Function
All sensors tested and calibrated tick mark (all sensors have been bump tested and
calibrated; no sensor is overdue for a bump test or calibration according to the
intervals configured on the instrument
3.1.2. LCD Flip
The QRAE 3 senses its vertical/horizontal orientation, and can automatically flip the display180
degrees, making it easy to read if the QRAE 3 is upside down. (You can turn this feature on or off
in Programming Mode, under “Monitor.”) As the QRAE 3 is tilted, the sensor detects its
orientation and inverts the screen when it passes its horizontal position.
3.1.3. Keys & Interface
The QRAE 3 has two keys:
MODE
Y/+
In addition to their labeled functions, the keys labeled [MODE] and [Y/+] act as “soft keys” that
control different parameters and make different selections within the instrument’s menus. From
menu to menu, each key controls a different parameter or makes a different selection.
Two panes along the bottom of the display are “mapped” to the keys. These change as menus
change, but at all times the left pane corresponds to the [MODE] key, and the right pane
corresponds to the [Y/+] key. Here are examples that show the relationships of the keys and
functions:
In addition to the functions described above, either key can be used to manually activate display
backlighting. Press a key when the backlighting is off to turn it on.
