The display of the drift values for the sensitivity calibration depends on the setting of the calibration method If total calibration is selected here only the selected measuring range for the sensitivity calibration is displayed For single calibration all measuring ranges can be individually adjusted and can therefore have different drift values which are shown separately The drift values can reset to 0 0 with the Reset drift values instruction When you reboot the device all measuring ranges have 0 0 as the drift value OXYMAT 61 Operating Instructions 12 2011 A5E00123067 02 Operation 5 4 5 4 1 OXYMAT 61 5 4 Measuring ranges Measuring ranges After selecting the measuring range functions in the main menu the following screen appears when the third softkey Measuring ranges is pressed Meas ranges 40 Range selection 41 Define meas ranges Figure 5 21 Measuring ranges submenu The measuring ranges menu contains all functions you need for selecting and setting the measuring ranges This menu is protected by the code of code level 1 Select measuring ranges function 40 40 Select range 0 0 0 0 0 0 0 0 Autorange Figure 5 22 Select measuring ranges You can select a fixed measuring range or switch to automatic measuring range switching All selection options are subject to mutual interlocking Automatic measuring range switching is only possible under the following conditions
