Megger’s popular 4-terminal ground testing instrument family includes four basic models with different kit variants for each that include select accessories for greater testing flexibility.
The four basic units are: Model Description DET4TD2 Dry-cell battery powered basic 4-terminal tester DET4TR2 Rechargeable battery powered basic 4-terminal tester DET4TC2 Dry-cell battery powered 4-terminal tester with selectable test frequencies, greater measurement sensitivity and attached rod technique and stakeless measurement capability DET4TCR2 Rechargeable battery powered 4-terminal tester with selectable test frequencies, greater measurement sensitivity and attached rod technique and stakeless measurement capability
The top-end models (DET4TC2 and DET4TCR2) include a current measuring function for ART (Attached Rod Technique) testing capabilities. With this added function, on-site grounds can be tested separately without having to remove the utility connection (as explained further in this document). They also provide stakeless testing capability. This method allows the operator to use the instrument like a clamp-on ground tester in applications where that method is viable, while also being able to operate as a fall of potential tester if required.
Overview
- Stakeless testing capability, which allows the operator to use the instrument like a clamp-on tester in applications where the method is viable
- Attached Rod Technique capability, which allows fall of potential testing without the need to disconnect the ground rod
- Multiple, user selectable test frequencies allow 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 makes the units truly outdoor instruments
- Backlit LCD allows for testing in dark environments
- Noise rejection to 40 V pk to pk allows accurate testing in noisy environments
- Testing kits and certificates supplied — everything needed to start testing immediately
- Accuracy of 2% of reading enhances reliability of measurements
- Voltmeter function included allows you to measure the ground voltage and enhances operator safety
- CAT IV 100V provides increased operator safety
