Handy A5 guide

The free, colour 34-page ‘Guide to Low Resistance Measurement’ (available at www.seaward.co.uk/resistance) features tables of wire and cable characteristics, temperature coefficients and formulae to enable the user to select the appropriate measuring instrument and measurement technique.

It includes a helpful section explaining the role and importance of resistance measurement in the manufacture of electronic components, switches, relays, connectors cabling, electric motor and generators and fuses. Information on resistance measurement requirements in the automotive and railway utilities industries has also been featured.

There’s a useful Glossary of Terms at the end of the guide, providing an easy-to-follow explanation of items relating to both bonding and earth resistance, as well as common industry acronyms such as DMM (digital multi-meter), DUT (device under test) and AWG (American wire gauge).
