 User’s Manual 
With the voltage (V) or current (I) measurement function selected, the TOGGLE 
key lets you display both the current and voltage measurements at the same time. 
It also allows you to toggle display positions of the source and measure readings.
With the ohms (Ω) measurement function selected, the ohms measurement is 
always displayed on the top display. The TOGGLE key lets you display either the 
programmed source value, the current measurement, or the voltage 
measurement on the bottom-left display.
The TOGGLE key is also used to display statistical data on readings stored in the 
data store. This function is performed from the data store RECALL mode.
NOTE If FCTN, REL, or Limits is enabled, the TOGGLE key is disabled.
