IMPORTANT:

 PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS, WARNINGS & CAUTIONS. USE 

THE PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE AND/OR 
PERSONAL INJURY AND WILL INVALIDATE THE WARRANTY. KEEP THESE INSTRUCTIONS SAFE FOR FUTURE USE.

1.  SAFETY

 

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

 

9

   ensure that there is another person within hearing range and close enough to come to your aid, should a problem arise when working  

  near a lead-acid battery.

 

9

   Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.

 

9

   Have fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.

 

9

   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.

 

9

   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 such items to the vehicle and cause severe burns.

 

9

   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.

 

8

   DO  NOT

 smoke or allow a spark or flame in the vicinity of the battery or engine.

1.2.    

GENERAL SAFETY

 

9

   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 CONSULT A QUALIFIED VEHICLE ELECTRICIAN.

 

9

   ensure that the tester is in good condition before use. if in any doubt do not use the unit and contact a qualified vehicle electrician.

 

9

   only use recommended attachments and parts. to use unapproved items may be dangerous and will invalidate your warranty.

 

9

   Keep tools and other items away from the engine and ensure that you can see the battery and working parts of engine clearly. 

 

9

   determine the system voltage before using the tester.

 

9

   if the tester receives a sharp knock or blow the unit must be checked by a qualified service agent before using.

 

9

   if the battery terminals are corroded or dirty clean them before using the tester.

 

9

   Keep children and unauthorised persons away from the work area.

 

8

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.

 

8

  

DO NOT

 cross-connect tester to battery. ensure positive (red) clamp is to positive terminal and negative (blAcK) clamp is to negative  

  terminal. if battery symbols cannot be distinguished, remember that the negative terminal is the one directly connected to the vehicle  

 bodywork.

 

8

  

DO NOT

 use the tester outdoors, or in damp, or wet locations and 

DO NOT

 use in the vicinity of flammable liquids or gases.

 

9

   ensure there is effective ventilation to prevent a build-up of explosive gases.

 

8

  

DO NOT

 use the tester for a task for which it is not designed.

 

9

   When not in use, store the tester carefully in a safe, dry, childproof location.

2.  INTRODUCTION

Professional diagnosis of battery and alternator faults. tests battery condition with as little as 1V of residual charge. no heat, no sparks and no 

misdiagnosis. checks condition of starter – no complicated connections or interpretation required. Analyses the vehicle’s charging system at rest 

and under load to determine condition of the alternator. connect the bt2002.V2 and follow the prompts on the lcd screen for straightforward 

answers. incorporates simple voltmeter for voltage tests and additional system diagnostics. rugged construction.
