Tank Calibration
1. Use the knob to select a channel and press
OK
to open the channel configuration dialog.
See figure 44.
(a) Specify the sensor function (what is sensor used for), sensor type (which sensor is
used), is sensor isolated (thermocouples only, otherwise ignored), report time inter-
val (not used in this version), filter time constant (small values – sensor responds
quickly, larger values – sensor responds slowly, shows average).
(b) Digital sensors require number of pulses per event. For example, Rotax engine
require 1 pulse per engine revolution and some fuel flow sensors require up to 8000
pulses per liter.
(c) Fuel flow sensors require a fuel flow correction factor. A value larger than one,
increases the fuel consumption indication, while a value smaller than one decreases
fuel consumption indication.
(d) Press
Save
to accept new parameters. This closes the dialog and returns to the
step one.
(e) Press
Reset
to reset the channel (use this on unused channels).
(f) Press
Close
to close the channel editing without accepting new parameters.
2. Once all channels are set, you must press
Save
in order to transfer the new configuration
to Daqu. This also makes new configuration active.
3. Press
Close
to exit the dialog. This does not save the new configuration.

options are also available.

Tank Calibration
Before tank calibration can be performed, fuel level sensors must configured. Sensor config-
uration was described in section 6.13 starting on page 47.
The tank calibration icon displays a list of three options:
Setup tanks
combines sensors, hardware units and tank names. This must be done
first. After this other two options become available.
Calibrate sensors (min/max)
is used to calibrate a tank, which shape is already
known. Here, only empty tank and full tank limits are required.
