1.2 Description
The 5070 DuctorCal is a portable 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.
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 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.
