rubber hose (respective order references VMLFIXADP5 & VMLFIXADP6) or in short configuration
without hose, (order reference VMSFIXADP5 or VMSFIXADP6).
When the fuel is supplied through an automatic fuel valve, it is usually connected to one of the
vacuum ports. By using the Tee-piece (illustrated above) & it’s short piece of hose, included with the
VacuumMate,
the
fuel valve can remain connected, so that fuel can flow while synchronising.
Another possibility is to use a vacuum hand pump to keep fuel flowing (illustrated above, the
MityVac
#4000,
available from VacuumMate distributors). The advantage in this case is that there is no
influence of the
fuel valve on the vacuum readings
.
7. HOW TO PROCEED
To start
.
Make the necessary pneumatic connections. It is best to connect the channel 1 hose first. Start the
engine and let it warm up. Connect the
VMR6WS
to a suitable battery or dc electrical input. If using
the
VMR6ME
model: move the battery selector switch lever from left to right to reset it to “ON”, as it
has an auto-switch-off feature which switches off the VacuumMate when there has been no “activity”
for 5 minutes to protect it’s rechargeable internal batteries.
