METRAHITT-COM PLUS
Cable Multimeter for Measurements
in Symmetrical Copper Cable Networks
Characteristic Values
1)
15 ... 45 ... 65 Hz ... 10 (5) kHz sine. For influence see page 4.
2)
At 0to + 40 C
3)
Display of up to max. 5.1 V, “OL” in excess of 5.1 V.
4)
Applies to measurements at film capacitors and with 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. 6 x 10
6
V x Hz: e.g. max. 600 V 1 kHz
7)
Overload capacity of the current measurement input:
See current measuring ranges for maximum current values.
8)
Input sensitivity, sinusoidal signal, 10% to 100% of the voltage or current
measuring range; limitation: up to 30% of the range at up to 100 kHz in the
mV measuring range, 50% of the range at up to 300 kHz, 30% of the range in the
1 A measuring range.
The voltage measuring ranges with max. 30 kHz apply in the A measuring range.
9)
Plus sensor deviation
10)
With ZERO function active
11)
With short circuited terminal tips
Exception: residual value of 1 to 10 digits,
in the mV/A range,
1 to 35 digits as zero point due to the TRMS converter
Key: R = measuring range, d = digit(s), rdg. = measured value
