Basic SourceMeter operations
Fundamental SourceMeter operations include source-measure, measure only (V or I), and
measure ohms.
Source-measure
There are four source-measure combinations for the SourceMeter:
Source V, Measure I
Source I, Measure V
Source V, Measure V
Source I, Measure I
The basic procedure to source-measure is provided in Table 3. It assumes that the DUT is
already connected to the SourceMeter as explained in Basic connections.

Source-measure procedure
Procedure Details
1. Select source function. Press SOURCE V or SOURCE I.
2. Set source level. Use DISPLAY EDIT key to place cursor in source
field (Vsrc or Isrc), use RANGE  and  keys to
select range, use edit keys to key in source value,
then press ENTER.
3. Set compliance limit. Use DISPLAY EDIT key to place cursor in Cmpl
field, use RANGE  and  keys to select range,
use edit keys to key in limit value, then press
ENTER.
4. Select measurement function. Press MEAS V or MEAS I.
5. If not measuring the source, select
measure range or use auto range (see
Notes 1 and 2).
Use RANGE  and  keys to manually select
range. Or press AUTO RANGE (AUTO annuncia-
tor on) to enable auto range.
6. Turn output on and take readings
from display.
Press ON/OFF OUTPUT key. OUTPUT indicator
on.
7. Turn output off when finished. Press ON/OFF OUTPUT key. OUTPUT indicator
off.
Notes:
1. When measuring source (i.e., Source I, Measure I), you cannot change the measure range or enable auto
range. The measure range is determined by the source range.
2. When not measuring the source (i.e., Source I, Measure I), the compliance range determines the maximum
measurement range that can be selected.
