Study Notes
Password Input and Programming Mode
- Default password is 0000; enter to access Programming Mode.
- Password screen appears only during the first Programming Mode access after powering on.
- Once entered, the password does not need re-entry until the device is turned off/on again.
- Calibration menu is highlighted upon entering Programming Mode, allowing navigation with [N/-] and [Y/+].
Menu Structure in Programming Mode
- Main menus include Calibration, Measurement, Alarms, Datalog, Wireless, and Monitor.
- Submenus allow for specific settings like Fresh Air calibration, Gas settings, Datalog intervals, and Alarm Limit adjustments.
Calibration Process
- Calibration can split into steps if different gases are required for sensors.
- Bump test involves connecting a calibration gas source and verifying gas concentration before initiating the calibration.
- A countdown screen accompanies the calibration process. It can be aborted at any time.
- Calibration results indicate pass/fail status for each sensor.
Bump Test for Individual Sensors
- Individual sensor tests are initiated through menu navigation.
- Calibration value should match that of the calibration gas source before proceeding.
- A pass or fail indicator appears at the end of the test.
Data Logging Features
- Datalogging records gas concentration, time, Site ID, and User ID data.
- The memory allows retention of six months of data for five sensors with one-minute intervals.
- Options for data clearance when necessary, noting that erased data cannot be recovered.
Datalog Options
- Users can adjust datalog intervals from 1 to 3600 seconds, defaulting to 60 seconds.
- Data Selection permits choice of types stored in the datalog: Minimum, Average, Maximum, Real-Time.
- Datalogging has three initiation methods: Auto, Manual, Snapshot.
Wireless Settings
- Devices can join networks through a designated PAN ID.
- Users can set wireless transmission intervals to 10, 30, 60, 120, or 240 seconds.
- Off Network Alarm can be enabled to alert when disconnection occurs.
Factory Reset and Calibration Settings
- Factory reset restores all wireless settings to factory defaults.
- Important to note that settings lost in a reset cannot be retrieved.
- Default calibration settings for MultiRAE PID sensors include various range specifications and calibration points.
LCD Contrast Adjustment
- LCD contrast can be modified for optimal display under varying conditions using [Y/+] and [N/-].
- Default settings may require adjustments based on environmental factors.
Important Calibration Gas Settings
- MultiRAE Pro: 0 to 2000 ppm, 10 ppb resolution, 100 ppm span with Isobutylene as calibration gas.
- MultiRAE: 0 to 5000 ppm, 100 ppm reference, calibrated to Isobutylene.
- MultiRAE Lite PID: 0 to 1000ppm, 1 ppm resolution, uses Isobutylene for calibration.
Software Integration
- Requires connection to a PC for advanced calibration via ProRAE Studio II.
- Initial setup involves entering a password and detecting the instrument through appropriate communication modes.
