4 Measurement accuracy check
4.1 Basic principles
DUT-E accuracy check test is conducted to determine the reduced and absolute error of fuel
level measurement on the particular Vehicle.
The procedure of DUT-E accuracy check requires filling/draining of the fuel tank and comparing
sensor data with the actual amounts of filling/draining.
Fuel drain is carried with manual or mechanical pump.
Calibrated measuring containers must be used to determine the exact amount of
drained/refilled fuel.
ATTENTION: The amount of any fuel filling/draining during the accuracy test should
not be less than 20 % of total tank capacity.
