Both rolls used,
wheels on both
rolls. Mode used
for AWD vehicles.
May also be used
for 2WD vehicles.

Channel 100 calculates total power avail-
able to move the vehicle, torque split chan-
nel is valid for AWD vehicles. For 2WD
vehicles, the torque split will be misleading,
as losses from the non-driven wheels will
be incorporated into the calculation.
2
Both rolls used,
wheels on both
rolls. Mode used
for front wheel
drive vehicles.
1
0
Channel 100 calculates power available at
the front wheels only. Although the rear
wheels are on the rear roll, any power
derived at that roll, positive or negative, is
ignored in the wheel power calculation. The
front load cell will calculate appropriate
losses from the rear rollset.
3
Both rolls used,
wheels on both
rolls. Mode used
for rear wheel
drive vehicles.
0
1
Channel 100 calculates power available at
the rear wheels only. Although the front
wheels are on the front roll, any power
derived at that roll, positive or negative, is
ignored in the wheel power calculation. The
rear load cell will calculate appropriate
losses from the front rollset.
4
Front roll used,
rear wheels off
rear roll. Mode is
used for front
wheel drive vehi-
cles.
1
0
Channel 100 calculates power available at
the front wheels only. The rear wheels are
off the rear roll. Any power derived at that
roll, positive or negative, is ignored in the
wheel power calculation. The front load cell
will calculate appropriate losses from the
rear rollset.
5
Rear roll used,
front wheels off
front roll. Mode is
used for rear
wheel drive vehi-
cles.
0
1
Channel 100 calculates power available at
the rear wheels only. The front wheels are
off the front roll. Any power derived at that
roll, positive or negative, is ignored in the
wheel power calculation. The rear load cell
will calculate appropriate losses from the
front rollset.
6
Rear roll used,
front wheels off
front roll. Front
rollset driveshaft
disconnected.
Mode is used for
extra long rear
wheel drive vehi-
cles.

off the front roll. Any power derived at that
roll, positive or negative, is ignored in the
wheel power calculation. The rear load cell
