No smoke generation can occur when Testifire XTR2 is not used for several days, and for the majority of cases, a manual purge will resolve the issue and return the tester to full working order.
Alternatively, Inspect the Smoke Generator
1. Turn the unit off. Remove the battery, smoke cartridge and smoke generator.
2.
Hold the smoke generator so you are looking into the cartridge opening at the silver tube. Press the flexible tube at the lower back of the generator and see if the liquid comes out of the silver tube.
Keep doing this until it does.
3. Carefully re-insert the smoke generator, then the smoke cartridge and finally the battery. Ensure the clips engage securely for each component, and especially for the generator. Press and hold the generator down firmly for a few seconds to "seat" the generator. When inserting the smoke cartridge, retain the pressure on the back of the cartridge for at least 3 seconds to ensure a secure fit. Switch the unit on.
4.Ā
Tap the settings icon from the bottom left-hand corner of the LCD display, then tap the āPurgeā option.
Tap the Purge icon to begin a manual purge cycle. This will take approximately 60 seconds to complete, and smoke should be produced in this time.
