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 that there is another person within hearing range and close enough to come to your aid, should a problem
3
arise when working near a lead-acid battery.
Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
3
Have fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3
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
3
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
3
to weld such items to the vehicle, and cause severe burns.
Ensure that hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine. Remove ties and contain long hair.
3
DO NOT smoke or allow a spark or flame in the vicinity of the battery or engine.

1.2
GENERAL SAFETY INSTRUCTIONS
Familiarise yourself with the application, limitations and potential hazards of the tester. Also refer to the vehicle manufacturer’s hand book. IF IN ANY DOUBT
3
CONSULT A QUALIFIED ELECTRICIAN.
Ensure that the tester is in good condition before use. If in any doubt do not use the unit and contact a qualified electrician.
3
Only use recommended attachments and parts. To use unapproved items may be dangerous and will invalidate your warranty.
3
Keep tools and other items away from the engine and ensure that you can see the battery and working parts of engine clearly.
3
Confirm that the battery to be tested is 6 or 12 volt, and not 24 volt, before using the tester.
3
If the tester receives a sharp knock or blow the unit must be checked by a qualified service agent before using.
3
If the battery terminals are corroded or dirty clean them before using the tester.
3
Keep children and unauthorised persons away from the work area.
3
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
p
battery terminals.
DO NOT cross-connect BT91/2 tester to battery. Ensure positive (RED) lead is to positive terminal and negative probe is to negative terminal. If battery
7
symbols cannot be distinguished, remember that the negative terminal is the one directly connected to the vehicle bodywork.
DO NOT use the tester outdoors, or in damp, or wet locations and DO NOT use within the vicinity of flammable liquids or gases.
7
Ensure there is effective ventilation to prevent a build-up of explosive gases.
3
DO NOT use the tester for a task for which it is not designed.
7
When not in use, store the tester carefully in a safe, dry, childproof location.
3
DO NOT load test for more than 5 seconds at a time. Use for longer may result in the tester overheating and will invalidate your warranty.

INTRODUCTION
The BT91/1.V2 tests 6 and 12V lead-acid batteries under load.
The BT91/2 tests 6 and 12V lead-acid batteries under load and can also be used as a normal volt meter to check the condition of starting and charging systems.
3.
OPERATION
WARNING! Ensure that you read, understand and apply the safety and operational instructions before apply the tester probes to the battery. Only when
p
you are sure that you understand the procedures is it safe to proceed with the testing process.
WARNING! During and after load testing the load resister (see fig. 1.B) will be very hot. Do not touch or place on vulnerable surfaces.
p
Note:
ON THE FIRST LOAD TEST SMOKE MAY BE EMITTED FROM THE COIL ON THE TESTER. THIS IS OIL
BURNING OFF AND IS NORMAL.
3.1
PREPARATION
WARNING! Ensure that the vehicle, or battery, is in a well ventilated area before starting to test.
p
3.1.1
Check battery casing for cracks or leakage and confirm that it is 6 or 12 volts.
3.1.2
Clean battery terminals.
3.1.3
If possible, check electrolyte levels and top-up with distilled water as necessary.
3.1.4
Unless otherwise specified tests are carried out with all electrical items switched off.
3.2
BT91/1.V2
3.2.1
Press one probe to the positive (+) battery terminal and the other probe to negative (-) terminal. Note that
this tester is not polarity sensitive. If the pointer does not move, either there is a bad connection or the
battery is completely dead.
3.2.2
Note the meter reading - compare the meter reading with load test chart (3.5) to determine battery condition.
DO NOT test for more than 5 seconds.
Note:
For 12 volt batteries there are two meter scales - the upper for batteries with capacity greater than 40Ah and
the lower for those with capacity less than 40Ah.
3.3
BT91/2 SEE FIG 1
3.3.1
For all the following tests, connect the tester to the battery as follows:
3.3.2
Press the positive (+) lead probe onto the positive battery terminal and negative probe (-) onto the negative terminal.
If the pointer does not move either there is a bad connection or the battery is completely dead.
3.3.3
Ensure that the cable is clear of hot or moving engine parts, particularly if a starter or charging test is to be carried out.
3.4
NO-LOAD BATTERY VOLTAGE
3.4.1
Unscrew the knurled knob (fig 1.A) to isolate the load resistor (fig 1.B) and then connect the tester to the battery as described above (engine switched
off).
