The following is a step by step example
showing how easy it is to programme a
BA364D clock.
Step 1 Enter the programming mode
Put the BA364D in the programming
mode by simultaneously pressing
P
and E. Assuming a security code has
not already been entered the
instrument will respond by displaying
‘Function’ which is the first parameter
in the main menu. See Fig 5.3
Step 2 Select the instrument function
With ‘FunctIon’ displayed, press P to
reveal the existing instrument
function. If this is not ‘CLOC’, select
‘CLOC’ using the
Up or Down button.
To prevent accidental changes the
new setting will only be executed after
the pass word ‘SurE’ has been
entered.
Press P which will produce a display
of ‘Set nO’ with the ‘nO’ flashing.
Using the
uP or Down button change
‘nO’ to ‘YES’ and press P again which
will result in a display of ‘0000’. Using
the
Up or Down button to adjust each
digit and the P push-button to transfer
control to the next digit, enter the
pass word SurE. Note: S is entered
as 5.
Finally, press E which will execute the
function change and return the
instrument to the ‘FunctIon’ prompt in
the main menu.
Step 3 Select the display format
Using the Up or Down button scroll
through the main menu until
‘dISPLAY’ is found; press
P to reveal
the existing setting. Using the Up or
Down buttons select ’24:00’, which
will provide a 24 hour format without
seconds. Finally return to the main
menu by pressing
E .
Step 4 Setting the reset time
Using the Up or Down button scroll
through the main menu until ‘rSEt t’ is
displayed; press
P to reveal the
existing setting with one digit flashing.
Using the
Up or Down button to adjust
the flashing digit and the P button to
transfer control to the next digit, enter
12:00 the required reset time. Finally
pressing
E will return the instrument
to the ‘rSEt t’ prompt in the main
menu.
Step 5 Define the security code
The security code prevents
unauthorised access to the
programme functions. Select 'COdE'
from the main menu and press
P
which will reveal the existing security
code. Using the
Up and Down
buttons enter the new code 1112 digit
by digit. The
P button will transfer
control between digits. When the new
code has been entered, press
E to
return to the main programme menu.
Step 6 Setting the displayed time
Using the Up or Down button scroll
through the main menu until ‘SEt’ is
displayed. Pressing
P will reveal the
clock display with one digit flashing.
The current time can be entered by
adjusting the flashing digit using the
Up or Down button and the P button
to transfer control to the next digit.
When set as required, pressing
E
twice will start the clock and return the
instrument to the display mode.
