TRMS Multimeter with Insulation Measurement
Technical Data
1
15 ... 45 ... 65 Hz ... 10 (5) kHz sine. See page 6 regarding influence
2
At 0 ... + 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 battery operated
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 at > 100 V
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 voltage or current measuring
range; limitation: up to 30% of the range at up to 100 kHz in the mV measuring
range., 30% of the range in the 3 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 d at zero point due to the TRMS converter
12
10 minute cool-down period
