Ω

 to 1510 

Ω

 may be preset for automatic comparison. If the 

measured value is outside of the limit an audible and visual signal is given.

Recording

Measured values can be saved or logged with a defined time interval from 

1 to 255 s. Recorded values may then be recalled on the display of the 

instrument.
