Megger DLRO10HD Digital Low Resistance Ohmmeter, 10-Amp

Description

The Megger DLRO10HD is a 10-Amp digital low-resistance ohmmeter designed for accurate and reliable resistance measurements in harsh environments. It is suitable for applications such as checking welded joints, electrical bonds, and motor winding resistance. 

Key features

• Heavy-duty casing: The DLRO10HD is housed in a rugged case with an IP65 rating when the lid is closed and an IP54 rating during battery operation, making it durable and suitable for all weather conditions.
• Dual power supply: The unit can operate from a rechargeable, sealed lead-acid battery or via a mains power supply, allowing for continuous testing even if the battery is depleted.
• Five test modes: A simple rotary switch allows you to select from five different test modes, including:
• Normal: Initiates a forward and reverse current test by pressing the 'Test' button.
• Automatic: Starts the test automatically as soon as the probes make contact, ideal for rapid testing.
• Automatic Unidirectional: Provides faster measurements by applying current in only one direction. However, this may be less accurate due to thermal EMFs.
• Continuous: Provides repeated measurements every three seconds on the same sample.
• Inductive: Specifically designed for testing inductive loads like motors and generators, and it will continue to pass a current until the voltage stabilizes.
• High and low power options: The ohmmeter offers user-selectable high and low power ranges for different diagnostic needs.
• Safety features: Includes protection against accidental connection to external voltages up to 600V and a live voltage warning light.
• Clear display: The large, backlit LCD display is easy to read, even from a distance, and features an oversized 5-digit main display.
