2.4 Data Logging
Logging Data – Non Survey Mode
The “START/STOP/RST/SAVE” key is used for manually logging data and for reading a barcode. When
this key is pressed, the instrument then displays the message “SPACE AVAILABLE XX” for one second,
while the current reading is being logged. The display will also show the message “SPACE AVAILABLE
###” between each data point that is logged. This is to inform the user of the amount of remaining data
memory. When the memory is full (i.e. no further memory remains open for data storage), the instrument
will display “LOG BUFFER FULL.” Also, an icon will appear at the bottom of the screen. At that point, the
user has two options: a) upload the data to a PC in order to release the memory for any additional data
logging, or b) overwrite existing data memory by pressing the “START/STOP/RST/SAVE” key. In this
situation the instrument will prompt the user with the “OVERWRITE YES NO?” message to confirm the
operation. If the user presses the “SEL” key, the operation will start without uploading data to the PC. If
the user selects “NO,” the data will remain available for uploading.
Logging Data – Survey Mode
The “SURVEY MODE” allows for data logging at pre-determined, pre-loaded, locations. When this feature
is selected from the main menu, the list of available sequences will be displayed. The desired sequence is
then selectable through the usage of the “UP,” “DOWN,” and “SEL” keys, respectively. After a particular
sequence has been selected, the location of the first measurement to be taken will be displayed at the
bottom of the screen. Pressing the “START/STOP/RST/SAVE” key will save the current reading at that
location. The display will then indicate the location of the next reading to be taken. (Note: if the device is
equipped with a barcode scanner, it will be necessary to position the front of the unit directly over the
barcode, prior to pressing this key, in order to obtain a valid scan.)
Individual survey locations may be skipped by pressing the “UP” or “DOWN” arrow keys before logging
data (i.e. before pressing the “START/STOP/RST/SAVE” key). This will cause the next location in the
sequence to be displayed in the lower left portion of the screen. When all of the locations in the survey
have been logged (i.e. have data saved in reference to them), then the message “SURVEY COMPLETE”
will be displayed for approximately five seconds.
The log-data function may be disabled by selecting “NONE” from the “LOG DATA SUB-MENU.”
The unit has the capability of storing, and then selecting from, a maximum of 10 separate and distinct
survey sequences. Each sequence may contain up to 50 separate locations.
Data Review
All previously stored data may be reviewed at anytime through the unit’s LCD display. This can be
accomplished by highlighting “DATA REVIEW” from the “MAIN MENU,” then pressing the “SEL” key. The
“DATA REVIEW SUB-MENU” will now be displayed (see Figure. 2-29). Highlight one of the selections,
and then press “SEL.” If specific survey sequence data is to be viewed, highlight that sequence; then
press “SEL.” The survey sequence “SESSION SUB-MENU” will then be displayed (see Figure 2-30).
Highlight one of the sessions; then press “SEL.” Measured data, along with time/date stamp and barcode
(if applicable), will be displayed on the LCD. The readings will be listed from the earliest (oldest) readings
to the latest (newest). The UP and DOWN arrow keys can be used to scroll through large numbers of
stored data points, if needed (see Figure 2-31).
Data logged from each individual session can be deleted/erased by first highlighting the desired session
(Figure 2-30), then pressing “START/STOP/RST/SAVE.” At the prompt, highlight “YES” using the UP or
DOWN arrow keys; then press “START/STOP/RST/SAVE” (Figure 2-32).
