Model 9211A
Multi-Tap, 300A Precision DC Current Shunt
A High Stability Multiple Value Precision DC Current Shunt
GUILDLINE INSTRUMENTS 9211A DC PRECISION CURRENT
SHUNT is a four-terminal bench top or rack mount
instrument designed for convenient measurement of
current in nine ranges from 10 microamperes to 300
amperes. Voltage output at full rated current on all
ranges is 0.1 volt. Accuracy is calibrated at 23 0C, and
referred to the unit of resistance as maintained by the
National Research Council of Canada or the National
Institute of Standards and Technology. A report of
calibration giving the measured values is furnished.
All connections and adjustments are accessible on the
front panel. Separate current and potential terminals
are provided. Range selection is made by means of two
brass plugs inserted in pairs of ports on the panel. A
sturdy Formica case for bench mounting is supplied
with the standard configuration. Alternately, the 9211A
can be supplied with rack mounting brackets. The rack
mounted configuration occupies 222 mm (8.7 in) of
vertical space.
The shunt resistors are mounted in air for minimum size
9211A FEATURES and weight while minimizing self-heating effects.
The 9211A is a Convenient and Excellent
Accuracy to
