You’ve bought your first Delphi evap tester. Now what?
Firstly unpack everything and plug in your evap unit and charge it for a day. Make sure the charger is 12 VDC 1 amp (1000ma), while it’s charging, check that you have 3 adapters; black, blue, & red, with the necessary washers in this order; foam, spacer, lastly the thin sealing washer. You’ll need to buy extra thin sealing washers… You should also have 2 x 16” approved clamping pliers. Next, attach the larger diameter hose with the quick disconnect, it will be 3’ or 10’. DO NOT overtighten, just nip it… hose CANNOT be over 10’ long. Next, attach your large regulator to your refillable bottle of nitrogen… put your thumb over the end and turn it on… set the gauge to 80 PSI.. remove thumb and try again… Now, attach the small regulator with curly hose… put your thumb over the end of the hose and turn the bottle on… set the small regulator to 32 PSI.. repeat a couple of times… attach the small hose to your evap unit… do NOT overtighten, just nip it… turn on the bottle and check for leaks, you can spray with Windex or a similar product. NOTE; when turning on your nitrogen bottle, DO IT SLOWLY, otherwise you could blow a hose off inside the unit.

Calibrate your Delphi evap tester
Once the evap unit is charged, turn it and the bottle regulator on… wait 10 mins for the gases to settle… push 5 & continue, the screen will show about 32 PSI… if needed adjust the small regulator slightly so the screen reads 32 PSI… push continue… push 3 & continue, this will start a calibration… follow the prompts… ONLY connect the hose to the calibration tank when told to do so… set the valve to the middle position OFF… start the calibration by pushing continue… do NOT rush the calibration… when u turn the valve count to 5 before pressing continue… when the first stage is done the screen will read tank volume of about 2.0… if it doesn’t read about 2.0, note the reading & check your regulators… turn the machine off then back on and start the calibration again. Follow the prompts for the LOW stage, the screen will read around 0.020… next is the high stage, the screen will read around 0.040… if all is good, push continue to complete the calibration, if not, turn the machine off and repeat the calibration after checking regulator pressures… AFTER 10 FAILED CALIBRATIONS, YOUR UNIT WILL LOCK YOU OUT… always call us after 2 failed calibrations.

Setup your Delphi evap tester for your shop
Evaps are now Plug & Play…. When using with your ESP/OPUS BAR97 smog machine you no longer have to contact OPUS / ESP…. connect the serial wire and select “station manager functions” click on it. now select “evap tester record purge” and click on it… the machine will say “purge successful” if everything is working fine. if not it will say “purge failed”… it may take a couple of tries… During this process your station number will be installed in to your Delphi…
When using with your Worldwide BAR97 smog machine you no longer have to contact OPUS / ESP…. connect the serial wire and select “station manager menu” click on it. now select “LPFET test settings” and click on it… now select purge LPFET test records… follow prompts… it may take a couple of tries… Once your Delphi is working correctly… call Worldwide and ask them to put your station number in to your Delphi…

My Delphi will not calibrate
Check to see if your regulators are maintaining the correct PSI, 80psi & 32 psi… Press 5 & Continue, note the PSI Return in 5 mins & check that the PSI is still the same. It should not climb In 5 more mins, check the PSI, it should still be the same. If the pressure climbs, a new small regulator will be needed. Delphi evaps DO NOT usually climb, they maintain the exact PSI.
