5.9 Low Resistance Measurement Mode (ME Equipment)

Under IEC 60601-1 (1988-12) + am1 (1991-11) + am2 (1995-03), measurement
of resistance of the protective earth conductor is to be made at 25 AAC of
current. The 3155, however, makes this measurement simply using the DC
four-terminal method (at 100 mADC max.).
This measurement is made for Class

equipment only.

Measurement is made by touching either the optional 9461 PIN-TYPE LEADS
or 9287 CLIP-TYPE LEADS to the test point. Measurement is also possible
using RS-232C interfacing with the 3157 AC GROUNDING HiTESTER (max.
31A AC, conforming to various standards), available separately.

Four-terminal method

When measuring low levels of resistance, ordinarily the resistance of the
measuring lead and the connector are included, which results in errors. By
using the four-terminal method, this error can be eliminated.
The resistance measuring circuit measures the drop in voltage at the
prescribed current, and calculates the resistance. As shown in the figure,
however, the input resistance at the voltmeter is extremely high, and all of
current I flows into the measured resistance R

0

. Therefore the drop in voltage

from R

2

to R

3

becomes 0, the voltage E and the voltage drop E

0

at both ends of

the measured resistance R

0

become equal, and the resistance is measured

without the influence of R

1

to R

4

.

(R1 to R4 indicate the measuring lead and connector resistance.)
