INSTRUCTION MANUAL
WARNING:
Before using the equipment, read carefully all instructions.
1. GENERAL SAFETY FOR OPERATING THIS EQUIPMENT
- During charging, the batteries emit explosive gasses: avoid
generating flames and sparks. DO NOT SMOKE.
- Before carrying out the test, position the batteries in a
ventilated place.
- In order to prevent damage to the vehicles' electronics,
carefully read, store safely and scrupulously observe the
instructions provided by the manufacturers of the vehicles
themselves; the same applies to indications supplied by the
batteries manufacturer.
- Keep away from the reach of children.
- Protect the eyes. Always wear protective goggles when
working on lead-acid batteries.
- Avoid contact with battery acid. Should anyone be sprayed
by or come into contact with the acid, wash immediately
the part involved with clean water. Continue to rinse until a
doctor will attend to the person affected.
- It is important to connect the cables to the correct polarities.
Connect the red clamp (+) to the battery's positive terminal,
the black clamp (-) to the negative (earth).
- Use this equipment in well ventilated areas.
- Prevent black and red clamps coming into contact when
they are connected to the battery, since this can cause the
melting of the batter or other metal objects.
- Wear appropriate clothing. Do not wear flapping garments
or jewellery that might get caught into moving parts. While
working, the use of electrically insulated protective clothing
is recommended as well as anti-slip footwear. Should long
hair be worn, wear a cap to contain them.
- Do not use on batteries that are damaged or have a cracked
or broken case.
- Never remove the connecting clamps from the battery
during testing.
- While testing, and immediately after, do not obstruct or
touch the cooling vents.
- When positioning the tester inside the engine of a vehicle,
make sure the tester casing does not come into contact
with the battery terminals or with uncovered electrical
connections, which can create short-circuits.
- Do not connect the tester to the battery while the engine is
running.
- Do not expose the product to rain.
GB
- Keep this manual for the warnings, safety precautions and
user procedures it contains.
2. INTRODUCTION AND GENERAL DESCRIPTION
Tester for 12 V battery (Fig. A). Equipped with analog instruments
and sound signal that warns when the charge test is finished.
This device checks the charge state and starting capacity of the
12 V batteries used in vehicles. It also checks the ignition system
(alternator).
3. OPERATION AND USE
BEFORE CARRYING OUT THE TEST
- Make sure the battery terminals are clean.
- Before testing a vehicle battery, remove the ignition key, switch
off the lights, remove all the connected accessories, close the
doors and the boot.
NO-LOAD VOLTAGE LEVEL CHECK
- Rotate the central knob of the tester to the left until it locks
completely. (OFF position).
- Connect the red clip (+) to the positive pole of the battery and
then the black clip (-) to the negative pole.
- Read the value on the voltmeter, referring to the "STATE OF
CHG" line; if the reading is lower than 12.4 Volts, recharge the
battery.
- If the recharge does not take the voltage to at least 12.4 Volts,
the battery is faulty.
STARTING CAPACITY
(CCA = Cold Cranking Amps, which is the cold starting current).
The CCA value is given in Amperes by the manufacturer usually on
the battery itself: for example 520 A (EN).
This test evaluates the capacity of the battery to start an engine, the
tester obtains current from the battery while it measures its voltage level.
The voltage level of a good battery remains relatively stable under
charge, while a faulty battery loses voltage quickly.
HUMIDITY - If the tester has not been used recently, the humidity
that can condense between the carbon disks evaporates during
the first or second test. (Be careful not to mistake this emission of
steam with the emission of smoke caused by overload).
- Rotate the central knob of the tester to the left until it locks
completely. (OFF position).
- Connect the red clip (+) to the positive pole of the battery and
then the black clip (-) to the negative pole.
- Rotate the knob to the right in order to position the needle of
the "DC AMPS" in correspondence with the value given in Ah by
the battery (green scale, "AMP HOUR"). If the battery Ah value
is not known, the same test can be carried out setting the CCA
value (declared by the manufacturer which is usually printed on
the battery itself and is expressed in Amperes: for example 520
A (EN), referring to the blue scale (BATTERY COLD CRANK
RATING).
- As soon as one of the 2 values has been set, the instrument
simulates a battery charge that can be read on the black scale
(Amps).
- This current value is maintained for 15 seconds, after which the
buzzer gives a sound signal.
- Read the voltage on the "DC VOLTS" instrument, and the
position of the needle on the "BATTERY TEST" scale. In
addition, rotate the central knob to "OFF" quickly to zero the
tester.
- If the battery is good the needle should be positioned in the
green "OK" area.
- If the battery cannot maintain the charge, the needle will be in
the red "replace" area.
- Warning: the product supplies power during the test, so
wait at least 15 minutes before carrying out another test.
RECHARGE SYSTEM TEST
This test measures the output voltage of the alternator and
checks for the presence of under or overload that determine bad
performance and a shorter battery life.
- Rotate the central knob to the left until it locks completely. (OFF).
- Connect the red clip (+) to the positive pole of the battery and
then the black clip (-) to the negative pole.
- Switch on the engine, taking it to approx. 1500 rpm.
- Disconnect the vehicle electric charges: for example switch
