MODEL 6024
DUAL VOLTAGE
BATTERY TESTER
OPERATOR'S MANUAL
WARNING
Batteries produce explosive gases and can explode.
Wear safety goggles. (User and bystanders)
Keep flames and sparks away from batteries.
Read and follow instructions.
Battery explosion and ignited gases can cause injury.
WARNING
Battery acid can cause chemical burns.
Wear protective clothing. (User and bystanders)
Chemical burns can cause injury.
SAFETY INFORMATION
Working in the vicinity of lead-acid battery is DANGEROUS due to EXPLOSIVE
GASES generated by the battery which can be ignited by a spark, cigarette or flame
and blow the battery apart, forcefully showering the area with battery pieces and acid.
To reduce the chance of exploding batteries follow instructions by manufacturers of
batteries as well as these instructions.
IN CASE OF ACCIDENT RINSE EYES WITH CLEAN WATER AT LEAST 5
MINUTES AND SEE A DOCTOR IMMEDIATELY. NEVER USE EYE DROPS OR
OTHER MEDICATION UNLESS DIRECTED BY A DOCTOR.
When around lead-acid batteries wear eye protection and avoid touching or rubbing
the battery as well as clothing, skin and eyes. NEVER smoke, have an open flame or
sparks near battery. Have plenty of ventilation and keep your face as far as possible
from the battery. Undercharged lead-acid batteries will freeze during cold weather.
Never test or charge a frozen battery. Do not allow tools to drop onto a battery. Do
not lay tester on battery.
BATTERY LOAD TEST
This test evaluates the battery's ability to crank an engine. The tester draws current
from the battery while measuring its voltage level. The voltage level of a good battery
will remain relatively steady under load, but a defective battery will show a rapid loss
in voltage. Battery size (CCA rating) and temperature will affect test results - follow
instructions carefully.
1
1. Turn off engine, accessories and battery test equipment.
2. Connect negative (black) clamp to the negative (NEG, N,-) battery post. Connect
positive (red) clamp to positive (POS, P, +) battery post. "Rock" clamps back and
forth to insure a good electrical connection. For batteries with side terminals, use the
adapters in clamps.
3. With clamps connected, tester's meter will indicate battery's STATE OF
CHARGE. If state of charge is less then 12.4 (24.8) volts ("V" symbol on meter), the
battery should be recharged before load testing. If recharging does not bring voltage
to 12.4 (24.8), battery is defective. If meter needle is off scale to the left, check for
loose or reversed clamps; otherwise battery is defective.
4. Note battery's rating in Cold Cranking Amps (CCA). If the rating is not printed on
the battery, use the following guidelines to estimate battery size. Small (4 cyl) 300 CCA; Medium (6 cyl) -400 CCA; Large (8 cyl) -500 CCA.
5. Depress load switch for 10 seconds. Left RED switch for 12V batteries. Right
WHITE switch for 24V batteries.
6. Read meter at the end of 10 seconds - with switch depressed. Refer to LOAD
TEST ANALYSIS chart.
COMPENSATING FOR LOW TEMPERATURES
Low temperature has a degrading effect on batteries and will affect test results.
This can be compensated by reading a different scale.
If battery is 50°, read scale 100 CCA less then battery rating.
If battery is 30°, read scale 200 CCA less than battery rating.
If battery is 10°, read scale 300 CCA less than battery rating.

IN 15 MINUTE PERIOD. EXCEEDING DUTY CYCLE MAY CAUSE INCORRECT READING,
PROTECTION CIRCUIT TO DISENGAGE BATTERY, AND DAMAGE TO THE UNIT.

CHARGING VOLTAGE TEST
This test measures the output voltage of the alternator/regulator. Check for under or
overcharging - which leads to poor battery performance and short life.
ENGINE SHOULD BE AT NORMAL OPERATING TEMPERATURE
1. Connect tester clamps to battery as described in Steps 1-2 under Battery Load
Test.
2. Turn off all lights and accessories. Operate engine at fast idle (approximately
1500 RPM).
3. Do not operate tester's load switch.
4. Read meter voltage. Meter needle should be in Green (OK) area of Charging
System scale. (Note; 12V on left side scale - 24V right side scale).
5. Turn on high beam lights and blower on high. Meter needle should remain in
Green (OK) area.
6. If meter needle goes to the Red (LO or HI) areas, the charging system is not
operating correctly.
Trouble Shooting Hints
LO Voltage - may be caused by loose belt, defective voltage regulator or defective
alternator.
HI Voltage - may be caused by loose or corroded connections or defective voltage
regulator.
STARTER MOTOR TEST
This test identifies excessive starter current draw, which makes starting difficult and
shortens battery life. Perform Battery Load Test - proceed if battery is "Good".
ENGINE MUST BE AT NORMAL OPERATING TEMPERATURE
1. Connect tester clamps to battery as described in Steps 1-2 under Battery Load
Test.
2. Disable the ignition so the car will not start.
3. Crank the engine and note the voltage reading during cranking.
4. A meter reading of 9 volts or less for 12V systems or 18 volts or less for 24V
systems indicates excessive current draw. This may be due to bad connections
or a failing starter motor; or the battery is too small for the vehicle's requirements.
