HACS-Z CAPACITANCE DECADE BOX

HACS-Z Capacitance Decade Box. Capacitor Standard.
The HACS-Z Capacitance Decade provides a wide range of capacitance in increments as low as 1 pF and a total capacitance of up to 10,000 μF. 
With its high quality, tight tolerance capacitors, it is an ideal part of a test or calibration system.
The shielding is divided into two different parts: an inner shield that minimizes the low terminal-to-guard capacitance, and an outer shield (the case) that minimizes the detector input capacitance and noise.
When these two shields are connected together, the HACS-Z becomes an excellent
3-terminal capacitance substituter with low zero capacitance.

Accuracy:
A: ±(0.05% + 0.5 pF); ± 0.5% for 100 µF steps.
B: ±(0.1% + 1.0 pF); ± 0.5% for 100 µF steps. at 1 kHz, 23°C, no zero subtraction, measured with a 3-terminal connection. (Calibration at other frequencies is available, and different frequencies may be selected for different decades.) NIST traceable.
