  • Page 12 Description of the instrument Description of the instrument (cont’d) Advice for use of the sensors Distribution of stray capacitors: Connection of the reference conductors to the sensor It is imperative, considering the stray capacitances, to correctly connect the reference conductors for each sensor. The conductors should preferably be connected to the cold points to avoid the transmission of noise by the stray capacitance between modes.
  • Page 13 Description of the instrument Description of the instrument (cont’d) The calibration output (3 Vpp, 1 kHz) for the sensors is underneath the Sensor calibration battery cover (see p. 10). To obtain optimum response, the sensor's low frequency compensation must be adjusted. To carry out this adjustment, the two channels of your oscilloscope must be disconnected from the measured circuits before opening the battery housing cover.
