  • Page 71 Maintenance and diagnosis 7. 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 signal during the measuring cycle in the 'DC (Long)' measuring mode is called drift.
  • Page 72 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 cure 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 73 As already described above, the Charge Meter can also be calibrated with a DC reference voltage source and a cali- bration 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.
  • Page 74 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.

  • Page 80 Charge Meter Type 5015A... In particular, in the processing of steep pulse signals, it is desirable for the transmission delay to be held constant by the filter for all frequencies. In order to minimize signal distortions, account has been taken of this aspect in the design of the Charge Meter.

  • Page 95 Appendix Transfer mode: ASCII Format with Prefix: 6 Bytes ("+/-nnnn;") Measurands are transferred with the prefix followed by 4 significant decimal places. A semicolon (;) serves as separator to the next value. No decimal point, exponent and no unit is transferred. The values transferred must be multiplied by the range selected and divided by 10 000.
