Resistance Measurement (R
F
)
Measuring method: current- voltage measurement as per IEC61557-4
possible
Open circuit voltage: 20 V DC
Short circuit current: 200 mA DC
Formation of measured
value:
with 4-pole measurement wires on H, S, ES can
be extended without additional error.
Resistances >1 in wire E can cause additional
error of 5m /.
