Features
 • Interchangeable test lead terminations
 • High or low output power selection for condition diagnosis
 • Rechargeable battery or line power supply, continuous operation, even with dead battery
 • 10 A for 60 seconds, less time waiting to cool
 • Protected to 600 V without blowing a fuse, test lead live voltage warning light
 • Heavy duty case: IP 65 lid closed, IP54 battery operation
 • Simple rotary switch selection of five test modes, including auto start on connection

Applications
 • The DLRO10HD measures low resistance values in applications ranging from railways and aircraft to resistance of components in industry
 • Any metallic joint can be measured but users must be aware of measurement limitations depending on application. For example, if a cable manufacturer plans to make resistive measurements on a thin wire, a low test current should be selected to prevent heating the wire thereby changing its resistance
 • Measurements on electric motors and generators will be inductive and require the user to understand the inductive mode and charging process before a correct result is achieved
 • The DLRO10HD is well suited to measuring thick conductors, bonds and quality of welding because of its 10 A range for resistance values up to 250 mΩ

Specifications

 • Safety rating: In accordance with IEC61010-1, CATIII 300V when used with optional terminal cover (details in ordering information)
 • Operating temperature and humidity -10 °C to +50 °C (14 °F to 122 °F) <90% RH
 • Reference conditions 20 °C ±3 °C
 • Storage temperature and humidity -25 °C to +60 °C, <90% RH
 • EMC In accordance with IEC61326-1 (Heavy industrial)
 • Noise rejection Less than 1% ±20 digits additional error with 100 mV peak 50/60 Hz
 • On the potential leads
 • Warning will show if hum or noise exceeds this level
 • Maximum lead resistance 100 mΩ total for 10 A operation irrespective of battery condition
