Fluke tester

driverman · Jun 3, 2015

Hi guys, for those of you into testing a lot, using a Fluke 1652C all in one tester. What does EER 5 mean when testing? I'm told it could mean noise. Could someone explain please?
The test are mainly carried out on larger size distribution cables (longer runs etc) as opposed to domestic installations. Would you say that the flukes are aimed at the domestic market? Thanks

If I remember rightly the error 5 is noise. This means that when your testing for a Zs say, there is equipment plugged/connected still to the circuit and that will affect the result.

Unplug or disconnect

Out of interest, re comment above..............do other testers record noise fault? Or are they able to ignore the noise and and take a reading?

Error 5 does indeed indicate noise, however a work around (provided the circuit isn't rcd protected) is to select the L-N option.
Null the leads, then connect the L to phase and N to earth.
This will give you a fast Zs reading that's proven very accurate on a properly calibrated fluke when comparing those readings with other makes of tester.

The anti trip low current test should not be used for non RCD circuits, the high current test should always be used as the first option.

Agreed Dave,
My post relates to those models in the flook range that don't have the high current option ie the 1651 without b or c prefix.
With those models, if you connect the way I describe, your effectively performing a high current test.
Of course high current is not an option with rcd's in circuit for obvious reasons.

To the OP your Flook 1652C DOES have high current option.

Then those testers are not fit for purpose!

High current testing is possible with RCDs in the circuit using the alternative Zs test method. The only time it's not really possible is with ring circuits.
