The High Resistance, 5kV & 10 kV Decade Box (HRRS-5kV, HRRS-10kV)
is a family of high voltage decade boxes that answers the need for calibration and working high resistance decade standards that go up to 10 TΩ. High values of resistance are
available for use at high voltages, without sacrificing accuracy, stability, and
temperature and power coefficients of resistance.
The HRRS-5kV, 10
kV Decade Box offers a broad choice of resistance sources that are
high-range with excellent performance. These high resistance decade boxes employ
state-of-the-art precision resistors of various types. They are designed
specifically for operation at high voltage, with very low leakage to minimize
degradation of accuracy.
The standard models offer a choice of one to
nine decades. The panels are clearly labeled showing the step size and maximum
allowable applied input for each decade. Custom requirements outside of the
standard models can be satisfied.
With a resolution as low as 10 Ω and a
maximum available resistance of 10 TΩ, the HRRS-5kV and 10kV Series may be used
for exacting precision high-value resistance applications that require voltages
of up to 10 kV.
HRRS-5kV & -10kV High Resistance Decade Box
Applications
- •Calibration of meggers and megohmmeters,
- •Checking of electrochemical and biomedical sensors and instruments.
- •Testing high-impedance amplifiers and the insulation of low-power circuits.
