  • Page 101: Precautions

    Maintenance and Diagnosis Maintenance and Diagnosis Precautions Please comply with the requirements specified in section 2.1. Causes of Drift The slow change in the zero point of the output Output signal signal during the measuring cycle in the 'DC (Long)' measuring mode is called drift.
  • Page 102 Action: First check whether the 'DC (Long)' measuring mode is set. If the problem persists, the cause is due to poor insulation resistance of the range capacitor. To fix this problem, the instrument must be sent in to the Kistler distributor for repair. Cause 2 In this case, the output drifts linearly in the positive or negative direction.

  • Page 103: Testing And Calibration

    As already described above, the Charge Amplifier can also be calibrated with a DC reference voltage source and a calibration capacitor. Calibration with the Kistler precision charge calibrator Type 5357B can provide advantages. You will find further details in this respect in the data sheet or in the instruction manual for this instrument.

    Traceability must be guaranteed. Kistler offers the follow- ing calibration services: Swiss Calibration Service (SCS) Kistler is accredited as an SCS calibration station (Number 049) for the measurands: pressure, force, acceleration and electric charge. In order to ensure traceability and proven measuring accuracy, calibration devices and methods are regularly checked and updated.

    Charge Amplifier, Type 5080A... 8.8 Charge Amplifier Transfer Function 8.8.1 High-Pass Filter The charge amplifier largely consists of a high gain and highly insulated operational amplifier with the capacitor C connected in negative feedback. As a result of the very high gain, U is reduced almost to zero.
  • Page 109 Maintenance and Diagnosis The frequency response is calculated as follows: ⋅ ⋅ ω ω 2 ⋅ π ⋅ ⋅ ω ω ⋅ ω ⋅ π ϕ − ω ⋅ arctan( A time constant resistor R can be switched in parallel with the range capacitor C concerned (in our example 1 nF).
