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 2.2 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 '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
counter 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 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. 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 terminal block(s) by gently pulling.
Remove the five screws securing the rear panel
and lift off the panel to reveal the link – see Fig 10.
