Megger DET4TCR2 Description
Megger DET4TCR2 (1000-346) 4-Terminal Ground Resistance Tester Designed for extended temperature range use, this digital ground tester features a rechargeable battery. Easy-to-use, this ground tester offers the basic functions required for ground system testing, including variable frequency 2, 3, and 4 poles, Attached Rod Technique (ART), ground noise voltage measurement, and more. Designed to negate the need for a shorting link when making two-pole measurements, this ground tester also offers labeled auxiliary controls used to select the test frequency (94, 105, 111, and 128 Hz), output voltage (50 or 25 V where local standards apply), and to switch the backlight on or off.
Features:
- Stakeless testing capability - Allows the operator to use the instrument like a clamp-on tester in applications where the method is viable
- Attached Rod Technique capability - Allows fall of potential testing without the need to disconnect the ground rod
- Multiple user selectable test frequencies allows the operator to find the most effective frequency for making the measurement
- 200,000 Ω measurement range provides the ability to measure the resistivity of any type of soil
- User selectable test voltage ensures that the units can be used in agricultural environments
- Microprocessor control for improved error detection
- Clear, unambiguous warnings and error indications ensure the reliability of the reading and reduce test time
- Rugged, weatherproof case to IP54
- Backlit LCD allows for testing in dark environments
- Noise rejection to 40 V pk to pk allows accurate testing in noisy environments
- Accuracy of 2% of reading enhances reliability of measurements
- Voltmeter function allows you to measure the ground voltage and enhances operator safety
- CAT IV 100V provides increased operator safety
