Preliminary Specifications
99100A
Capacitance Reference System
Industry Leading Reference for Ratio Calibration of Capacitance Measurement Instruments!
GUILDLINE INSTRUMENTS MODEL 99100A CAPACITANCE
REFERENCE SYSTEM provides for ratio calibration of
Capacitance Measurement Systems.
The model 99100A Capacitor Reference System
comprises a number of highly stable hermetically
sealed capacitors with a switch array and a variable
high voltage supply. The unique design allows the
instrument to be used as a reference for ratio
calibration of capacitance measurement instruments.
Provision is made for an additional external reference
capacitor and also for additional extension of the
switched array range with another bank of reference
capacitors.
The switched array and power supply are housed in a
bench top rack cabinet assembly with room for
expansion. The switch array allows various
combinations of capacitance to be connected in
parallel to one of two output connectors. It is only the
low side of the capacitors that are switched.
