7.4.7 Polarity test 

Note: 

Ì

  This test is only for use on IEC cables and extension cables. 

Ì

  When testing extension cables, a route back to the IEC port of the instrument 

must be made otherwise the test will fail. 

Ì

  Consider the warnings on the display before starting measurement! 

 
The autotest sequence stops after the polarity test. 
The following actions can be taken to continue or complete autotest sequence: 

 

START...................... Start the polarity test. 

Complete autotest sequence. 

F2 function key...........View polarity test help screens. 
F3 function key ......... Repeat the polarity test. 
F4 function key ......... Skip polarity test. 
F5 function key ......... End the autotest sequence. 
 

7.4.8 TRMS current measurement using clamp current adapter 

Note: 

Ì

  If any of the earth bond resistance tests, insulation resistance tests, substitute 

leakage current tests, leakage current test or touch leakage current test fail or 
were skipped in selected autotest sequence, the TRMS current leakage 
measurement will be prohibited! 

Ì

  Consider the displayed warnings before starting measurement! 

 
The autotest sequence stops after the TRMS clamp current measurement. 
The following actions can be taken to continue or complete the autotest sequence: 

 

START...................... Start the TRMS leakage current measurement. 

Proceed with the next TRMS leakage current measurement (in 
continuous measurement mode only). 
Proceed to the next autotest sequence measurement (in single 
measurement mode only). 

F2 function key...........View help screens. 
F3 function key ......... Repeat the TRMS leakage current measurement. 
ENTER key............... Proceed to the next autotest sequence measurement (in 

continuous measurement mode only). 

F4 function key ......... Skip TRMS leakage current measurement. 
F5 function key ......... End the autotest sequence. 
 

7.4.9 RCD test 

Note: 

Ì

  If any of the earth bond resistance tests, insulation resistance tests, substitute 

leakage current tests, leakage current test, touch leakage current test or TRMS 
current measurements fail or were skipped in selected autotest sequence, the 
RCD test will be prohibited! 

Ì

  Consider the displayed warnings before starting measurement!
