The 5070 is a transportable instrument suitable for calibrating high current ductor testers and micro-ohmmeters. It incorporates 5 sets of high current standard resistors that are used to enable precision calibration.

The unit has full 4 terminal capabilities with extra large terminals for the current connection. Gold plated terminals are used throughout to reduce contact resistance and thermal EMFs. 

It has a substantial maximum continuous current rating, but can also be used with much higher transient/pulse test currents. The internal resistance standards are all high quality manganin types with good long term stability and temperature coefficients.

Rugged and portable, the 5070 is ideal for site calibration work, housed in a safety yellow field case with carry handle.

 

Features

  • Calibrate ductor testers
  • Calibrate micro-ohmmeters
  • 0.2, 2, 20, 200, 2000 mΩ
  • 5 cal points: 0/25/50/75/100 %
  • Gold plated terminals
  • Low thermal EMF connection
  • Portable robust carrying case

 

Specifications

Technical Specification
Range Current Accuracy
50, 100, 150, 200 μΩ 200 A 0.8 %
0.5, 1, 1.5, 2 mΩ 100 A 0.5 %
5, 10, 15, 20 mΩ 30 A 0.2 %
50, 100, 150, 200 mΩ 10 A 0.1 %
0.5, 1, 1.5, 2 Ω 3 A 0.1 %
The currents shown above are the continuous rated for both AC and DC. 
Accuracy specification applies to DC signals.
Higher currents (as generated by pulse driven instruments) can be used with an ON to OFF time ratio of 1:10 or less.
The allowed peak currents are 10 times those specified above, with an upper limit of 1000 A and a maximum applied time of 4 seconds.
At least 1 minute should be allowed between applications for cooling.
It is important to ensure there are adequate low resistance connections to the 5070 current terminals.
