General Radio 1615A Highlights
The GenRad 1620-A Capacitance Measuring System is a self-contained assembly of the GR 1615-A Capacitance Bridge with appropriate oscillator and null detector for measurements at 11 frequencies between 20 Hz and 20 kHz. For applications requiring other or higher frequencies, to 100 kHz, the 1615-A bridge can be supplied separately and the oscillator and detector selected to meet your needs.
- The 1620-A is intended for
- accurate and precise measurements of capacitance and dissipation factor
- measurement of circuit capacitances
- dielectric measurements
- intercomparison of capacitance standards differing in magnitude by as much as 1000:1
- Is an accurate, high-precision bridge for the measurement and intercomparison of:
- standard capacitors
- circuit component capacitors
- dielectric materials
- Capacitance range is: 10E-17 F to 1.11 µF in six ranges, direct reading
- Conductance range is: 10E-06 µmhos to 100 µmhos (two positive ranges, two negative ranges)
- Conductance range varies with capacitance range
- Frequency is approximately: 50Hz to 10kHz
- Dissipation factor at: 1 kHz is 0.000001:1
