Description
'A high signal at zero oxygen' may be observed during zero calibration. The following instructions show how to further localize and possibly solve this technical problem.
Abbreviation: R0
Reference: Zero calibration, OroboPOS-Connector
High zero current

- Example: First, the OroboPOS-Connector and the POS were disassembled and disconnected from the main unit. Second, the OroboPOS-Connector was connected to the O2k-Main unit without the OroboPOS. Third, the OroboPOS was connected to the OroboPOS-Connector without membranes. After each step, the O2 raw signal [V] was recorded for 10 min. The marks were set to the O2 raw signal [V] to evaluate the zero current.
- Figure 1. High zero current test. Upper panel: Zero current is in the range of ±0.00099 V. Lower panel: Zero current is higher than 0.00099 V when the OroboPOS-Connector is connected to the O2k-Main unit and when the OroboPOS is connected to the OroboPOS-Connector, which means that both the OroboPOS-Connector and OroboPOS might have electrical problems. In order to localize the problem, follow the Oxygen_sensor_test#Switch_components_approach from step 3.
