If the “SURVEY” mode is to be selected the user must download the sequence information from a PC,
including the location of each successive measurement point, before starting to log data. Failure to do this
will cause the message “NO SURVEY DEFINED” to be displayed. If the user then presses the “SEL” key,
the “SURVEY SUB-MENU” screen (see Figure 2-20) will be displayed. The “UP,” “DOWN,” and “SEL”
keys can be used to choose the desired sequence. A prompt will then appear with the words “SHOW
LOCATION LIST?” followed by “YES” and “NO” (see Figure 2-21). If the user selects “YES” then the
complete list, for the survey sequence previously selected, will be displayed (see Figure 2-22). If “NO” is
selected then the normal operating screen will appear, along with the title of the first survey location in the
lower left corner of the LCD. A survey location may be skipped simply by pressing the “UP” or “DOWN”
arrow keys; each successive key press will display the next location in that sequence. When a sequence
in complete, a message will appear indicating that all locations have been surveyed.
If the instrument is equipped with a barcode scanner, the “MANUAL W/ BARCODE” and “SURVEY W/
BARCODE” options will be available. To use one of these features, the user must scan the barcode at the
desired location before logging any data. This is accomplished by pressing the
“START/STOP/RST/SAVE” key while simultaneously aligning the front of the unit with the barcode itself.
If the barcode scan was unsuccessful, then the message “SCAN FAILS” will appear in the lower left hand
portion of the screen (for approximately a three second period). At this point, another scan may then be
attempted. If successful, the message “PRESS S/S: LOG DATA” will appear and remain until the
“START/STOP/RST/SAVE” key is pressed. Pressing this key will then save the data that was displayed
on the screen at that point in time.
Whenever a scan takes place in the “SURVEY W/BARCODE” mode, a comparison is made between the
barcode scanned and an internal value that is stored for that particular location. If the two values do not
match, then the message “BARCODE MISMATCH” will appear for a period of three seconds.
For timed data logging, the user must set the time interval manually via the keypad. If “TIMED” is
selected the display will appear as in Figure 2- 23. The user can then set the time interval by using the
“UP”, “DOWN” and “SEL” keys. The time interval range may be set from 5 to 255 seconds. After the
“SEL” key is pressed, the time interval data is saved. (Adjustment of other settings for timed data logging
is accomplished in a similar manner.)
