BATTERY TESTER

The batteries will gradually age over time after being made. As the
battery electrode plate surface age and produces sulfides, the batteries
can not undergo the chemical reactions effectively, this is the main
reason the most batteries cannot continue to be used. At this time, the
internal resistance of the batteries increases. The older batteries, the
greater the internal resistance. By accurately measuring the value of
internal resistance, you can determine the aged of the batteries.
Currently, conductance method is the most advanced method to
measure the internal resistance of the batteries.
It has a proven result of electric conductance test and 1/2 CCA
discharging measurement test can be identical. Given result fully
shows the accuracy of this tester. During operation, avoiding large
current to discharge the battery can protect the battery from possible
damages and heat generation. This allow the machine operator
perform tests several times within a short time period. In recent years,
the conductance method to measure the internal resistance of a battery
is being widely used around the world.
PRECAUTIONS
●Read the user manual carefully and use correctly.
●The tester is designed to test 12/24 volt automotive batteries. It can
not be used for other batteries.
●A freshly charged battery will show a higher voltage than normal; if
this is the case, switch on the headlights for 30 seconds to allow the
voltage to stabilize.
●Always connect directly to the leads of the battery terminals;
connection to a remote post or vehicle ground will affect test result.
●Always connect single battery.
●Connect the tester to the battery, red clip to the positive electrode
and black clip to the negative electrode. The analyzer will start
automatically and show the voltage of the battery. If the analyzer do not
turn on, check whether the clip connect the wrong electrode.

Maintenance
●To get access to paper roll, lift
the prying plate in the middle of
the paper cover up from tester.
●Replace the thermal paper.
●Pull out the head of paper and
put it under the black rubber
roller and close the paper cover
back.
Install the print paper as shown
in the diagram, draw out print
paper through the scroll bellow,
and put the paper under the
roller. If there is a print blank,
please check whether the print
paper is installed correctly.

BSR(British S tandards). Continuous output on average current
intensity at 0°F(-18°C), the minimum voltage can be maintained over
6.0 volts for 150 seconds.
DIN(German Institute for Standardization). For 100DIN, each 100DIN
battery at 0°F(-18°C), the battery needs to carry 100 amperes, and
over 8.0 volts for 150 seconds.
IEC(International Electrotechnical Commission). Continuous output
on average current intensity at 0°F(-18°C), the minimum voltage can be
maintained over 8.4 volts for 60 seconds.
JIS(Japanese Industrial Standards). Calculate with amperes / hour, 20
hour rate.
AH(Ampere Hour)(20 hour rate). Each 100AH battery at 80°F(27°C),
the battery needs to carry 5 amperes, the minimum voltage can be
maintained over 10.5 volts for 20 hours.
RC(Reserve Capacity)(IEC). Is the time (minute) each battery at
80°F(27°C), the average power load reach 25 amperes per minute and
the minimum voltage can be maintained over 10.5 volts. For a RC
110MIN battery, the battery can provide the vehicle continued to drive
110 minutes in case of failure of the vehicle generator.
CCA(Cold Cranking Ampere)(I EC). Every full battery after high
intensity discharge for 30 seconds, the minimum voltage can be
maintained over 7.2 volts.
For a 500CCA battery, the battery needs to carry 500 amperes for 30
seconds, the minimum voltage can be maintained over 7.2 volts.
CA(Cranking Ampere). The significance is similar with CC A, the
difference between CCA and CA is the testing temperature, CA is the
result at 0 degrees Celsius. The value of CCA will be lower than CA,
because the low temperatures result in poor performance of the
battery.
