BESA-12P User’s manual 1.0 - Introduction 1.1- BESA-12P (Battery Electrical System Analyser) This Analyser uses the modern technology in battery testing which can test batteries as they are without charging before test. Testing procedures are quick and easy with repeatable results. Test Results can be printed directly on its attached printer or it can be stored in the computer for records.
BESA-12P User’s manual Its result is consistent and repeatable and can be performed numerous times without heating up the unit. It is very safe as it does not create any sparks when connected to the battery terminals during testing on the vehicle.
BESA-12P User’s manual 2.0 Safety Measures: For safety reasons, read this manual thoroughly before operating the Tool. Always refer to and follow the safety instructions and testing procedures provided by the car or equipment manufacturer. The safety messages presented below and throughout this user‟s manual are reminders to the operator to exercise extreme care when using this test instrument.
BESA-12P User’s manual Engine parts become very hot when engine is running. To prevent severe burns, avoid contact with hot engine parts. Do not wear loose clothing or jewelry while working on engine. Loose clothing can get caught in fan, pulleys, belts, etc.
BESA-12P User’s manual During testing on the battery whist it is still in the car, make sure the engine is OFF. Do not store the analyser near high humidity or temperature area. Exposing to extreme temperatures will cause damage to the unit.
