12.   When the meter is in the graphical mode, press “

MIN/MAX

” to capture a 

waveform display to the PC screen. 

NOTE:

 Capturing a waveform will delete any active recorded data. To save any 

recorded data, save it before using “MIN/MAX” to capture or capture the screen to the 
MultiScope memory for later recall. 

CAUTION

: Always observe the MultiScope LCD display for overload conditions. If an 

overload occurs, the MultiScope software displays the maximum value for the range 
selected. It does not indicate an overload on the PC screen. i.e. If the 40V range was 
held and a voltage greater than 40V was applied to the test leads, the PC display will 
indicate “40.00”, not “OL” or the actual voltage. To avoid this condition, Autoranging is 
recommended
