Working in the routine mode

The SevenGo pro meter has two working modes:
Expert mode The default setting enables all functions of the meter
Routine mode All system and calibration settings are fixed according to what was defined in the
expert mode.
In the routine mode the meter only allows the following functions:
- Calibrating and measuring
- Editing the MTC temperature
- Storing, viewing and printing data
Activation of the routine mode
To change to the routine mode, switch off the meter. Press Read, Mode and the right softkey simultaneously.
The meter now allows you to select the working mode.
Select "1. Routine" and confirm by pressing Select. The meter switches itself off automatically. Switch on
the meter by pressing On/Off. From now on you can work safely without the risk of unintentionally changing
settings or deleting data.
Activation of expert mode
To enable all functions, switch off the meter and press Read, Mode and the right softkey simultaneously.
Select "2. Expert" and confirm by pressing Select. The meter switches itself off automatically.
Switch on the meter by pressing On/Off. You now have access to all menu functions again.
Note
The concept of the two working modes is a GLP feature that ensures that important settings or stored data
cannot be unintentionally changed under routine working conditions.
