METRAHITULTRA
High Resolution TRMS System Multimeter
Characteristic Values
1
Specified accuracy valid as of 1% of the measuring range
2
Specified accuracy valid as of 2% of the measuring range
3
Display of up to max. 4.5 V, above which overload display appears: “OL”
4
Applies to measurements at film capacitors during battery operation
5
Lowest measurable frequency for sinusoidal measuring signals symmetrical to the zero point
6
Overload capacity of the voltage measurement input:
power limiting: frequency x voltage max. 3 x 10
6
V x Hz for U > 100 V
7
Overload capacity of the current measurement input: see current measuring ranges
for max. current values.
8
Input sensitivity, sinusoidal signal: 10% to100% of voltage/current measuring range ;
in the 300 kHz range the specified intrinsic uncertainty applies as from 15% of MR
9
Plus sensor deviation
10
As of a measured value of 7 A, measurement is limited to an ambient temperature
of 30 C or a maximum duration of 5 minutes.
