Megger DET4TD2 Description

Dry-cell battery powered and highly reliable, this ground tester automatically checks the connection and conditions of the P spike, C spike, and the level of ground noise, indicating the status on the display. The tester also offers a voltmeter to enable the measurement of ground voltage.

Features

2, 3 and 4 point testing
Multiple, user selectable test frequencies
Warning indicators prevent test failure
Simple one button operation
Multiple, user selectable test frequencies allows the operator to find the most effective frequency for making the measurement
200,000 ?¦ 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
Accuracy of 2% of reading enhances reliability of measurements
CAT IV 100V provides increased operator safety
