Evaporative System Test & Diagnosis:
Phase-one:
1. Position the Selector Valve on the LeakMaster NE240 control panel to
'METER'.
2. Determine if the vehicle you are testing is governed by a .040 or .020
acceptable leak requirement Standard. Insert the LeakMaster NE240 air
supply hose (transparent hose) nozzle tip into the appropriate Standard on
the LeakMaster NE240 control panel.
3. Turn on the LeakMaster NE240 by depressing the remote starter button and
observe the position of the flowmeter's indicator ball.
4. Position the flowmeter's red 'pointer flag' so that it aligns with the
measurement observed in step 3 above (See figure 1). Release the remote
starter button and remove the air supply hose nozzle tip from the standard.
Note: This flowmeter measurement indicates the vehicle's
Pass or Fail line for that particular leak Standard.
5. Locate the vehicle EVAP Service Port and remove the green cap. (Figure 2)
6. Install the EVAP Service Port Adapter that is provided with the LeakMaster
NE240. (Figure 3)
7. Insert the LeakMaster NE240 transparent Air Supply Line nozzle tip into the EVAP Service Port
Adapter. (Figure 4)
