Datasheet
The Megger DLRO10x Digital Low Resistance Ohmmeter is a fully automatic instruments, selecting the most suitable test current up to 10 A d.c. to measure resistance from 0.1 μΩ to 2000 Ω, on one of seven ranges.

For users who desire more control over the measurement process, DLRO10X uses a menu system controlled by a two-axis paddle to allow the user to manually select the maximum test current.

DLRO10X also adds real time download of results and on board storage for later download to a PC.

Features:

  • Accurate results in under three seconds
  • Auto current reversal cancels standing emfs
  • Fuse protected to 600 V
  • NiMH battery reduces weight
  • 250 mW power limit (with optional override) to avoid heating the test sample
  • Automatically detects continuity in potential and current connections
  • Visible warning of high voltages present at the terminals
  • Visible warning of current flowing in the test sample
  • Multiple operating modes including fully automatic
  • Alpha-numeric keypad for entering test notes
  • User setable high and low limits
  • Autoranging with Manual option
  • Printer output and memory
