I really enjoyed this book. It captures the essential challenge people face as they try make sense of their lives and grow to adulthood.

Megger 6410-979 BT51 - Digital Low Resistance Ohmmeter | Measuring Ranges 20 mOhm and 2000 mOhm

Available: In Stock
€2.435,19

Brand: Megger

Properties:

  • Two measuring ranges (20.00 mOhm and 2000 mOhm) - max resolution of 0.01 mOhm
  • High test current 2 A
  • High test current 2 A
  • Four terminal measurement
  • Protected against inadvertent connection to the mains supply

Product description: The BT51 Low Resistance Ohmmeter makes measurements by passing a current through the conductor under test and also monitoring the voltage across it. The test current is limited by a simple current limiting circuit and is measured by monitoring the voltage across a resistor. The test current is maintained at a nominal 2 A, and as the measurement is ratiometric, the reading is unaffected by any current variations.

The BT51/120 ohmmeter is protected up to 240 V AC by a relay circuit that keeps the instrument in a safe mode isolated from the mains supply. This safeguard is effective whether or not the instrument has been switched on.

  • 3.5 digit LED display facilitates operation in poorly lit environments
  • Robust, portable case provides protection from shocks and weather
  • Compatible with very long test leads
  • Powered by internal rechargeable cells

 Examples of using:

  • Commissioning and maintenance of substation equipment, where measurements can be made on such things as busbar joints, switch and circuit breaker contact resistance, fuse resistance, cold lap welded joints in aluminum earthing strip and earth bonding

  • Maintenance of overhead transmission lines, where "hot" joints can be tested before and after their remaking or recompression Bond testing aircraft frames, including the bonding of electronic dischargers and fuel tanks

  • Testing earth bonds in mines

  • Rail bond testing, where a rail is used as part of a communication system or for power transmission

  • Testing the integrity of lightning conductors

Included:

  • 1 Low Resistance Ohmmeter, 120 V (BT51-120)
  • 1 Supply Lead for Battery Charger (25424-860)
  • 1 Set of Duplex Hand Spikes with 8 ft. Test Leads (6111-022)
  • 1 Operating Instructions

Package dimensions: 15.9 x 10.6 x 10.4 inches
