UT673A/UT675A Battery Tester
Overview
UT673A/UT675A battery tester, with its leading-edge conductivity test technology,
accurately and rapidly helps users to measure the cold cranking amps capability of the
vehicle starting battery, healthy state of the battery itself, detect the common fault of
vehicle starting and charging system, which helps repair vehicle quickly.
Safety information
Please carefully read this manual and follow the warning and safety information before
use.
To avoid fire and overcurrent, please read all rated values and symbol descriptions
before use.
Do not open the case cover. Do not turn on the tester if its cover or front panel is open.
Do not touch the connectors and components if the tester is powered on.
Please contact the authorized repair personnel to detect, repair, maintain the tester
if you find any fault on it.
Do not use in humid, explosive or inflammable environment.
Keep the tester surface clean and dry. Keep it well-ventilated.

Operation instruction
1. Connect the red and black clips of tester to the measured battery, red is positive,
black is negative, the tester screen will display startup interface. If the battery voltage
is lower than 7.0V, the test will become abnormal.

Remark
12V battery, the capacity is 60Ah,
the cold-start current is 500A.
The standard value is 300A.
12V battery, the capacity is 60Ah,
the standard value is 250A.
12V battery, the capacity is 60Ah,
check JIS CODE conversion table
and find that 26A19R corresponds
to 220A for CCA.
12V battery, the capacity is 60Ah,
check JIS CODE conversion table
and find that 26A19R corresponds
to 220A for MF CCA.
If the standard is not found,
estimate CCA value according to
the battery capacity.
