Problem testing a iKasu 6 Socket Surge Protector

[gaz]

Any chance of some help on this one Seaward, It's only a matter of time before I (and others) find another lead and have the same problem

It looks like its a popular problem as there's been over a 1000 views of this topic

Looking at the manual online (http://www.pattesters.co.uk/resources/files/primetest-350-manual-45.pdf page 108) it seems to say that the default setting for insulation fail is <1 megOhm, as it should be, and that the maximum is 10 megOhm implying that setting it above 24 megOhm is impossible.

Just to add to the uncertainty, if you look at page 97 of the manual, it says that the IR test display ranges are:
0.00 - 1.99 MΩ
2.0 - 19.9 MΩ
20 - 199 MΩ
which kind of disagrees with page 108.

Gaz: i think you just need to bite the bullet, and edit a test sequence to give you an upper display limit on the IR test of 199 MΩ. Then, hopefully, your results of 24 MΩ should quite rightly record as a PASS. Maybe...

There is a difference in what is DISPLAYED and what the Pass/Fail setting is..

P/F is 0.01 to 10 with a default of 1.

Display is 0.00- 1.99
2.0-19.9
20-199

BOTH are correct.

Yes, I know, Alan, but that wasn't my point.
With an IR test, the pass limit doesn't (shouldn't) have any bearing on the maximum resistance the unit can display.
Pages 97 and 108 still appear to contradict each other.
Only one can be correct.

With an IR test, the pass limit doesn't (shouldn't) have any bearing on the maximum resistance the unit can display.

I still agree with BOTH statements.

Page 98 reports that the P/F level is "User Defined. P109 just gives the values this can be set to - default 1.

Display ranges 0-1.99, then auto range change to 2-19.9 then auto range change to 20-199. The range used all depends on the actual result obtained. This is the same as all auto range multimeters.

There is no "setting the range". With an item just on the P/F border, this would be automatically ranged on the lowest range. With a good IR, the tester goes to the highest range AUTOMATICALLY and displays 199.
