2.
Enter the Bump Test menu. It is accessible either through Programming Menu/Calibration or
using the following easy shortcut:
With the instrument running in Normal Mode and the main measurement screen shown,
press both [Y/+] and [N/-] at the same time and hold them for 5 seconds. If all the sensors
have warmed up, the Multi-Bump Test menu then appears:
Otherwise, the menu appears after the warm-up is complete (while it is warming up, the
screen indicates that you must wait for the sensors to warm up).
Note:
If you do not apply gas within a couple of minutes, the screen changes briefly to
indicate gas has not been applied, and then the instrument returns to its normal reading
screen.
3.
Install the calibration adapter on the MultiRAE and connect it to the calibration gas. Turn on the
gas to initiate flow.
4.
Press [Y/+] to start the bump test. While the bump test is being performed, the readings for each
sensor are shown. Once the bump test completes, pass/fail test results and readings are shown for
each sensor.
Note:
If a PID or other sensors are installed in the instrument require a dedicated cylinder of gas
to calibrate, the instrument will prompt for calibrating such sensors at this point.
5.
If a PID or other sensors installed in the instrument require a dedicated gas cylinder to calibrate,
the instrument will prompt to calibrate such sensors at this point. Disconnect the gas cylinder and
connect the next (for example, 100 ppm Isobutylene for a PID).
6.
Press “OK” to proceed to the PID sensor test. Turn on the gas and press Start ([Y/+] button).
While the bump test is being performed, PID sensor readings are shown. Once the bump test
completes, pass/fail test results and readings are shown for the PID sensor.
Note:
If other installed sensors require a dedicated cylinder of gas to calibrate, the instrument
prompts for calibrating these sensors at this point.
