PASSWORD PROTECTION
Setting of the GLP parameters (calibration alarm time-out, instru-
ment 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 by the arrow keys.
• Press the ALT and CFM keys to
confirm.
• If password is wrong the meter will return to the function selection
mode without any warning message.
• If password is correct, the meter provides access to the parameter.
PARAMETER SETTINGS
• 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.
