It  may  become  desirable  to  make  periodic  (timed  measurements)  to,  for  example,  check  the 
drift characteristics at pre-defined intervals for a certain period of time.  You may also want to 
make  continuous  (repetitive) measurements  or  a  fixed  number of measurements.

 

This  can  be 

accomplished using the 

Timed Measurements

 feature of the PR-680/680L. 

Note:  The 

Continuous  Measurements

  feature  should  not  be  confused  with  the 

Measurements to Average

 function.
