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.
- A bump test should be conducted before each day’s use.
- Ensure that you are in a clean environment before performing a Bump Test.
To perform a Bump Test:
-
On the Measuring screen, make sure oxygen reads 20.9 and the other sensors read zero.
-
Clip the calibration cap to the unit. The cap attaches to the recesses in either side of the unit. You should hear a click when the cap is secure. Note: Be sure you have the cap right-side up.
-
Ensure that the regulator is firmly attached to the gas bottle and that the hose is securely attached to the regulator and to the calibration cap.
-
From the Main screen, press the [Function] key to advance to the Calibration screen. The calibration icon and the Calibration gas settings are displayed. Typical readings clockwise from the upper-left are 50,18.0,25, and 100.
Note: Pressing the key too quickly may not advance the display. -
Press and hold the [Function] key for three seconds to enter the Calibration menu. CAL ZERO displays
-
Press the [Function] key twice to advance to the Bump Test screen. Bump test displays.
-
Press and hold the [Function] key to begin the bump test. GAS NO and a 45-second countdown timer are displayed.
-
Turn on the gas regulator. A new 45-second countdown timer appears in the lower-right corner while the rest of the display alternates between GAS IN and real-time gas measurements.
-
Watch the display as the timer counts down. Results should appear within roughly 20 seconds. If the test is successful, OK appears in each corner of the display.
-
Turn off the gas regulator, disconnect the calibration cap, and wait for the gas to dissipate.
-
Clear peaks before proceeding. See Clear Peaks in the Menu Screens section for instructions.
The monitor must be calibrated if it fails a Bump Test.
Calibration
Please see the PM400 User’s Manual for complete calibration instructions.
Fresh Air Calibration adjusts the zero offset of the toxic and LEL sensors and
sets the oxygen sensor to 20.9% Vol. Span Calibration adjusts the sensors
response to gas to account for sensor drift. It is recommended to perform a
Fresh Air Calibration prior to a Span Calibration.
