HI/LO Limit Evaluation
Values from 0 Ωto 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.
