OPERATING INSTRUCTIONS
1.
Visually inspect batteries for obvious damage. Do not test a battery if post are loose, case is cracked or fluid level is below the top of the plates.
With "maintenance free" batteries, see manufacturer's instructions for checking water level. Do not test a frozen battery.
2.
Be sure Voltmeter and Ammeter pointers are zeroed. Zero meters by adjusting screw on face of meter until meter points to zero.
3.
See connection precautions before connecting or disconnecting clamp prior to test.
4.
Depress FAN switch to "Automatic" and the fan will automatically turn on as the LOAD CONTROL on top of tester is turned clockwise, and
automatically go to off as the LOAD CONTROL is turned counter-clockwise.
5.
Connect RED clamp to POSITIVE (POS, +, P) battery post and BLACK clamp to NEGATIVE (NEG, -, N) battery post.
NOTE:
Depress FAN switch to "Manual" and the fan will run for as long as the tester is connected to a battery.
DISCONNECT FROM BATTERY WHILE FAN IS RUNNING, OR SWITCH IS IN "MANUAL" POSITION. To safely remove clamps
depress the FAN switch to "Automatic" and turn LOAD CONTROL KNOB counter-clockwise as far as possible. Fan will automatically be
OFF and then the clamps may safely be removed from battery.
DETERMINE STATE OF CHARGE OF BATTERY
6.
a)
Adjust LOAD CONTROL knob clockwise (CW) to 100 amps for 3 seconds. Adjust LOAD CONTROL knob counter-clockwise until the meter reads
zero. Observe the Open Circuit Voltage (OCV) on the Voltmeter.
b)
Results:
1.
If the OCV is 12.4V or higher (6.2V for 6V, 28.8V for 24V) then proceed to load test.
2.
If the OCV is between 12.4V and 11.9V the load test can be done but results maybe inconclusive. If the load voltage is above the minimum
voltage in the chart then the battery is good. If below then charge battery and retest.
3.
If OCV is below 11.9V then charge the battery before testing.
LOAD TEST
7.
a)
Figure the value of one-half of Cold Cranking Amps (CCA) rating of battery to be tested.
b)
Adjust "LOAD CONTROL" knob to the one-half of the battery's cold cranking amperage (CCA) rating using AMPERES LOAD meter as a reference.
Hold this reading. During this 15 seconds interval the amperage will probably change due to resistance changes in the cables, carbons and the
battery. Readjust the LOAD CONTROL during this 15 seconds interval to maintain the amp figure required. At the end of 15 seconds and with
the load on, read the battery's voltage on the volt scale. TURN THE LOAD CONTROL KNOB COUNTER-CLOCKWISE AS FAR AS POSSIBLE.
(OFF)
c)
The voltage reading obtained from a battery changes in relation to the temperature of the battery and also in relation to the amperage being drawn
from the battery. The "Battery Temperature Compensation" given here and on the face of the tester gives the minimum voltage that should be
obtained for the test procedure given. i.e.: The outside temperature is 60 degrees F. From chart note that the minimum volts for a good battery is
9.5 at 60 degrees F. When at the end of the 15 second test you find that the battery's voltage is equal to or greater than 9.5, the battery is good.
When the voltage is 9.4 or less the battery is defective.
When smoke is emitted from any cell of the battery, the battery is defective regardless of the test indications

STRESS TEST:
8.
a)
To determine if a battery is adequate for an application, a stress test may be applied to a battery. Determine the maximum current draw, minimum
acceptable voltage, and maximum cranking time of the vehicle in which the battery is to be installed.
b)
Run a load test at the determined current and time and check that the battery voltage is above the minimum required.

APPLICATION DATA:

ALTERNATOR TEST:
Be sure that the battery in the car, test is good. Start engine with tester connected to the battery. The charging voltage of the
alternator should be between 13.8V and 14.8V. Note on newer models this voltage may hold at a lower value until a load is applied. Apply a load
matching ½ the alternator rating the battery voltage should remain above 13.0V.
