Study Notes

Wireless Control and Submenus

Wireless features are available only if the MultiRAE has a wireless module.
In Advanced User Mode, users can turn the radio on/off; activation takes a few seconds while deactivation is instant.
Basic User Mode does not allow radio controls; settings can only be modified in Programming Mode.
The Wireless screen displays communication status and settings information such as Unit ID, Pan ID, and Channel, which are read-only for troubleshooting.

Battery Options

MultiRAE offers three battery types:
- Standard rechargeable Li-ion battery (50% runtime less than extended version).
- Extended rechargeable Li-ion battery (offers 50% more runtime).
- Alkaline battery pack (requires four AA-sized batteries).
Standard and extended batteries charge within the device when placed in its cradle or Travel Charger.

Entering Programming Mode

To enter Programming Mode, a 4-digit password (default: 0000) must be entered after powering on in Basic Mode.
If the correct password is provided, re-entry into Programming Mode doesn't require password input until the device is powered off and back on.

Programming Menus

Menus in Programming Mode include: Calibration, Measurement, Alarms, Datalog, Wireless, and Monitor.
Each menu has submenus for specific settings and adjustments (e.g., adjusting alarm limits, changing gas settings).
Access menus and changes by pressing [Y/+] to enter or edit, and [N/-] to cycle through options.

Wireless Settings Management

Users can configure the MultiRAE to join networks with a specified PAN ID without channel specification.
Wireless transmission intervals can be set to 10, 30, 60, 120, or 240 seconds; default is 30 seconds.
The Off Network Alarm function can be enabled to notify users of lost connections.

Factory Reset

Performing a factory reset will restore all wireless settings to original defaults, with no option for recovery afterwards.

Monitor and Sensor Calibration

LCD contrast can be adjusted to enhance visibility under different environmental conditions.
Bump testing requires specific setup such as a flow regulator and a calibration cap installed on the instrument.
Calibration gas specifications are outlined for various MultiRAE PID sensors, including typical calibration ranges and target gases (e.g., Isobutylene).

3-Point Calibration

To enable 3-point calibration, connect MultiRAE to a PC via Desktop Cradle or AutoRAE 2 and start the ProRAE Studio II software.
A password is necessary for software access, followed by instrument detection to initiate calibration settings.
