Footnotes:
1.Data for three-phase
systems are valid for
symmetric conditions
(0 °, 120 °, 240 °) unless
specified otherwise.
2. For wiring of single-
phase modes see
chapter 7, "Increasing
the Output Power,
Operating Modes" on
page 95.
3.Single-phase mode
(in phase opposition).
4.rd. = reading;
rg. = range, whereat
n % of rg. means: n % of
upper range value.
5.Valid for sinusoidal
signals at 50/60 Hz and
R
load
≤ 0.5 Ω.
6.Values at 20 kHz
measurement
bandwidth, nominal
value, and nominal load.
7.Guaranteed data at
230 V mains for ohmic
loads (PF=1); typical
data for inductive loads.
Refer to section 6.3.4,
"Operational Limits in
Conjunction with Mains
Supply" on page 53.
8.Current amplitude
derating at frequencies
above 380 Hz (see
figure 6-4).
9.For currents > 25 A, con-
nect test object only to
the 4 mm/0.16 " banana
connections and not to
the generator combina-
tion socket.
