5070 Ductor Tester and Micro-Ohmmeter Calibrator

Description

The 5070 DuctorCal is a portable instrument suitable for calibrating high current

ductor testers and micro-ohm meters. It incorporates 5 sets of high current

standard resistors that are used to enable precision calibration.

It 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.

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.
