Multimeter Section
1)
Display: 3¾ places for capacitance measurement; a different sampling rate can be
selected in the rAtE menu for saving and transmitting measured values.
2)
Only manually adjustable
3)
At 0° ... + 40° C
4)
20 … 45 … 65 Hz … 1 kHz sine, for alternating voltage TRMS
AC
,
measured values < 100 digits are suppressed,
see page 4 for influences
5)
ZERO is displayed for active “zero balancing” function,
maximum correction: 50% MR
6)
Lowest measurable frequency for sinusoidal measuring signals symmetrical to the
zero point
7)
Range 300 mV~: U
E
≥ 40% of upper range limit
3/30/300 V~: U
E
≥ 10% of upper range limit
8)
Plus sensor deviation
9)
Without integrated reference junction;
with internal reference temperature plus error of ±2K
10)
The limits only apply for battery operation
