Perform the following steps to edit the source and compliance values:
1. Press EDIT to enter the edit mode. The flashing digit indicates which reading (source or
compliance) is presently selected for editing. If you wish to edit the other field, press
EDIT again.
2. Use the RANGE

want to set. For best accuracy, use the lowest possible source range.
3. Enter the desired source or compliance value. There are two methods to edit the value:
value adjust and numeric entry.
NOT E
To clear the source value to 0V or 0A, press the MENU key while in the edit source
field.
Value adjust — To adjust the value, use the EDIT cursor keys to place the cursor
•
at the appropriate position, and use the SOURCE
decrement the value.
Numeric entry — When the edit mode is entered, the cursor is located on the most
•
significant digit of the value. From this position, you can key in the value using the
number keys (0 through 9). After each number is keyed in, the cursor moves one
position to the right. If desired, you can use the EDIT cursor keys to place the cur-
sor on a digit to be changed, and press the appropriate number key. The cursor does
not have to be on the polarity sign of the value to change polarity. If the MENU
key is pressed, the Source Value will be clear to 0V or 0A.
4. To edit the other field, press EDIT to select it, and repeat steps 1 and 2.
5. When finished editing the source and compliance values, press ENTER or wait six sec-
onds to exit from the edit mode.
NOT E
When a compliance limit value is entered, the SourceMeter automatically goes to the
lowest (most sensitive) compliance range that will accommodate that value.
The lowest compliance levels that can be set are 0.00100pA (1fA) and 000.200mV
(200µV).
Step 3: Select measurement function and range.
Select the desired measurement function by pressing MEAS V (voltage) or MEAS I
(current).
When measuring the source (i.e., Source V Measure V), you cannot select the range using
the measurement RANGE keys. The selected source range determines the measurement range.
When not measuring the source (i.e., Source V Measure I), measurement range selection can
be done manually or automatically. When using manual ranging, use the lowest possible range
for best accuracy. In autorange, the SourceMeter automatically goes to the most sensitive range
to make the measurement.
