Note:

Hose connections must be completely airtight,
otherwise measurements will not be correct.
Ensure that measuring hose is not pinched at
hood or side window.
Pressing memory key M on turbocharger tester
will store the last measured value until memory
key M is pressed again or tester is switched off.
The decimal point in the display flashes to
indicate that the value is being stored.
If the battery voltage of the turbocharger tester
drops below the minimum level, an arrow will
appear at the top left of the display.
Before checking, drive vehicle quickly for at
least 3 km (choose a safe route that does not
include stopping).
A second mechanic is required to note readings
with the vehicle moving.
