7. RA 2-pole, 3-pole Measurements
To make 2-pole or dead-earth measurements, connect a jumper between terminals
H/C2 and S/P2 with the supplied connector cable. Refer to Figure. Then follow steps 1
thru 4 except use only earth electrode and the auxiliary earth electrode with minimum
distance between them of 20 m.
A Select function RA 3-pole. Display is as shown below.
16. Measurement of Resistances
• Resistance Measurement (R~)
This measuring function determines the ohmic resistance between 0.001 Ω and
300 kΩ. The measurement is done with AC voltage. For measurements of very low
resistances a compensation of the connecting leads is suggested (see
“Compensation of Measuring Lead Resistance”).

18. • Resistance measurement (RF)
In this measuring mode all resistances from 0.001 Ω to 3 kΩ can be measured with
DC voltage and automatic polarity reversal as per EN61557-5. To achieve highest
accuracy 4 pole measurements are possible. To balance the extension lead, a
compensation has to be done.
