Date And Time
Date
Month (MM) and Day (DD) have two digits each, while the year (YYYY) uses four
digits.
Time
The QRAE 3’s time must be set using the 24-hour format, following hours, minutes, and seconds
(HH:MM:SS).
8.3.5.2.
Display
LCD Contrast
The display’s contrast can be increased or decreased from its default setting. You may not need to
ever change the default setting, but sometimes you can optimize the display to suit extreme
temperature and ambient brightness/darkness conditions.
Use the [Y/+] key to change the LCD contrast. When you are done, press [MODE] to highlight
“OK” and press [Y/+] to save your change. Otherwise, highlight “Cancel” and press [Y/+] to
abort changes and revert to the original setting.
LCD Flip
The display can be configured to flip 180° automatically when the QRAE 3 is turned upside-
down. The LCD Flip feature can be set to On or Off.
Backlight
The display’s backlight can be set to illuminate either automatically, based on ambient light
conditions, or manually, or it can be shut off.
8.3.5.3.
Pump Speed
If the QRAE 3 is equipped with a pump, the pump can operate at two speeds, high and low.
Running at low speed is quieter, extends pump lifespan, and conserves a small amount of power.
There is almost no difference in sampling accuracy.
Note:
High speed should be used for exotic
sensors and for taking samples via a hose from a long distance.
8.3.5.4.
Site ID
Choose and enter an 8-digit Site ID to uniquely identify the particular site where the instrument is
to be used. The first four digits can be an alphabet letter or number, while the last four digits can
only be numbers. This Site ID is included in the datalog report.
Note:
Advance through the alphabet and numbers (0 through 9) by one with each press of the
[Y/+] key. To scroll quickly, hold down the [Y/+] key for as long as you want it to scroll rapidly.
Save your changes by highlighting “OK” and pressing [Y/+].
8.3.5.5.
User ID
Enter an 8-digit alphanumeric User ID to uniquely identify a user. This User ID is included in the
datalog report.
