4.4 Measurement of protective lead resistance using 10/25 A cur-
rent
Keep pressing R
PE
button, until the screen in-
forming about the readiness for measurement
with desired current in desired configuration is
displayed.
Symbol indicates that 10/25,
two-wire measurement is set,
symbol indicates that three-
wire measurement is set, symbol
indicates that four-wire meas-
urement is set. Another pressing
of
R
PE
results in switching current
values and measurement types.
When parameters must be changed press
SET . Setting is performed as in section 4.2.
Notes:
Note that any kind of adapter add extra resistance and thus the measurement
result will be overestimated.
- For 10 A and 25 A current, there is no possibility of continuous measurement settings (Cont.) If such
setting was set for the 200 mA current, then switching the meter to measure with 10/25 A current
causes that a default value of 5 s. is set as measuring time.
- To avoid excessive heating of the measuring pin in PE socket, do not trigger the measurement with
25 A current at short intervals.
- The method of measurement and other observations are the same as for the measurement of
200 mA.
