*Important Calibration Information:
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘traceable calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible, we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.

This DET4TR2 rechargeable earth tester is ideal for those who are looking for a high-accuracy earth tester instrument that doesn't require you to constantly change the batteries.

DESCRIPTION:

Megger’s DET4 family of ground testing instruments offers a unique solution to your ground rod and soil resistivity testing needs. The standard instrument comes with, test leads, stakes, terminal adaptors for bare wire, batteries and a calibration certificate delivered in a tough polypropylene carry case - everything you need to start testing in one kit.

The ground testers are rated to IP54 making it truly an outdoor instrument. The ground tester has been designed to be easy to use, a large selector switch makes the selection of
2 pole, 3 poles, or 4-pole tests easy with gloved hands - and the design makes the fitting of shorting links to perform 2-pole tests a thing of the past. A large, clear, easy-to-read LCD display and thumb-sized test button again make the instrument particularly suited to the outdoor conditions of ground testing.

In addition to this ease of use the ground tester also automatically checks the connection and condition of the P spike and the C spike, indicating the status on the display. The instrument also includes a voltmeter to allow you to measure the ground voltage. The ground tester can measure resistance from 0.01 Ω through to 20 and earth voltages up to 100 V. To allow testing in noisy environments the instrument is capable of rejecting noise of up to 40 V peak to peak.

DET4TD2 digital ground tester is powered by 8 AA batteries which are widely available and deliver excellent testing time. The DET4TR2 is powered by rechargeable AAA cells. The battery charger is built in and the instruments are supplied with an AC/DC adaptor. For both instruments, the battery status is displayed using a bar graph. The Megger ground testers comply with stringent safety standards and are rated to 100 V CAT IV. They also have selectable 25 V or 50 V output for compliance with IEC
61557-5.
