1
Data for 3-phase systems are valid under sym. conditions (0°, 120°, 240°).
2
Single-phase model (operation with two phases in phase opposition):
two currents in series, additional adapter SPA1 or SPA 156 recommended.
3
3 phases (3 x 1.25A) in parallel for in-phase operation.
4
rd. = reading; rg. = range, whereat n % of rg. means: n % of upper range value (1.25 A).
5
Values at 50/60 Hz, 20 kHz measuring band width, nominal value and nominal load.
