Current readback autorange
The current autorange function provides four different aspects of autorange behavior to
handle applications which see a frequent variation of current drawn by the DUT. See
also
.
1. Select "Current Readback Autorange" from
.
The "Current Readback Autorange" dialog is displayed.
Figure 6-21: Current autorange dialog
2. To enable the "Current Readback Autorange" function, set "ON" to enable the func-
tion.
Select any of the following to configure the current autorange behavior.
● "Upshift Approach"
The "Upshift Approach" is used if current drawn exceeds the measurement
range (i.e overrange condition). There are two different approaches for the
instrument to switch to a larger range.
Ranges / Digital voltmeter (DVM) / PLC
