PASSWORD PROTECTION
Setting the GLP parameters (calibration alarm time-out, instrument
ID code, time and date) can be password protected. If password is set
to a value different from 0000 (factory setting), the user will be asked
to enter the password.
• Select the desired GLP parameter code.
• Enter the password using the arrow keys.
• Press the ALT and CFM keys
to confirm.
• If password is incorrect, the meter will return to the function
selection mode without any warning message.
• If password is correct, the meter provides access to the GLP
parameters.
PARAMETER SETTING
• Once the parameter code has been entered, the appropriate
message will scroll across the LCD for a few seconds.
• The current value of the selected parameter on the upper LCD
and the parameter code on the lower LCD will be displayed. The
first digit will blink if the parameter can assume continuous
values. All the digits will blink if the parameter can assume only
a fixed set of values.
• Enter the new value using the Arrow keys.
• Press ALT and CFM to confirm the value.
