D05000 series data sheet - .PDF file.

Lawson Fuses is using a pair of D05000 microhmmeters from Seaward to achieve accurate low-resistance measurement during the manufacture of low-voltage and semiconductor protection fuse links at its Ponteland factory in Northumberland, UK.

Products manufactured by the company are used in the UK electricity supply industry, as well as the household electrical goods and industrial control equipment and instrumentation panels markets.

The use of the D05000s as part of the manufacturing process is claimed to enable accurate quality checking to be completed quickly, ensuring that tens of thousands of fuse links produced and tested weekly comply with the relevant standards and correctly function after leaving the factory gate. A dedicated unit is also available from Seaward for laboratory testing purposes.

Designed to handle all testing applications with a single, flexible meter, the D05000 measures from 0.1µΩ to 30,000Ω in eight ranges with manual or automatic selection and ±0.03 per cent accuracy.

Key benefits of product application 

  • Automatic temperature compensation with 20°C referencing or other user-defined settings is a particularly beneficial feature for Lawson Fuses, increasing true measurement accuracy.
  • The D05000 was chosen by technical manager Jozef Zugaj because it is a high-quality product offering flexible functionality. He said: ‘Not only is the D05000 the most cost-effective solution for us but also the best, with functionality greater in terms of the scope of testing range and output. It’s fulfilled our expectations and has impressed with its performance in an extremely demanding, high-quality production environment.’
  • Higher accuracies over a wider measuring range on the DO5000 microhmmeter are combined with greater functionality than other instrument models and programmable current setting in one per cent steps from 10 per cent to 100 per cent with 10A maximum.
  • Component sorting is simplified by programmable Hi/Lo limits and built-in algorithms ensure stable readings for measuring inductive circuits such as windings.
  • The standard unit also has RS232 and data logging functions, storing up to 4,000 readings with date and time stamp and statistical analysis. Interfaces can be added for remote control and integration into automated test systems.
