Measure current in the calibration lab
-- Test & Measurement World, 10/1/2008
Fluke’s A40B precision current shunts let metrology and calibration labs produce current measurements from 1 mA to 100 A, producing 0.8 V at rated current. Comprising 14 shunts with cables and connectors, the A40B series can be used to measure AC or DC current with a precision voltmeter, AC measurement standard, AC/DC transfer standard, or thermal voltage converter.
The A40B set consists of four enclosed shunts (1 mA to 50 mA) and 10 radial shunts in three sizes: small (100 mA to 2 A), medium (5 A to 20 A), and large (50 A to 100 A). The shunts use a fin design to minimize thermal drift and interference from external magnetic fields. Their low inductance lets the shunts operate from DC to 100 kHz with minimal phase distortion.
Prices: individual shunts—$1850 to $9995; set of 14 shunts with cables, adapters, and a transit case—$47,495. Fluke, www.fluke.com.
