Characteristic Values
1)
Up to max. 5.1 V diode voltage, “OL” (overload) is displayed for higher values.
2)
Smallest measurable frequency for sinusoidal measuring signal symmetric to zero point.
3)
corresponds to 600 V CAT I
4)
Input sensitivity, signal/sine: Hz (V): 10 to 100% MR except for mV: as of 30% MR;
H (I): 20 to 100% MR except for 3 A: as of 30% MR; Hz (clip): as of 30% MR
Key:
d = digit(s), rdg. = reading, MR = measuring range, MUL = measuring range upper limit
