4. Acoustic signal
An acoustic signal can be switched on in the following three cases:
1. Key is pressed
2. Alarm/warning message appears
3. Measurement is stable and has endpointed (stability signal appears)
5. Expert/Routine modes
The meter has two working modes:
●
Expert mode: the factory default setting enables all functions of the meter.
●
Routine mode: some of the menu settings are blocked.
The concept of the two working modes is a GLP feature that ensures that important settings and
stored data cannot be deleted cannot be unintentionally changed under routine working conditions.
The meter only allows the following functions in the routine mode:
●
Calibrating and measuring
●
Editing user, sample and sensor IDs
●
Editing the MTC temperature
●
Editing data transfer settings
●
Editing system-settings (PIN-protected)
●
Storing, viewing and printing data
●
Running the instrument self-test
6. Screen settings
Screen contrast
The screen contrast can be set from levels 1 to 6.
Auto-shutoff
The meter will auto-shutoff when no key is pressed in a preset time to save the battery life. The time
can be set (5 min, 10 min, 30 min, 1hour, 2 hour) for the meter auto-shutoff or set to "Nev e r" to
disable this feature. If "never" is selected, the Auto-off override icon appears on the dis p lay and
you need to manually switch off the meter by pressing ON/OFF.
