Bump Testing
A bump test can be performed on an individual sensor (Single Sensor Bump) or a group of sensors (Multi
Sensor Bump) combined into Multi Cal. Select. The same gas is used for a bump test as for calibration.
Typically, two cylinders of calibration gas are needed to perform a bump test or calibration on an
instrument with a PID sensor and electrochemical and LEL sensors. This may require one gas cylinder
with Isobutylene or another VOC test gas to test the PID sensor, and another with a 4-gas mix to test
electrochemical (such as CO, H
intelligently splits the process into two consecutive steps: first, the wizard prompts for testing
electrochemical and LEL sensors, and then it tests the PID sensor.
For a manual bump test, a constant-flow regulator producing 0.75 to 1 liters per minute should be used.
Attach one end of a "T" using Teflon tubing to the filter on the PGM-65XX inlet. (You can use RAE Systems
P/N: W01-3003-000).
Teflon tubing must be used to test or calibrate the PID sensor. Follow the steps described here to perform
a manual bump test:
1. Turn on your PGM-65XX by pressing and holding [MODE] (the middle button) and allow the
instrument to boot up fully until the main measurement screen with sensor names and readings is
shown.
Make sure all of the instrument's sensors have warmed up before performing the bump test. The
instrument will take the time to warm up the sensors prior to enabling access to bump test menus.
You can tell a sensor has warmed up if you see a reading next to it name on the display. If it has not
warmed up, you see three dashes ("---") next to it.
2. Enter the Bump Test menu. It is accessible either through Programming Menu.
3. Connect the PGM-65XX 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, 10 ppm Isobutylene for a 4R+ ppb PID and the next gas should be
100 ppm; 100 ppm for 7R+ PID, and the next gas 1000 ppm).
