OPERATING MANUAL PAT-800/805 version 1.09 25
- For 10A and 25A current, there is no possibility of continuous measurement settings (Cont.) If such
setting was set for the 200mA current, then switching the meter to measure with 10/25A 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
25A current at short intervals.
The method of measurement and other observations are the same as for the measurement of
200mA.
Additional information displayed by the meter
Non-continuity in the test circuit during the measurement
4.4.1 Two-wire measurement of protective lead resistance using 10/25A
current (only PAT-805)
Connect the mains plug of the tested device into the test socket of the
meter. Use the probe connected to socket
I2 and touch metal parts of the
tested device connected to PE.
The method of measurement and observations are the same as for the measurement of 200mA.
