measured so far for inclusion in the next average to be displayed and logged. If 1-min
averaging is used, this number will increment from 0 to 29; for 5-min averaging, the
number will increment from 0 to 149; and for 1-hr averaging, it will increment from 0 to
1799. This number is displayed so that the user will know how many more 2-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.
Note that entering the menu will interrupt the averaging interval that is in progress,
and the averaging interval will start over when the menu is exited and measuring is
resumed.

To Stop Logging Data
Hold in the Select switch to obtain the
Main
Menu
. Go to the
Admin Menu
and then
the
Dat
submenu. Choose and click on the
End
function. This will end data logging.
You may now return to the
Dat
submenu to transmit the data to a computer by clicking
on
Xmt
(see Section 3.14 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 Set the Time and Date
From the
Main Menu
, select the
Admin
menu and the
Cfg
submenu. Next, select the
D/T
submenu. The display will read, for example:
D/T:
14:32:21
17/10/2016
meaning that it is 21 seconds after 2:32 p.m. on October 17, 2016 (military time and
European date). To change a number in the date and time, rotate the Select switch to
underline the numeral you want to change. A single click then causes a blinking
cursor to cover that numeral. The number can then be changed by rotating the Select
switch. Once the number is correct, click on the Select switch to turn off the blinking
cursor. You may now rotate the Select switch to choose another numeral to change.
Once the time and date is correct, clicking on
will set the internal clock to that time
and return the display to the
Cfg
menu. As in setting a digital watch, the seconds
should be set in advance of the real time since the clock starts to run again only when
