2.4 Probe cutting according to tank depth
ATTENTION: DUT-E AF/232/485/CAN allow cut off up to any required probe
length with mandatory further calibration.
DUT-E A5/A10/F/I allow cut off up to 30 % of the initial length of the measuring
probe with no further calibration.
DUT-E cutting procedure instructions:
1) Measure the depth of the tank from mounting plate to the bottom.
IMPORTANT: It is required to leave a 20 … 30 mm gap between the edge of the
measuring probe and the tank bottom to:
• provide at least 10 mm operation area for bottom spring stopper (if the bottom
spring is fixed in full loading position the bayonet mounting plate can get damaged);
• avoid the short circuit of the measuring probe tubes with conductive mud or water
at the tank bottom.
2) Cut off DUT-E probe so that the edge of the probe is in 25 mm above the bottom of the
tank.

RECOMMENDATION: Cut DUT-E probe with a metal hacksaw. Carefully clean the
edge and wash the tubes with clean fuel (see figure 14).
3) After cutting the measuring probe of DUT-E AF/232/485/CAN models, you need to carry out
the sensor calibration using Service DUT-E service software (see 3.10.3 ).
