4 Configuration
In the Config submenu a wide range of features such as energy saving, time and display language
settings can be selected. All features in this menu relate to the operation of the meter itself, options
and settings related to the measurements can be found in the Options menu (Page 27).
4.1 Power save
The Sentron SI meter has two options to save power and extend battery operation time: Display-off
and Meter-off. Set either one, or both, of the options to maximize use of the battery capacity:
Display-off: switch off the display after a user definable inactive time.
When the display-off option is activated, the screen will switch off after the selected time has expired
since the last key has been pressed. Pressing any key will turn the screen back on.
While the screen is turned off, the meter will still fully function and perform such actions as logging
and measuring the signals from the connected probe. Pressing a key during the display-off mode will
not evoke any action other than reactivating the display.
To set or change the Display-off setting:
Go to the Config menu,
and choose Power save.
Now select Display-off.
Toggle the on/off button and select the
display-off time between 1 and 60
minutes.
Confirm and apply with the Set button, or exit
with the Back button to discard any changes.
Meter-off: switch off the meter after a user definable inactive time.
With the meter-off function activated, the meter will power down entirely after the selected time has
expired since the last key action. The meter has to be turned back on in the same way as a “normal”
power-up; by pressing the ON button on the keypad.
When the meter is switched off using this function, the meter is entirely powered down. This means
the ISFET pH sensor circuit will be powered down as well. Since a new calibration is recommended
after a startup, it is therefore recommended to perform a new calibration after an automatic Meter-
off as well.
The meter will not power-down when the AC-adapter is connected.
