High zero current
- In order to localize the problem, the following test should be performed:
- Note: Before sending us the O2k or any spare components, please contact us via our O2k-Open Support system: O2k-Open Support
- Example:
- 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 have electrical problems. 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.
- Example:
