U input [V] limited to: 15,000/Freq [kHz]
Example: U input = 1,000 V
AC
Max. frequency: 15,000/1,000 = 15kHz
In the presence of a DC component: Additional error: (UDC/U measured) x (0.7% L + 70 D)
Example: UDC = 2V, U measured = 5 Vrms
Additional error: 0.28% L + 28 D

, V at 50% of the range:
-
1% for a peak factor < 3.
As soon as the PEAK symbol appears, use the AUTO PEAK mode.
DC current
8.3.
Three possible modes: DC, AC, AC+DC
In DC mode, you can measure a direct current or the DC component of an alternating current.
In the AC and AC+DC modes, you can measure the true RMS (TRMS) value of an alternating current with/without its direct
component (no capacitive coupling in "DC" mode).
Fuse: ex.: SIBA/5019906/11A (10x38-11000-DMI-30kA-CR 1000V, very rapid action).
