6.14 Resetting grand total: ‘CLr. Gtot’
The grand total is a separate sixteen digit
counter which duplicates the total display but is
not zeroed when the total display is reset to
zero. The grand total may be viewed in the
display mode in two eight digit sections as
described in section 2.1 of this manual.
The grand total counter can only be reset to
zero from the 'CLr. Gtot' function in the main
programme menu. To zero the grand total
counter 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 '0000' prompt. 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.
6.15 Security code: ‘CodE’
The calibration and conditioning of the
instrument may be protected by a four digit
security code which must be entered before
access to the programme menu is granted.
New instruments are programmed with the
default security code 0000 which 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 indicator is
returned to the operating 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. The original security code can then
be viewed by selecting 'CodE' from the main
menu and pressing
P
.
To gain access to the security code link,
remove the instrument control cover by
undoing the two ‘C’ screws – see Fig 5. If the
instrument is fitted with external push-buttons
the connecting ribbon cable should be
unplugged from the outer row of the five pin
connector. The security code override link is
located on the inner row of the five pin
connector as shown in Fig 10.
