& off. [Y/+] Answer “Yes” to a question; increase a number; test alarm; alarm condition acknowledgment The Q-RAE Plus monitor has two operation modes: 1. Basic mode is the simplest mode of operation. The monitor alternately displays the instantaneous concentration readings and the sensor names after the monitor is turned on. - Page 9 OPERATION 2. Advanced mode, shown schematically in Figure 4, displays more information than the Basic mode and allows access to more programming functions. The Programming Mode is explained in detail in Chapter 4 of the long form manual. Sensor Names / Instantaneous Readings Yes &...

2.4. Datalogging This function applies only to datalogging monitors. The Q-RAE Plus multi-gas monitor calculates and stores the gas readings based on a user-specified datalogging period and the type of measurement. Both average and peak values can be stored for each sensor during each datalogging interval. -

PROGRAMMING & CALIBRATION to Table 5 and then apply a source of mixed standard reference gases*. The display will count down from 60 to 0 seconds, and then show the name of each sensor, the message “cal’ed!” and the calibrated value for each gas. The readings should be very close to the span gas values. -
