Step 2: Set compliance limit
Perform the following steps to edit the compliance limit value:
1. Press the LIMIT key.
2. Move the cursor to the digit to change, then press the navigation wheel
mode, as indicated by the EDIT indicator.
3. Enter the desired limit value, then press the ENTER key or the navigation wheel
editing.
Step 3: Select measurement function and range
Select measurement function and range as follows:
1. Select the desired measurement function by pressing MEAS or MODE.
2. Set the desired measurement range with the RANGE keys, or enable AUTO RANGE, keeping
the following points in mind:
•
When measuring the source (such as when sourcing V and measuring V), you cannot select the
measurement range using the RANGE keys. The selected source range determines the measurement
range.
•
When not measuring the source (such as when sourcing V but measuring I), measurement range
selection can be done manually or automatically. When using manual ranging, use the lowest possible
range for best accuracy. When autorange is enabled, the Model 2651A automatically goes to the most
sensitive range to make the measurement.
Step 4: Turn output on
Turn the output on by pressing the OUTPUT ON/OFF control. The OUTPUT indicator light will turn
on.
Step 5: Observe readings on the display.
Observe the readings on the display. Press the TRIG key if necessary to trigger the instrument to
begin taking readings. The readings are on the top line, while source and limit values are on the
bottom line.
Step 6: Turn output off
When finished, turn the output off by pressing the OUTPUT ON/OFF control. The OUTPUT indicator
light will turn off.
Remote source-measure procedure
Basic source-measurement procedures can also be performed by remote. To do this, send the
