After choosing the desired value, a single click turns off the blinking cursor and allows
you to scroll to the other parameter or to
to exit the submenu.
Once the values of
Z
and
S
are set, clicking on
will return the display to the
Cfg
menu, and another click
on
will return to the
Main Menu
. The calibration parameters reside in non-volatile
memory and are not affected by power failures.
3.15. To Set the Time and Date
From the
Main Menu
, select 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
the set time is entered; in this case by clicking on
.
3.16. To Change the Output Baud Rate
From the
Cfg
submenu, select
I/O
to give the input/output menu, for example:
I/O Menu
Bdr Ext LCD
Selecting
Bdr
and clicking allows you to change the baud rate used for data
transmission. The choices are 2400, 4800, and 19200 bps. The submenu appears
as:
2400 4800 19200
After clicking on a chosen baud rate, use
to return to the
I/O
menu.
3.17. To Turn the Analog Inputs On and Off and Change the Analog Output
Scaling Factor
Choosing
Ext
from the
Cfg
/
I/O Menu
allows you to turn the analog inputs on and off
and to set the scaling factor for analog outputs:
Ext Menu
V_IN V_OUT
The two submenus allow one to turn the analog inputs on and off (
V_IN
) and to
change the scaling factor for the analog voltage output (
V_OUT
).
