Abstract
High-Accuracy Microhmmeters Have Versatile Measurement Capabilities
The Cropico DO4000 series of handheld digital microhmmeters from Seaward provides a highly practical solution for a wide range of low-resistance measurement applications in the precision engineering and manufacturing sectors.
The portable and rugged instrument range includes a number of advanced features to ensure high measurement accuracy including forward and reverse current measurements with auto-averaging, true current zero, long scale length and a selectable measurement range from 40 mΩ to 4 kΩ with respective resolutions between 10 µΩ and 1 Ω.
Within the three model series, the DO4001 also includes temperature compensation, with preset coefficients for copper and aluminium plus user-settable coefficients for other materials. Temperature measurement over the range −50 to +800 °C is also available.
Protection up to 415 Vrms is provided at the measurement terminals, and push button operation is achieved easily by clearly marked function controls. Direct reading measured values are displayed on a four-digit liquid crystal display (LCD) display.
Over-range and low-battery indication is also provided, and warning light-emitting diodes (LEDs) illuminate when an open circuit lead condition is detected.
The Cropico DO4000 series comes complete with a standard 1-m length lead set, and a rechargeable battery option includes a battery pack, docking station and charger.
The DO4000 series forms part of a comprehensive range of Cropico instrumentation available from Seaward for precision measurement applications.
