Ready for the 17th Edition 3rd Amendment
The ET4000 has built-in loop pass values which are set to the new values as required in the 3rd Amendment to the 17th Edition wiring regulations.
Simple pass / fail indication
A red & green LED indicator gives an instant notification of a pass or fail, based on the selected pass limit.
Keep your firmware up to date
A key advantage of the Martindale ET4500 is the ability to update the firmware yourself. If further changes are made to the 17th Edition testing regulations, you can update your tester without having to return it to the manufacturer.
Auto RCD test results displayed simultaneously
Most other MFTs require you to scroll through the 5 test results of an auto sequence. The ET4000 displays all the results on screen simultaneously, saving time when recording the information.
Earth ground resistance test
With this tester you can perform a 3 wire ground resistance test with the optional earth spike kit.
Automatic wiring check
When connected, a wiring and polarity check is automatically carried out. This helps identify potentially dangerous wiring faults in advance.
True RMS voltage measurement
Did you know how important true RMS readings are? Standard RMS measurement only gives an average reading and with anything other than a perfect sinewave, this reading can be as much as 50% out! With true RMS, you get an accurate measurement. Whereas this feature is only available in the top model from most other manufacturers, it is included as standard with the Martindale ET4000. This true RMS reading will ensure your recorded voltage levels really are within the new Cmin limits defined in amendment 3.
User settable pass limits
Some installations may require testing to specific pass values. The ET4000 allows you to set these limits manually, ideal if you have a number of engineers testing a site, or if you are training an apprentice.
CAT IV safety rating
Safety is paramount when it comes to testing. Using a tester on a system that it is not rated for can lead to serious injury or death. The ET4000 carries a CAT IV safety rating, offering a high level of user protection.
Easy to replace test leads
Having a test lead fail on a job can be a real headache. If you can't obtain a replacement quickly, you can lose time on a job. The ET4000 comes supplied with standard 4mm banana leads, this means you can easily get replacements from your local wholesaler if you need them urgently.
Rechargeable batteries as standard
Rechargeable batteries and mains charger are supplied with this tester as standard. The ET4500 has a built-in charger, so no need to remove the batteries. A safety lockout function ensures you cannot charge the batteries whilst carrying out tests. An optional in car charger is also available.
