    Notes
    [1]for maximum battery life recommend the use of alkaline cells.
    [2]lower limiting frequency specified for an output load impedance of 1 MΩ
    [3]when using a power supply that is Sensor supply voltage is limited by the voltage provided by the PSU.
    [4]1 MΩs output load
    [5]sensor connection either via BNC connectors or 4-pin female (simultaneous use not possible). Unused connectors should be covered by the supplied vinyl caps.
