Guildline Instruments 4410 Portable DC Voltage Standard (S/N: 580)

Description: 1. Guildline Calibration Services utilized and maintained this unit as its DC voltage standard in Lake Mary, Florida.2. The unit includes sixteen (16) digitized historical calibration certificates performed by Guildline Calibration Services. The one (1) shown in this listing is one of the sixteen (16) certificates.3. The unit includes a digital copy of the technical manual showing the design philosophy, design implementation, materials acceptance testing procedure, operation, performance specifications, and certification procedure.4. Due to packing regulations, the batteries inside will be removed and NOT shipped. You will have to obtain them locally.5. The Guildline Instruments Voltage Standard Model 4410 is designed for calibration laboratories, which must maintain a knowledge of the absolute magnitude of the Volt to within a few parts per million of the National Standard, and where maintaining standard cell arrays would be impractical or inconvenient. The unit is a fully isolated solid-state 10 V and 1.018 V DC voltage standard designed to be robust and portable. Four (4) independent 10VDC and four (4) independent 1.018 VDC outputs are provided, which are derived from a total of thirty-two (32) solid-state references. This makes the Guildline Instruments Voltage Standard Model 4410 particularly well suited to Josephson Junction's direct comparison.6. The following are the key technical details of the unit:Specifications-Long Term Stability: 2 ppm maximum per year-Temperature Coefficient (16 °C to 28 °C): ±0.04 ppm/°C-Noise (RMS): 0.3 Hz to 10 Hz bandwidth < 0.1 ppm-Hysteresis Recovery: < 0.5 ppm after conditioning cycle and battery discharge-Leakage Resistance: Outputs to guard are greater than 1010 Ohms, outputs to the case are greater than 1011 Ohms, and case to guard is greater than 1011 Ohms.
