3.5.6 Set Time: ‘SEt t’
Set time is the setpoint which the timer counts to
or from, depending upon whether it has been
programmed as an up or down timer.
To enter a set time select 'SEt t' from the main

flashing digit can be changed by pressing the

When entering set time, seconds are always

3.5.7 Access set time setpoint: ‘AcSEt t’
This function activates a separate menu that
provides direct access to the timer setpoint (‘SEt-
t’) when the instrument is in the display mode i.e.
when displaying elapsed time. An operator may
therefore adjust the timer setpoint without having
access to the programme menus. An optional
security code may be used to prevent accidental
adjustment.
This direct access menu is enabled and the
separate security code defined from the 'AcSEt t'
function in the main programme menu as shown
in Fig 3.3
To activate this sub-menu select 'AcSEt t' from
the programme menu and press
P.
This will
display the enable prompt 'EnbL'. Pressing
P
again will reveal if the direct access menu is 'On'
or 'OFF'. The
Up
or
Down
buttons will toggle the
display between the two conditions.
If 'OFF' is selected, the operator will not have
access to the setpoint from the display mode.
Return to the 'AcSEt t' prompt in the main menu
by pressing
E
twice.
If 'On' is selected, the operator will have direct
access to the set time setpoint from the display
mode via a separate optional security code. To
define this four digit numeric code press
E
to
return to the 'EnbL' prompt followed by the
Up
or
Down
button to select the access code prompt
'AcCd'. Pressing
P
will then reveal the current
security code with one digit flashing. The code
may be changed by operating the
Up
or
Down
push-buttons and pressing the
P
button to
transfer control to the next digit. Finally press
E
twice to enter the new security code and return to
the 'AcSEt t' prompt in the programme menu.
Entering code 0000 will disable the security code
allowing direct access to the setpoint from the
display mode by pressing the
P
and
Up
buttons
simultaneously.
New instruments are supplied with this security
code set to 0000.
3.5.8 Direction of count: ‘uP or dn’
The BA364D timer will time up from zero to the
set time setpoint (‘SEt t’), or down from the set
time setpoint to zero.
To check or change the timing 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-timer and 'dn' that it is a
down-timer. Pressing the
Up
or
Down
buttons
will toggle the display between the two setting.
When set as required, press the
E
button to enter
the setting and return to the main menu.
3.5.9 Lower display: ‘dISPLAY.2’
This function turns the lower display which shows
the set time on or off. When turned off, the
BA364D will display just the elapsed time when
counting up, or the remaining time when counting
down. When the lower display is turned on, the
instrument will show elapsed or remaining time
and the set time SEt t simultaneously.
To check the status of the lower display select
'dISPLAY.2' from the menu and press
P
which
will reveal if the function is 'On' or 'OFF'. The
setting can be changed by pressing the
Up
or
Down
button followed by the
E
