Bump Test
A bump test is used to test that the monitor is working properly. During a bump test, a known concentration of gas is
applied to the sensor to verify that the sensor responds to the gas, and the alarms activate. This is the only way to
effectively confirm that all characteristics of the monitor and the sensor are working correctly.
WARNING
A bump test should be conducted before each day’s use.
Ensure that you are in a clean environment before performing a Bump Test.
The monitor must be calibrated if it fails a Bump Test.
To perform the bump test:
•
Prepare a gas cylinder with a CO2 concentration that exceeds the low and high alarm set points.
•
Press and hold the Function key and power button for three seconds in the measurement mode. Press the Function
key until “TEST” is displayed and press the power button two (2) seconds to enter the mode.
•
Press the Function key until “BTS is displayed and press the power button to activate it.
•
After pressing the power button, apply a CO
2
gas over low and first alarm and the 30 seconds count down is
displayed.
•
Once the test has passed, “SUC” (
V
) icon appears on the display. If test is failed, “FA” (
X
) mark appears on the display.
