2.5.12 Direction of count: ‘uP or dn’
This parameter defines whether input pulses
increment or decrement the display. i.e. whether
Input A of the BA368C is an up-counter or a down-
counter.
To check or change the count direction select 'uP
or dn' from the menu and press
P which will reveal
the present setting. 'uP' indicates that the
instrument is an up-counter and 'dn' that it is a
down-counter. Pressing the
Up or Down buttons
will toggle the display between the two settings.
When set as required, press the
E button to enter
the setting and return to the main menu.
2.5.13 Reset value: ‘rSEt UAL’
This function defines the value to which the display
is reset when the local or remote reset is operated.
This allows the BA368C to be used as a pre-set
down counter.
When the instrument is programmed as an up-
counter, ‘rSET UAL’ is normally set to zero.
To check or change the reset value select 'rSEt
UAL' from the main menu and press
P which will
reveal the current setting. The value of the
flashing digit may be changed by pressing the
Up
or Down buttons. When this digit is correct
pressing P will transfer control to the next digit.
When the reset value is set as required, press the
E button to enter the revised number and return to
the main programme menu.
2.5.14 Local reset of total display: ‘LOC- rSEt’
This function allows the local reset of the total
display to be turned on or off. When turned on,
operating the
Up and Down push-buttons
simultaneously for more than two seconds in the
display mode will reset the total display to the reset
value ‘rSEt.UAL’. See 2.5.13
To check the status of the local reset function
select 'LOC-rSEt' from the menu and press
P
which will reveal if the function is 'On' or 'OFF'. If
required press the
Up or Down button to change
the setting, followed by the E button to return to the
main menu.
The total display may also be reset to zero
remotely by connecting terminals 7 and 8 together.
See Figs 2.1 and 2.2
2.5.15 Resetting grand total: ‘CLr. Gtot’
The grand total is a separate eight digit counter
which duplicates the total display, but is not
cleared when the total display is reset.
The grand total may be viewed when the
instrument is in the display mode by operating the
E and Down push-buttons simultaneously.
The grand total can only be reset to zero from the
'CLr. Gtot' function in the main programme menu.
To zero the grand total select 'CLr. Gtot' and press
P which will cause the instrument to display 'Clr.
no' with 'no' flashing. Continuously press the Up
or Down push-buttons until 'CLr. YES' is displayed
and then press P which will result in a 'CLr. 0000'
prompt with one digit flashing. Using the Up , and
Down buttons and the P button to move to the next
digit, confirm the request by entering the password
'SurE'. Note 'S' is entered as '5'. Pressing
E will
then reset the grand total counter to zero and
return the instrument to the 'CLr. Gtot' prompt in
the main menu.
WARNING
After resetting the grand total to
zero the old grand total can not be
recovered.
2.5.16 Security code: ‘CodE’
The calibration and conditioning of the BA368C
may be protected by a four digit security code
which must be entered before access to the
programme menu is allowed. New instruments
are programmed with the default security code
0000 that allows unrestricted access to all
programming functions without entering a security
code.
To enter a new security code select 'COdE' from
the menu and press
P which will cause the
instrument to display the current security code.
Each digit of the code can be changed using the
Up and Down push-buttons, and the P button to
move to the next digit. When the required code
has been entered press
E to return to the main
menu. The revised security code will be activated
when the instrument is returned to the display
mode.
If the security code is lost, access to the
programmable functions can be obtained by
moving the internal security link to the override
position as shown in section 1.6.1. The original
security code can then be viewed by selecting
'COdE' from the main menu and pressing
P .
