5. Set the rotary switch to 200 kΩ.
6. Connect the red test lead to the secondary outlet and the black
test leads to the primary - pole as fig 5.
The secondary outlet is generally in range 6 kΩ to 30 kΩ. Refer to
various kind of automotives manuals.
Battery condition test
Test if battery is fully charged.
1. Set the rotary switch to 20 VDC position.
2. Insert the red test lead into the V terminal and the black test lead
into the COM terminal.
3. Turn off the ignition switch.
4. Turn on the driving lights for 10 sec. to release charges from the

The testing result are shown in contrast as follows. 12,6V-100%.
12,45V-75%. 12,3V-50%. 12,15V-25%.
Battery consumption test when the engine is off
The test is useful for determination of the additional consumption of
the battery.
1. Turn off ignition key and make sure lights etc are closed.
