5.8.9 OPERATING MODE SELECTION AND LDAR PROCEDURES
Use this sub-menu to select between the two available operating modes:
HYGIENE
This is the standard mode that displays instantaneous concentration readings and
compares them to alarm limits and performs TWA and STEl calculations. It also enables
features such as Rolling Graph display and real-time data transfer to a PC.
SEARCH (LDAR)
This mode records individual sample readings during a window of time initiated by the
user, designed for Leak Detection and Repair (LDAR) sampling. To measure a sampling
point:
1. Select Search Mode in this menu
2. Set the User ID and the first Site ID in the following two menus. Exit to the main menu.
3. The display shows "Ready...Start Sampling? When at the desired sampling location,
press the Right key to start the pump and initiate the sampling period.
4. When the maximum or otherwise desired reading is observed, press the Down key
to record the sample concentration. If a second or more sampling point during this
sampling period, press the Down Key again, as many times as desired.
5. When satisfied with the sampling reading(s), press the Right key, and the unit asks
"Stop Sampling?" Press the Left Key to return to the same sampling period or the Right
key to end the sample.
6. The Site ID is automatically incremented by one the next time a sampling is initiated.
Up to 9999 sites can be entered, after which the first site data get overwritten.
7. If the sampling period is ended without having pressed the Down key to record a
reading, no information will be stored in the Sample Record (see Computer Interface
below) but the Site ID will still be incremented when the next sampling is started.
5.8.10 SITE ID AND USER ID
Change the Site ID and User ID for LDAR as for any other alpha-numeric input. Note that
text can be entered for ease of local site and user identification. The User ID and latest
Site ID are retained if the unit is turned off and back on. To restart the User ID sequence
at 0001, it must be reset manually in this menu.

5.9 WIRELESS

5.9.1 RADIO ON/OFF
Wireless radio communication can be enabled if the instrument has a wireless module
installed. Enable this function as with any other list selection menu.
