Bump Test

WARNING! 

Perform a Bump Test before each day’s use to verify proper device operation.

Failure to perform this test can result in serious personal injury or death.

 

This test quickly confirms that the gas sensors are functioning. Perform a full calibration periodically to ensure accuracy and immediately if the device fails the Bump Test. The Bump Test can be performed using the procedure below or automatically using the GALAXY Test Stand.

Equipment

See accessory section for ordering information for these components.

•

Calibration Check Gas Cylinder

•

0.25 liters/min. Flow Regulator

•

1/8” ID Superthane Ester Tubing

•

ALTAIR 4X Calibration Cap

Performing a Bump Test

1. From the normal measure screen press the q-- button to display “BUMP TEST?”. 2. Verify the gas concentrations displayed match the Calibration Check Gas Cylinder. If they do not, adjust the values through the Calibration Setup menu as described in Device Setup.
3. Attach the calibration cap to the device. a. Insert tab on calibration cap into slot on device. b.   Press calibration cap as shown until it seats onto device. c.   Press both side tabs down onto device until they snap in. d.   Ensure that the calibration cap is properly seated. e.   Connect one end of the tubing to the calibration cap. f.   Connect other end of tubing to the cylinder regulator (supplied in the calibration kit).
4. Press the  button to start the bump test then open the valve on the regulator. The hourglass will flash and the sensors will respond to the gas. 5. Close the valve after bump testing. After the Bump Test completes, the device momentarily displays “BUMP PASS” or “BUMP ERROR” along with the label of any sensor that failed before returning to Measure mode. If the device fails the Bump Test, perform a calibration as described in Calibration .

The Ö symbol will be displayed in the Measure mode for 24 hours after a successful Bump Test.
