The line power cord must be disconnected before opening the instrument To gain access to the inside remove the six screws from the bottom of the transportable enclosure. Once removed, unscrew the two top bolts to provide a grip for extracting the entire calibrator assembly from the transportable enclosure (this is one self contained assembly).

    9000 SERIES OPERATION MANUAL Main analogue amplifier and feedback board This board generates AC and DC voltages and currents which are derived from the D/A boards 0 to 10Volt reference. This reference voltage is compared against the output after it is scaled from either a precision resistive divider of switchable gain for voltage ranges or from a set of precision current shunts for the current ranges.

    9000 SERIES OPERATION MANUAL High Voltage Amplifier and Output All outputs above 20 volts use this amplifier. A high power 150W IC amplifier running from 25 volt supplies with thermal and output overload protection output is switched into either a high frequency ferrite transformers or a LF iron laminate transformer depending on the frequency to produce all high voltage outputs.

    9000 SERIES OPERATION MANUAL Output Currents Sensing & Shunts Six high stability current shunts with low temperature coefficients from 4kOhms to 0.01ohm provide feedback for the current ranges. The lower values are switched using a four wire method for optimum accuracy, there is no provision for the adjustment of the value of the shunts, calibration is performed by the calibration factors.

    Calibration Tutorial Getting the best out of the calibrator. The 9000 series are very accurate calibrators producing a very wide range of output signals. To make the best possible use of the range of outputs and to eliminate errors this section details some common sources of errors and offers some techniques to reduce them.
  • Page 104 9000 SERIES OPERATION MANUAL Power line and low frequency Pick up and noise These effects are most noticeable when using high resistance (100kohms and above) and low current. All constant current sources have a very high output impedance which will pick up noise just like the high value resistance . To reduce pickup, use screened leads and try earthing the low side of the calibrator output.
