Enabling the static recording mode (Rec)
The static recording mode stores the maximum, minimum, and average input 
values during a series of measurements in the LCR meter’s memory.
When the input goes below the recorded minimum value or above the recorded 
maximum value, the LCR meter beeps and records the new value. The LCR meter 
also calculates an average of all readings taken since the static recording mode 
was activated.
