine tests, be sure that the vehicle is in "park"
or "neutral" and the parking brake is on when starting the
vehicle. Block wheels to prevent vehicle movement.
5) When disabling the ignition system to run starter tests, always
refer to vehicle service manual for proper procedure.
6) Do not connect any test lead to carburetor, fuel lines, or sheet
metal parts of frame.
TESTER PRECAUTIONS AND NOTES:
1) Always be sure LOAD ADJUST knob is in full counter
clockwise position when disconnecting or connecting heavy
duty leads to prevent arcing.
2) Never block ventilating holes on the top or the bottom of the
unit. This will shorten the carbon pile life.
3) STEAM AND ODORS MAY BE RELEASED FROM CARBON
PILE LOAD ASSEMBLY ANYTIME IT IS USED. THE
CARBON DISCS ABSORB MOISTURE AND ODORS AS
WOULD AN ACTIVATED CARBON FILTER, THESE ARE
RELEASED WHEN THE CARBONS ARE HEATED.
4) A duty cycle is hard to define for a carbon pile load assembly.
Size of load, length of test, time between tests, ambient
temperature, and other factors affect the duty cycle. For the
longest life, never let the carbon discs get red hot. This can be
easily seen when running the load test. If the discs get red hot,
the binder material holding the carbon granules together will
start to deteriorate and lead to shortened disc life.
5) For the ammeter to read +amps, attach current probe so arrow
on probe points in direction of current flow (from positive to
negative).
6) Residual magnetism in the AMPS PICKUP may cause it to
indicate a low current even if there is no current flow. This is a
normal situation. Therefore, the AMPS meter has to be zeroed
before each use. This can be done with the AMPS ZERO
ADJUST knob.
7) In the booklet, the word "positive" refers to the red clamp or
lead. The word "negative" refers to the black clamp or lead.
8) "Positive" when referring to a battery terminal will mean the one
marked Pos, P, (+).
9) "Negative" when referring to a battery terminal will mean the
one marked Neg, N, and (-).
10) PLEASE NOTE THAT THE DEFECTIVE DIODE LIGHT MAY
FLASH ON AND OFF DURING SOME OF THE TESTS
DESCRIBED. THIS IS NORMAL AND SHOULD NOT BE
CONSTRUED TO BE A PROBLEM WITH THE UNIT.
11) During a load test, the light gauge leads may be used to read
voltage across Battery 1, cable jumper, and Battery 2. These
can be added up to give the total system voltage. This total
may not be the same as read by the voltmeter on INT position
with the clamps installed as shown. This may be caused by
corrosion on terminals, rounding off by the voltmeter circuit, or
other factors and does not mean there is a problem with the
unit.
The components in the AMPS PICKUP are somewhat temperature
sensitive. As it warms near a hot engine or cools when exposed to
outdoor air, the zero on the AMPS meter may drift. Once the pickup
has stabilized, the zero will not drift.
