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:

(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).
