Page 41: Measurement Considerations
Operation Measurement considerations Many measurements made with the Model 7013 are subject to various effects that can seriously affect PATH low-level measurement accuracy. The following para- graphs discuss these effects and ways to minimize them. 7013 Measure Card Instrument 4.5.1 Path isolation = Source Resistance of DUT The path isolation is simply the equivalent impedance = Source EMF of DUT... -
Page 42: Magnetic Fields
Operation 4.5.2 Magnetic fields on the measurement can be considerable if enough of the unwanted signal is present. When a conductor cuts through magnetic lines of force, a very small current is generated. This phenomenon RFI can be minimized in several ways. The most will frequently cause unwanted signals to occur in the obvious method is to keep the equipment and signal test leads of a switching matrix system. -
Page 43: Keeping Connectors Clean
Operation 4.5.5 Keeping connectors clean Signal Leads Instrument 1 Instrument 2 Instrument 3 As is the case with any high-resistance device, the integrity of connectors can be damaged if they are not handled properly. If connector insulation becomes con- taminated, the insulation resistance will be substan- tially reduced, affecting high-impedance measurement paths. -
