Testing instructions
- 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.
