• The 6237 DLRO is a "full feature professional instrument". The RUGGED and "O-RING" SEALED Digital Low Resistance Ohm and Contact Meter is specially designed to measure very low resistance accurately and display the results directly on the large and clear LCD. The 6237 DLRO makes measurements by passing a constant current through the device under test (generally a conductor, contact or low resistance) and measuring the voltage across it. The low resistance is then calculated by Ohm's law.
• This superb instrument is powered by rechargeable battery. It is supplied complete with an instruction manual and test report/QA certificate. This ensures that every product is not just fully functional and calibrated after the assembly lines, but also within tight specification tolerances before leaving the strict quality control of Standard Electric Works.
• It has visual LED checks for excessive; potential lead resistance (Rp) and current lead resistance (Rc). Should the instrument become too warm, the temperature sensor will shut down the current (1sec Off).
• This instrument is indispensable to laboratory applications and to field applications to measure bonding joints, circuit brakers contact resistance, fuse resistance, testing earth bonds in mines, rail bond when a rail is used as part of a communication system or for power transmission, checking the plating quality on PCBs, contacts of relays, continuity or ring circuits and of protective conductors etc...
