Calibration and Testing
Manual Alarms Test
Under Normal Operation Mode and non-alarm conditions, the buzzer (audible alarm), visible
alarms, and backlight can all be tested anytime by pressing [Y/+] twice. If any alarm does not
respond, check the alarm settings in the Programming Menu to make sure all alarms are
enabled (selected setting under Programming/Alarms/Alarm Settings should be "All Enabled").
If any alarms are enabled but not functional, the instrument should not be used.
Bump Testing and Calibration
RAE Systems recommends that a bump test be conducted prior to each day's use. The purpose
of a bump test is to ensure that the instrument's sensors respond to gas and all the alarms are
enabled and functional.
The AreaRAE Plus/Pro multi-gas detector must be calibrated if it does not pass a bump
l
test when a new sensor is installed, after sensor maintenance has been performed, or at
least once every 180 days, depending on use and sensor exposure to poisons and
contaminants.
Calibration and bump test intervals and procedures may vary due to national legislation
l
and company policy.
During a bump test, the instrument makes a pass/fail decision based on sensor performance,
but the user still has the responsibility to make sure all the alarms are enabled and functional.
Bump (Functional) 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
sensors. As with calibration, the instrument 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.
Make sure all of the instrument's sensors have warmed up before performing a 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 its name on the display.
If it has not warmed up, three dashes ("---") are shown next to it.
Teflon tubing must be used to test or calibrate the PID sensor. Follow the steps described here
to perform a manual bump test:
