Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual
Basic measurement procedure
The following procedures outline measurements on a generic device under test (DUT).
Output control
Use the ON/OFF OUTPUT key to turn both Model 6482 outputs on or off simultaneously for basic
source-measure operation. With either channel 1 or channel 2 output on, the blue ON/OFF
OUTPUT indicator light will be on. The indicator light turns off when the outputs are turned off.
WARNING
To prevent electric shock, do not make or break connections to the Model
6482 while it is on.
Basic measurement circuit configuration
The circuit configuration for the basic measurement procedures that follow is shown in
.
In this example, channel 1 connections are shown, but channel 2 connections are similar. See
for detailed connection information.

Circuit configuration for basic measurements
Front-panel measurement procedure
Step 1. Select measurement channel and range.
Select the measurement channel by pressing the
MSR1
(channel 1) or the
MSR2
(channel 2) key.
With autoranging turned off, use the RANGE
and
keys to manually select the current
measurement range for that channel. You can also press the
AUTO
key to select autoranging.
Step 2. Select source channel and set source level.
The source level is the voltage setting of the selected source (channel 1 or channel 2).
NOTE
The Model 6482 must be in the edit mode (EDIT indicator ON) to set source values. The
edit mode is selected by pressing the
SRC1
or
SRC2
key. The flashing digit for the
source value in the Src1 or Src2 display field indicates that the Model 6482 is in the edit
mode for that channel. If no editing operation is performed within six seconds, the edit
mode times out and is cancelled.
