    2. DESCRIPTION OF THE INSTRUMENT 2.1. PRESENTATION The particularity of these oscilloscopes is that they group 3 instruments in one: „ a laboratory digital oscilloscope for the analysis of electronic and electrotechnical signals, „ a 2-channel, 8000-count multimeter, „ a harmonic analyser, for the simultaneous decomposition of 2 signals with their fundamental and their first 31 harmonics. The instrument operates at a constant acquisition depth of 2,500 points.
  • Page 8: Channel Insulation

    2.3.1. CHARGE The batteries are charged when the oscilloscope is powered off but connected to the external power supply. During the fast charge of the batteries, the front-panel LED is on. It flashes in the following situations: „ pre-charge of very flat batteries „...
  • Page 9: Ca 922 & Ca 942

    The use of accessories with a voltage and/or category lower than 600 V CAT III reduces the operating range to the lower voltages and/or categories. Your oscilloscope is rated 600 V CAT III; at least 600 V CAT III accessories must be used. The accessories shipped with the instrument allow this.

CONNECTION OF THE REFERENCE CONDUCTORS TO THE SENSOR Distribution of stray capacitors: 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 11: Sensor Calibration

    The noise of the digital ground (earth) is sent to the analogue input by the stray capacitance. Reminder: In order to prevent electric shocks or possible fires: Never use accessories on which the casing is accessible if it has a voltage of > 30 Vrms compared to the earth. This precaution is necessary for example for sensors with an accessible metal BNC.
  • Page 12 Select the DC coupling for the channel to which the sensor is connected and run an autoset (icon opposite) to carry out pre-setting. Adjust the sensitivity and the vertical offset of the channel so that the signal fills the screen, and adjust the time base to 200 µs to view a signal period on the screen.

  • Page 27 Example 1: M = A + B, addition of a 5 Vpp sine with a 5 Vpp square almost in phase: In our example the amplitude of the resulting signal is 10 Vpp. As the sensitivity of channel M is 1 Vpp, it can be seen that the trace overshoots but is contained on the screen by dividing the representation by 2: The sensitivity of the M channel becomes 2 V and the amplitude remains at 10 Vpp.
  • Page 28 Example 2: M = A x B, multiplication of a 5 Vpp sine and square almost in phase: In our example, the peak amplitude of our mathematical function is 2.5 V * 2.5 V = 6.25 VV. As the channel M sensitivity is 1 VV (with the factor x 1), it can be seen that the trace overshoots and can be corrected by using the /2 coefficient.
  • Page 29 Example 3: M = A ÷ B, division of a 5 Vpp sine and square almost in phase: As the positive voltages of signals A and B are equal, the division leads to a positive peak voltage of 1 V/V, and therefore a representation of 1 division on the trace.
