INST PK CURR  This readout reflects the instantaneous peak current 
value detected at the output. This value is updated 
continuously and does not require a reset operation like 
the PEAK CURR readout. The instantaneous peak 
current does not use a track and hold mechanism like 
the PEAK CURR measurement in the MEASUREMENT 2 
screen. Instead, it tracks the peak current on a cycle-
by-cycle basis. The INST PK CURR typically tracks the 
rms current and the crest factor. 
UPDATE PROGRAM FUNCTIONS FROM MEASUREMENT SCREEN 
The Shuttle can be used to update program parameters such as voltage, 
frequency or current from the measurement screen.  This can be achieved with 
the following sequence: 
1)  Select the program 1 screen using the PROG key. 
2)  Use the up and down key to select the desired  function to 
update. (Selects parameter that will be changed by the shuttle 
once in the MEAS1 screen) 
3)  Select the measurement 1 screen by pressing the MEAS key. 
4)  The pointer symbol () points to the programmed parameter 
(V, F or CL) that will be affected by turning the shuttle.
