Testing instructions
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2013 BMW 335is, 2013 BMW 335i, 2012 BMW 335is, 2012 BMW 335i, and 2011 BMW 335is. However, it is still accessible from the selected car via links, so may be relevant.
- The current clamp must be calibrated before taking the measurement. The current clamp must not be connected to live leads until it has been calibrated.NOTE: At present, calibration has to be repeated every time a setting is changed.
- The current clamp must be connected to the battery negative lead. The arrow on the current clamp must point towards the battery.
- Record mode: Select TIME/DIV: 500 ms/Div. This provides a maximum recording time of more than 24 hours. The shorter the recording interval is set, the more signal changes, e.g. interference spikes, are recorded. For recording over a 24-hour period, the setting 500 ms/Div is recommended.
- Quiescent current can also be measured in "Normal" mode (Record deactivated). However, the display can then only show readings in the indication range covering a period up to 33 minutes (200 s/Div).NOTE: When current measurement is completed in Record mode, the current readings can only be displayed in the ampere range using the cursor at present.
- For all long-term measurements, the ISID and IMIB must be connected to the power supply (power pack).
At present, calibration has to be repeated every time a setting is changed.
