  4. New product common philosophy • Intuitive to use • One button operation • Automatic checking to avoid mistakes and poor connections, indicated on display • Complete and ready to start testing kit, including calibration certificate • Competitively priced to sell • Combination of features, benefits and price makes these ground testers the most attractive on the market

  5. New product common features • Based on building wiring housing • Delivered in tough carry case • Includes stake and wire kit with each model • Very high quality large and easy to read LCD • Includes batteries • Has quick start guide on the lid • Easy to use wearing gloves • Comes with calibration certificate as standard • Three year warranty • Avoids language variants for easy stock holding

  6. New Digital Earth Tester housing

  7. Basic specification – DET3TD • 2 terminal test, no links required • 3 terminal earth electrode test • Earth voltage measurement • LCD display • Automatic checking of • Current spike resistance • Voltage spike resistance • Earth noise voltage • Blown fuse • Battery status

  8. Basic specification – DET3TC • 2 terminal test, no links required • 3 terminal earth electrode test • 3 terminal earth electrode test without disconnection using optional ICLAMP (Attached Rod Technique, A.R.T.) • Earth voltage measurement • Earth current measurement using optional ICLAMP • LCD display • Automatic checking of • Current spike resistance • Voltage spike resistance • Earth noise voltage • Blown fuse • Battery status

  9. Measuring current with the DET3TC and ICLAMP

  10. The Attached Rod Technique with ICLAMP

  11. How the A.R.T. technique works • The test works by • Measuring the current flowing through the earth electrode under test that is generated by the the DET3TC at 128 Hz • Ignoring the current flowing from the DET3TC into the parallel connections and other earth currents normally flowing in the electrode under test • This is a huge benefit because • It allows the user to test the electrode without disconnecting it from the system, avoiding the complication of system shutdown or auxiliary temporary electrodes • It means that the connections to the electrode under test can be left un-disturbed

  12. Basic specification – DET4TD • 2 terminal test, no links required • 3 terminal earth electrode test • 4 terminal soil resistance test up to 2000 ohms • Earth voltage measurement • LCD display • Automatic checking of • Current spike resistance • Voltage spike resistance • Earth noise voltage • Blown fuse • Battery status

  13. DET3TA – analogue model

  14. Basic specification – DET3TA • 2 terminal test, no links required • 3 terminal earth electrode test • Earth voltage measurement • Analogue display • Automatic checking of • Current spike resistance • Manual checking of • Voltage spike resistance • Earth noise voltage • Blown fuse • Battery status

  15. Rear connection panels • Terminals colour coded to lead set • ICLAMP unique connector

  16. Common specifications - electrical • Resistance range: 0.01 to 2000Ω • Resistance accuracy: 2% ± 3 digits (Except DET3TA) • Earth voltage range: 0 – 100V • Earth voltage accuracy: 2% ± 2V (Except DET3TA) • Earth current range (DET3TC + ICLAMP): 0.5mA to 19.9A • Test frequency: 128 Hz • Test voltage: 25V or 50V selectable (Factory set 50V) • Earth noise rejection: 40V peak to peak • Battery type: 8 off AA cells • Approximate battery life: 800 consecutive tests • Safety: EN61010-1 CATIV 100V • EMC: EN61326-1:1998 heavy industrial

  17. Common specifications - Mechanical • IP54 • Terminals: 4mm plug type • Dimensions: 203 x 148 x 78mm • Weight: 1kg • Operating temperature range (digitals): -15 to 55°C • Operating temperature range (analogue): -20 to 50°C • Storage temperature range (all): -40 to 70°C • Humidity: 95% RH non-condensing at 40°C

  18. Spares and Accessories • Spare replacement parts • Two earth test stakes: 6220-804 • 3 replacement test leads: 6220-805 (3m,10m,15m) • 4 replacement test leads: 6220-806 (3m,10m,10m,15m) • Accessories • Terminal adaptor set (4): 6220-803 • Used when the customer wants to connect non standard leads without 4mm connectors fitted • Current clamp: ICLAMP • Spare carry case: 5410-409

  19. Accessories – terminal adaptor set

  20. Accessories • ICLAMP • Extra cost • Earth test spikes • Included • Lead set • Included • Carry case • Included • And not shown • Standard calibration certificateincluded

  21. Pricing strategy • To be attractive to customers with a blend of quality, performance and value for money • To be attractive to distributors by being profitable and easy to stock

  22. Features and benefits • Delivered in hard carry case • Everything you need in one box • Customers will probably leave the instrument in the case while testing to protect it • Delivered ready to use • Nothing else to buy – batteries, stakes and wire included • Calibration certificate – many users insist on this before use • CATIV rated • Safety class rating in “outdoor” environment required by some customers • LEM Handy Geo only specified to CATII

  23. Features and benefits • Unique to new family at this price level • Attached Rod Technique – currently the LEM GEO-X is the only other product that offers this at a far higher price and as part of a much more complex instrument • No external links required for 2 terminal testing – nothing to lose and nothing to forget • We are strong with • Battery status indicator – not just a “low” warning • IP rating 54 – only equalled by Kyoritsu • Temperature range – the widest • Voltage reading (LEM 30V against our 100V) • Best noise rejection • Equal best accuracy with Alphatek and Extech

  24. Features and benefits • We are strong with • Using 128Hz as our test current – close to mains frequency but easy to detect. Industry standard • 2000 ohm measurement maximum • Instructions on tester • Stake and wire kit included • Conclusion • We have the best blend of specification, included accessories, ease of use and price on the market

  25. A few potential customers • Specialist earthing contractors • Large electrical contractors • Electricians in markets with significant domestic and light industrial T T systems • Maintenance companies and personnel • Insurance inspect/test Engineers • Utilities • Mobile/radio communications infrastructure test and installation contractors

  26. Available? • New family in stock Dover now except..... • DET4TD available end of November • DET62D • Declare intention to be made obsolete December 2005 • Last orders accepted December 2006 • Repaired and calibrated for a further 5 years.
