Resolution And Accuracy - Megger DLRO10HD User Manual

Overview

Resolution and Accuracy

„ Test current accuracy ±10%
„ Voltmeter input impedance >200 kΩ
„ Maximum lead resistance at 10 A <100 mΩ
Test Current Resistance Range
100 µA 0 to 2.5 kΩ
100 µA 0 to 250 Ω
1 mA 0 to 25 Ω
10 mA 0 to 2.5 Ω
100 mA 0 to 250 mΩ
1 A 0 to 25 mΩ
10 A 0 to 2.5 mΩ
1 A** 0 to 2.5 Ω
10 A** 0 to 250 mΩ
* Basic accuracy stated assumes forward and reverse measurements.
** Higher 2.5 W (1 A) and 25 W (10 A) power outputs (
Inductive or Uni-directional mode can introduce an undefined error if an external EMF is present.
Basic accuracy at reference conditions.
