Basic EVAP Test 

o

A flow meter ball indicating flow 

= 

flow going into (or through) the system being leak-tested. This

is normal while the system is being filled with smoke.

o

A flow meter ball indicating flow 

after 

the system is filled 

= 

a leak in the system being tested. The

higher the ball is in the flow meter, the larger the leak size.

o

No flow in flow meter 

= 

no flow through the system, or no leak.

Control Valve Leak Size Reference Points 

The tester’s control valve has calibrated leak size orifices built into 
it.  The 

.

010” (0.25 mm), 

.

020” (0.5 mm) and 

.

040” (1.0 mm) 

reference points calibrate the flow meter in order to 

quantify 

the 

leak size in the system being leak tested. 

Calibrate the Flow Meter 

1. Position the Control Valve to a leak size.  

(Figure 1)

.

2. Press START button and observe the measurement of the flow

meter's indicator ball.

3. Position the flow meter's red pointer flag so that it aligns with

the measurement observed in the previous step 

(Figure 2)

.

NOTE: This flow meter measurement indicates the EVAP Pass or Fail 
line for that leak standard. 

Testing the EVAP System 

1. Connect 

Leak

finder

® supply line to EVAP system.

2. Position Control Valve on either TEST (non-smoke) or SMOKE (full flow).

3. Press START button and fill the system until the flow meter ball stops

descending. Observe position of ball as compared to red flag.

>

Above red flag = FAIL.

>

Below red flag = PASS.

NOTE: If system failed and if previous test was performed in TEST mode 
(without smoke), then you must alleviate all pressure from EVAP system so 
that smoke can be introduced. Then set control valve to SMOKE (full flow) 
setting, introduce smoke and look for smoke and/or dye to find the leak(s). 

NOTE: The flow meter measurements for quantifying a leak are most accurate 
when the 

Leak

finder

® 

Control Valve is in TEST setting. 

NOTE: 

When testing a closed system, such as the EVAP system, it is best to 

purge the ‘non-smoke’ air out of the system by leaving an opening in the system 
being filled (e.g. EVAP vent). Close the system once smoke exits that opening 
and continue to fill with smoke.  This quickly fills the system with smoke.
