Used FLUKE DC Reference Standard
Description
The Fluke Model 731B DC Reference Standard is a versatile instrument providing stability, while utilizing the excellent performance capabilities of solid-state technology. The instrument furnishes a variety of prevision voltages with switched output ranges including 1.0, 1.018 + ΔE, 10.0 and ΔE volts. Delta E (ΔE) provides a variable output of 0 through 999 µV which is either added to the voltage of a standard cell transfer or may be used directly as a low-level, stable direct voltage source.
Key Specifications:
- Output Ranges: 10V, 1V, 10018 + ΔE, 1.019 + ΔE, ΔE
- Output Protection: The output may be shorted indefinitely without damage to instrument.
- Line Regulation: <1 ppm for ±10% line voltage variation
- Ripple & Noise: <1 ppm peak-to-peak 0 to 1 Hz, <20µV rms 1 Hz to 1 MHz, except <70µV rms at 10V output
- Isolation: Output may be floated up to 500 dV between chassis ground and guard
- Temperature: 0°C to 55°C, operating
- Size: 8.8 cm H x 10.7 cm W x 30.4 cm D (3.5 in H x 4.5 in W x 12 in D)
- Weight: 2.26 kg (5 lb)
