INDICAtOrS Of LImItS Of uSE
After the measurement has started there are indicators of when:
The values R
H
and/or R
S
are too high
The measurement current I
H-E
is too low
Measurement instability is high
Those conditions that may give uncertain results are indicated on the display of the unit as follows:

(1) Not active if the SMOOTH function is selected.
(2) The symbol
may also appear if there is an external voltage > 42 V on the terminals of the
device.

You should change to manual mode and modify the measurement voltage and/or frequency to
make a valid measurement (when the NOISE symbol is no longer illuminated).
