1. SAFETY INSTRUCTIONS
DANGER! BE AWARE, LEAD-ACID BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS VERY
IMPORTANT TO READ AND FOLLOW THESE INSTRUCTIONS CAREFULLY, EACH TIME YOU USE THE BATTERY TESTER.
Follow these instructions and those published by the battery and vehicle manufacturers, and the maker of any equipment you intend to use in the vicinity of
the battery. Remember to review warning marks on all products and on engines.
1.1. PERSONAL PRECAUTIONS
! Ensure there is another person within hearing range of your voice and close enough to come to your aid, should a problem
arise when working near a lead-acid battery.
! Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
! Have fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
! Wash immediately with soap and water if battery acid contacts skin or clothing. If acid enters eye, flush eye immediately with cool, clean
running water for at least 15 minutes and seek immediate medical attention.
! Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit current
which is high enough to weld a ring or the like to metal, which would cause severe burns.
! Ensure hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine, remove ties and contain long hair.
" DO NOT smoke or allow a spark or flame in the vicinity of battery or engine.
1.2. GENERAL SAFETY INSTRUCTIONS
! Familiarise yourself with the application and limitations of the tester as well as the potential hazards. Also refer to the vehicle manufacturer's hand book. IF IN ANY
DOUBT CONSULT AN ELECTRICIAN.
! Ensure the tester is in good order and condition before use. If in any doubt do not use the unit and contact an electrician.
! Only use recommended attachments and parts. To use non-recommended items may be dangerous and will invalidate your warranty.
! Keep tools and other items away from the engine and ensure you can see the battery and working parts of engine clearly.
! Confirm that the battery to be tested is 12 volt before attaching clamps to battery terminals.
! Should the unit suffer excessive shock, it must be checked by a qualified service agent before further use.
! If the battery terminals are corroded or dirty clean them with a solution of water and baking soda before attaching the clamps.
! Keep children and unauthorised persons away from the working area.
" DO NOT dis-assemble the tester for any reason. The tester must only be checked by qualified service personnel.
# WARNING! To prevent the risk of sparking, short circuit and possible explosion DO NOT drop metal tools in the battery area, or allow them to touch the battery terminals.
" DO NOT cross connect leads from tester to battery. Ensure positive (+/RED) is to positive and negative (-/BLACK) is to negative. If symbols cannot be
distinguished, remember that the negative terminal is the one directly connected to the vehicle bodywork.
" DO NOT pull the cables or clamps from the battery terminals.
" DO NOT use the tester outdoors, or in damp, or wet locations and DO NOT use within the vicinity of flammable liquids or gases.
! Ensure there is effective ventilation to prevent a build-up of explosive gases, and do not cover or obstruct tester ventilation louvres.
" DO NOT use the tester for a task for which it is not designed.
! When not in use, store the tester carefully in a safe, dry, childproof location.
2. INTRODUCTION
12Volt Battery tester with large, easy-to-read LCD digital display and battery condition LEDs. Can be set to specific battery CCA rating. Applies appropriate load across
terminals and reads voltage performance. Will also check charging voltage and starter motor circuit.

3. OPERATION
3.1 Battery Load Test (Performed in order to evaluate a battery's ability to crank
an engine).
3.1.1 Disconnect the battery from the vehicle and ensure the battery tester is off.
3.1.2 Connect the negative "-" (black) clamp to the negative battery terminal and
likewise, connect the positive "+" (red) clamp to the positive battery terminal.
Ensure a good electrical connection.
3.1.3 Set the CCA (Cold Cranking Amps) rating of the battery on the meter, by way
of the SET CCA switch (fig.1.B). The default setting for the BT91D is 500 CCA.
With each change of CCA level, a short beep will sound.
The appropriate rating should be shown on the battery, if not, consult the
supplier/manufacturer for information.
3.1.4 With the clamps connected to the battery terminal, the digital display will
indicate the battery's STATE OF CHARGE.
Should this be less than 12V, the battery will need to be recharged before
load testing can take place. If, after charging for a sufficient period of time
the battery still produces a state of charge test result of less than 12V, the
battery is defective and should be replaced immediately.
Should the display remain blank, check for loose connections and ensure the
correct polarity has been observed. If all is as it should be and yet the
display remains blank, the battery is defective and should be replaced.
3.1.5 To perform the load test, simply depress the LOAD TEST switch (fig.1.A),
a single beep should sound. The load test will last for 10 seconds after which
a continuous beeping will sound. To stop the beeping, remove one of the
testing clamps but NOT before noting the readings/results given by the meter
(see 3.1.6)
3.1.6 When the test is complete, the digital display will show the load voltage of
the battery, unless the battery's STATE OF CHARGE was below 12V in
which case the display will read "-L-" (see Section 3.1.4).
The status of the battery i.e. Good, Weak or Bad, is indicated by the LEDs
present on the meter (fig.1.C).
Note: If "ERR" is displayed, the tester itself or it's relay are defective.
