displayed so that the user will know how many more 10-s measurements need
to be made before a new average is displayed and logged.
If there is a power failure while the instrument is in the logging mode, logging
will resume after power is restored. A note of “Data Interruption”
will be written
to the logger prior to writing the first new data line. The instrument can
accommodate multiple data interruptions due to power failures. For example,
one can purposely switch the instrument off, move to another location and
restart logging simply by turning the instrument back on. Data sets will be
separated by the data interrupt message.
To Stop Logging Data
Hold in the Select button to obtain the
Menu
. Go to the
Dat
submenu by
clicking on
Dat
. Choose and click on the
End
function. This will end data
logging. You may now return to the
Dat
menu to transmit the data to a
computer by clicking on
Xmt
(see below). The stored data will reside in
memory (even when new measurements are being made) and can be
transmitted using the
Xmt
function as often as you like. However, all stored
data are lost once logging is started again using the
Log
function. Thus, you
should always transmit your data to a computer before restarting logging.
If you fail to
End
logging prior to transmitting the data using the
Xmt
function,
the instrument will automatically execute the
End
function for you prior to
transmitting the data.
To Average Data
Hold down the Select button to obtain the
Menu
. Select and click on
Avg
to
obtain the
Avg
menu:
Avg Menu
10s 1m 5m 1h
Use single clicks to move the cursor to
10s
,
1m
,
5m
or
1h
for averaging times
of 10 s (no averaging), 1 min, 5 min or 1 hr averaging, respectively. Then click
on the averaging time you want to use. You will be returned to the main
Menu.
To exit the Main Menu and start acquiring data, click on
again.
While in averaging mode, the current 10-s measurement is displayed
alternately with the average value at 5-s intervals, as discussed above.
Averaged data may be logged, thereby greatly extending the length of time that
the data logger can be used.
