3.13 GLP Functions
A variety of GLP functions are available via the GLP Setup menu.
A reminder that calibration is due can be set via the Cal Reminder option. Once this option is set a
valid calibration is required to use the 3520 after the time limit has elapsed. This option is
DISABLED by default.
The interval time is set in hours on this menu.
NOTE:
A calibration should be performed immediately after the setting of this value to
reset the clock. This should be done as soon as set up is complete.
The on screen reminder can be accompanied by an audible alarm. This is set using the audible
alarm setting on this menu.
NOTE:
The use of the Calibration Reminder feature will prevent the user from
performing measurements with the 3520 until a valid calibration is carried out.
The user and batch ID can be used to identify sets of samples and a specific user. This information
is printed when data is output to the printer. The batch number is also stored in the results memory.
3.13.1 Security
To control access to set up options and data manipulation functions a security code can be set
using this menu. When enabled a password is required to make any changes to the set up menus.
When the code is ENABLED a user can measure a sample, log data and calibrate the unit, but
cannot change settings within the set up screens until a valid password is entered.
