Set-up Mode
All system parameters can be changed and a basic calibration initiated from this
mode. To prevent any unauthorised changes, the user must enter a four
number security code before the mode can be accessed.
! After this mode has been selected, the instrument will suspend
its operation. If no key is pressed within 5 seconds after
selection of this mode, the instrument will revert to the normal
operating mode.
Press the MODE key until the number 5 is displayed in the top left-hand corner.
After the security code has been correctly entered, there are 8 sub-modes of
operation, (see Figure ), from which the set-up parameters may be changed;
these are :
• Set Averages
