Handy Polaris – Instruction Manual
2.3.3 Oxygen Units
You can choose between mg/l and PPM
2.3.4 Auto shutdown
The meter shuts down if no buttons are pressed after 2, 5, 10, 15 or 30 minutes as set. The
factory default is 5 minutes. A long setting gives shorter expected battery life. If "Off" is chosen
the Polaris MUST be switched off using the on/off button.
2.3.5 Light intensity (display backlight)
You can choose "Low" (default value), "Medium" or "High". Frequent use of high level
backlight will reduce the battery lifetime significantly.
2.4 Information
This shows the firmware version and the serial numbers for the probe and instrument.
2.5 Status list
This menu only appears if an error condition exists. Selecting this and pressing "OK" will
display a list of error conditions. For more information and help select the desired item and
press "OK". Press "Esc" several times to return to the measurement display.
