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. 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.
4. Install the calibration adapter on the MultiRAE and connect it to the calibration gas.
Turn on the gas to initiate flow.
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.
