The Megger DLRO 10X digital microhmmeter, suitable for low resistance measurement, is fully automated and selects the most suitable test current up to 10 A DC to measure resistance from 0.1 µΩ to 2000 Ω, on one of seven ranges. It is available to rent.
This small, lightweight and portable instrument uses a menu system controlled by a two-axis paddle to allow the user to manually select the maximum test current.
Its features include: auto current reversal cancels standing emfs; protected to 600 V; automatically detects continuity in potential and current connections; multiple operating modes including fully automatic; alpha-numeric keypad for entering test notes; user selectable high and low limits.
It uses the four terminal resistance method, which shows the true resistance of the item under tests. It also automatically applies forward and reverse currents which cancel out any standing voltages across the sample under test.
