Measurements International has developed the 6314A Precision Current Divider with the aim to replace/ improve the outdated and often inaccurate Current Shunts being used. The 6314A is a 1000:1 Current Divider that works on the principal of the world-renowned MI Resistance Bridge and Extenders. Traditional Current Shunts suffer from temperature stability and power coefficient issues that greatly affect the users ability to make accurate measurements. The current transformer used in the 6314A has no such issues. The 6314A uses the ratio of two sets of windings on a DC Current Comparator (DCC) to divide the input current by 1000. The 6314A minimum current is 150 A, and the maximum current is 3000 A.

The 6314A can accept both DC and AC current with the uncertainty of approximately 20 times less than a DC Current Shunt.

The 6314A can also be combined with the 6311A to reduce very large currents down to mA. For instance, a 6314A can be used to divide up to 3000 A down to 3 A, which can be further divided to 30 mA using a 6311A. In this way a 1 Ω standard resistor and an 8 ½ digit DMM can be used to measure 3000 A with uncertainties of a few ppm.

Since 1993, MI has earned a worldwide reputation for Dependability, Quality, and Performance.

Measurements International has developed the 6311A Precision Current Divider with the aim to replace/improve the outdated and often inaccurate Current Shunts being used. The 6311A is a 100:1 and 1000:1 Current Divider that works on the principal of the world renowned MI Resistance Bridge and Extenders. Traditional Current Shunts suffer from temperature stabilities and the power coefficient issues that greatly affect the users ability to make accurate measurements. The current transformer used in the 6311A has no such issues. Simply apply power and measure the divided output. The 100:1 range has a maximum current of 10A and the 1000:1 range has a maximum current of 300A. Both ranges can accept both DC and AC current to 1kHz with uncertainty of < 5 and < 20 parts in 106 respectively. In comparison, a DC Current Shunt will have a calibration uncertainty of 0.01% or larger in most cases.

Since 1993, MI has earned a worldwide reputation for Dependability, Quality, and Performance. The 6311A uses the ratio of two sets of winding on a DC Current Comparator (DCC) to measure.

Measurements International’s recently launched Artifact Transfer Standard (1330A) is a highly versatile, accurate instrument that meets laboratory requirements for automated artifact calibration (to assign values to internally generated parameters) on calibrators and DMMs.

This process is typically performed using a small number of standards at recommended calibration intervals indicated in the calibrator or DMM manufacturers manual. The 1330A is composed of a temperature-controlled instrument enclosure, three reference standards, and a battery backup. A power supply is external (part of the power cable).

Never before has DC voltage calibration and/or verification of DVMs and calibrators been so easy or reliable. Measurements International’s recently launched 1340A is the metrology industry’s leading choice thanks to its simplistic design, backed with the best features for optimal performance.

Model 1340A is another fine example of MI’s history and world-leading experience in resistance. We invite metrologists and calibration technicians in national, military and third-party calibration laboratories to compare the performance of the 1340A against any products on the market today.

Measurements International’s new Automated Resistance Standard model 1310A is an easy-to-use, cost-effective calibration instrument that will give the military sector, national and third-party laboratories complete confidence in resistance standards. Designed with input from a world-leading National Measurement Institute, customers can be confident this new design offers exceptional calibration results.
