5.6. POSITION “W ”: LOG, ON-LINE SCOPE, SNAPSHOT, MEMORY, DOWNLOAD
WARNING
The maximum DC or AC+DC input voltage is 1000V and the maximum
measurable DC or AC+DC current is 1000A. Do not measure voltages and
currents exceeding the limits given in this manual. Exceeding these limits
could result in electrical shocks to the user and damage to the instrument.
We recommend holding the clamp respecting the safety area created by the
hand protection (see Fig. 3).
Turn the rotary switch to “
W
”. Insert the red cable into the input lead
V
Ω
and the black
cable into the input lead
COM
, and connect the instrument as described in Fig. 12
WARNING
Insert the cable in the middle of the clamp jaws, in order to obtain accurate
measures.
Use the marks as a reference (see Fig. 2).

:
AC 1P
: P, Q, S, pF, dPf, V, I, THDV, THDI, hV01..hVxx (xx=25 for fundamental
frequency 10..75Hz; xx=8 for fundamental frequency 75..400Hz);
•
AC 3P
: P, Q, S, pF, dPf, V, I, THDV, THDI, hV01..hVxx (xx=25 for fundamental
frequency 10..75Hz; xx=8 for fundamental frequency 75..400Hz);
•
DC
: P, V, I.
5.6.1.1. “Start Log” recording
Upon confirming the “
Start Log
” item, the instrument sets to
stand-by and waits for a recording to start. A recording shall be
started when reaching the following minute as indicated by the
