Block Testing a Multi-gas Pump Cartridge
Pump block tests.
Pump block tests are performed when you activate any pumped operating mode (leak check, pre-entry, or pump run) on your device. For more information on selecting your device's operating mode, see Gas Detection Modes.
When you are in a pumped mode, you can perform a manual block test at any time by blocking G8's inlet. This causes G8 to go into low-urgency status, and your screen prompts you that the pump is blocked. Unplug the inlet. If the device returns to OK status, your device is safe to use.
Note: When performing an automatic pump block test, G8 is in safe mode and gas alerts are not triggered. This prevents triggering false alerts from residual gas in the hose.
