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/+].

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.
