ach standard is small, light and rugged, ideal for shipment. The long 72-hour battery life allows the 732B to be shipped over long distances under power. An optional external battery and charger extends battery life still further, to more than 130 hours.
The 732B can stand up to a lot of abuse. The inputs can be shorted indefinitely and are protected up to 1100V dc, 25 mA, without damaging the cell or affecting its output.
The 732B is based on the proven technology of the 732A, the first standards lab quality electronic reference to gain acceptance as a replacement for saturated standard cells. Originally designed for internal transfers of the Fluke Calibration corporate volt to the production floor, thousands are now in service world-wide in a variety of applications — from maintaining an institutional reference to transferring values from national labs or privately-operated 10V Josephson Arrays.
Stability for each output is ±2 ppm per year (10V) and ±0.8 ppm per month (1.018V). Each 732B can drive up to 12 mA of current to simplify use with instrumentation – like the 5700A – with low output impedance.
Support for artifact calibration
Combined with the 742A-1 and 742A-10k Resistance Standards, a single 732B makes a tough and compact artifact calibration support package for instruments like the 5700A/5720A Calibrators from Fluke Calibration or the 3458A Multimeter from Hewlett-Packard.
732Bs can be ordered with or without calibration certificates. The standard 732B comes without any formal traceability or any calibration certificate. Optionally a calibrated 732B can be ordered and requires both shipping in a “power on” condition (there are limits for the overall shipping transportation time). The model 732B/H is a 732B which ships with a Report of Calibration showing the deviation from nominal and the uncertainty at the time of the calibration. The 732B/C is similar to the 732B/H, but it adds a drift rate characterization report. This is a 12 month projection into the future from the time of calibration of the changes in the calibrated output value.
The 732B is a direct voltage standard with 10V and 1.018V outputs. The 734A is a direct voltage reference standard that consists of four 732Bs that are mechanically and electrically isolated, housed in a rack-mountable enclosure.
