Screen 3 displays the Counter readings "Engine Operation Time" accumulated as the
total time of engine operation in all modes including idle run.
Screens 4...6 display the Counters readings of "Engine Operation Time in "Idle",
"Optimal" and in "Overload" Modes" accumulated by DFM as a total engine operation
time in corresponding modes.
Screen 7 displays the Counters readings of "Engine Operation Time in "Tampering"
Mode" accumulated by DFM as a total time of engine operation when consumption
was higher than maximum possible. Value increase of this counter indicates the
incorrect installation of the fuel flow meter or possible fuel theft.
Screen 8 displays the Counter readings of "Engine Operation Time. Clearable", which
was accumulated as a total time of engine operation in all modes, including idling.
Counter data could be reset using service software or by applying a magnetic key
(3...5) s to a switching zone of DFM's cap when Screen 8 is active.
Screen 9 displays the Counter readings of "Total Fuel Consumption. Clearable", which
was accumulated by DFM since its production. Counter data could be reset using ser-
vice software or by applying a magnetic key (3...5) s to a switching zone of the DFM's
cap when Screen 9 is active.
Screen 10 displays the Counter readings of "Total Fuel Consumption. "Tampering"
Mode" accumulated by the DFM, measured as the amount of fuel higher than maxi-
mum consumption. Value increase of this counter indicates the incorrect installation of
the fuel flow meter or possible fuel theft.
Screen 11 displays the Counter's "Interference Time" accumulated by the DFM as the
total time of exposure to external factors (strong magnetic field). Increase of the values
of this counter may indicate an installation of the fuel flow meter near a source of
strong electromagnetic radiation or deliberate attempts to lock the fuel meter.
Screen 12 " Instant Fuel Consumption" displays current value of fuel consumption. It
can serve for a visual check of device operability and its correct installation.
Screen 13 displays "Total Differential Fuel Consumption" counter value, accumulated
in differential mode.
Screen 14 "Instant Differential Fuel Consumption" displays current differential fuel
consumption (a difference between fuel consumption in chamber of each flow meter)
on display of DFM installed in fuel feed line and operating in pair with DFM installed in
fuel reverse line.
Note — If Slave Flow meter is disconnected, current differential fuel consumption
will not be displayed. Master Flow meter's display will show screen similar to
"Tampering" mode screen.
Screen 15 "Battery Charge in Percentage of the Maximum" displays the value of
remaining charge of integrated battery.
Note — When the environment temperature is below 10 °C, displayed value of
remaining charge can decrease by (10...30) %.
Screen 16 "Temperature in the Measuring Chamber" displays current temperature
value in the measuring chamber of the fuel flow meter.
Screen 17 "Firmware Version" displays the firmware version (X.X) installed on the fuel
meter.
