Flowtrecs Mini is equipped with multi-functional screen which displays metering
data chosen by the user. Data in the upper screen is changed by simultaneously
pressing both buttons for a short time. Switching data works in a loop so
by subsequent presses we can access other readings such as: Time, motohours,
RPM, and again Time, etc.
3. LCD SCREEN DESCRIPTION
Data on side screens are changed by short presses of particular buttons and it works
in a loop too. So by subsequently pressing the left button we will see on the left screen: km/l, l, l/h.
Similarly by pressing the the right button such data as: km/h, V, OFF will be displayed

4.TACHOMETER
The tachometer function is active when the icon RPM is visible on the top screen. If it's not visible
we must simultaneously press both buttons a few times until it's displayed. The measurement engine's
RPM speed is carried out by the analysing the rate of tacho pulses from shifter (for outboard engines)
or from ignition circuits ( for inboard engines). These pulses should be conducted to
the green wire coming out of the bundle. In na case of carbureted engines it's necessary to use
limiter because of their excessive amplitude (delivered as separate part).
Attention: In case of direct connection of the green wire to pulses in carbureted
engine the input circuit of pulse measurement will be permanently damaged.
For injection engines the green measuring wire can be directly connected to the shifter. If tacho pulses
are not available in shifter, an additional sensor of RPM should be used in the form of hallotron placed
near the flywheel. After correct connection of the measuring green wire and choosing the function
of RPM measurement we start the engine, leave it in idle and observe the readings on the top screen.
If they are in the range of 600-700 RPM it indicates that the parameter settings of tachometer are
correct and can be regarded as finished. If readings are different e.g. 1300-1400 RPM it means
the necessity to change the multiplier of tachometer reading. To do that we must press and hold both
buttons simultaneously for a few seconds until the RPM reading is blinking and until the reading from
P2 to P12 etc. is seen in the bottom left corner of the screen. It is the multiplier by which
the number of tacho pulses are multiplied indicating the actual RPM value. This multiplier is to be
changed with buttons ( left down and right up ) in such a way that the RPM speed displayed on the top
screen matches the actual engine speed. At this moment it's necessary to press again both buttons
simultaneously (this time shortly) to write new settings and resume normal operation.
