3.2 Bump Test
Bump test is the process which checks and verifies the performance of the
monitors and ensures that sensors are correctly responding to the target gas.
To perform a Bump Test, follow the below:
✓
Insert the monitor(s) into the bay facing down.
✓
Slightly press down on the monitor until it locks into place.
✓
Press the Bump Test button for 2 seconds to execute Bump test.

the test (see Figure 3).
