OPERATION and USE :
BEFORE TEST
1. Before you test a battery in a vehicle, turn off the
ignition, all accessories and loads. Close all the
vehicle doors and the trunk lid.
2. Make sure you have put 4 AA 1.5V batteries into the
battery chamber. Oxyride batteries are NOT rec-
ommended because of the initial 1.7 Volt output.
If the internal 1.5V batteries run out of power, the
display will show “POWER LOW”. Replace those AA
1.5V batteries before starting a new test.
Note that nothing will be seen on the display until
the tester is connected to a vehicle battery.
3. Make sure the battery terminals are clean. Wire
brush them if necessary. Connect the red clamp
to the positive battery terminal post; connect the
black clamp to the negative battery terminal post.
For the most accurate results, clamp on the lead
part of the terminal only. Attaching to the clamp or
fixture rather than directly on the terminal will lead
to unstable wrong test results.
4. Paper load:
a. Open the clear cover.
b. Place a new paper roll
in the compartment.
c. Paper will be fed auto-
matically when the sen-
sor of printer is sensed.
