Range programming example
The programming example below illustrates how to control both source and measure ranges. The

•
Voltage source range: Auto
•
Current measure range: 10 mA
•
Voltage source current limit: 10 mA
-- Restore Series 2600B defaults.
smua.reset()
-- Set V source range to auto.
smua.source.autorangev = smua.AUTORANGE_ON
-- Select 10 mA measure range.
smua.measure.rangei = 10e-3
-- Set limit level to 10 mA.
smua.source.limiti = 10e-3

Digits

The display resolution of the measured reading depends on the DIGITS setting. The default display
resolution setting is 6.5 digits. The DIGITS setting selects display resolution for all measurement
functions.
The DIGITS setting has no effect on the format of readings returned by a print() command over a
remote interface. For information to adjust the format of remote interface readings, see
format.asciiprecision
The number of displayed digits does not affect accuracy or speed. Accuracy and speed are controlled
by the SPEED setting (see

Setting display resolution from the front panel

To set the display resolution, press the DIGITS key until the correct number of digits is displayed.
Available display resolutions are 4.5, 5.5, and 6.5 digits.
For Models 2602B/2604B/2612B/2614B/2634B/2636B while in dual-channel display mode, the
maximum display resolution is 4.5 digits. For these models while in dual-channel display mode,
pressing the DIGITS key has no effect other than the displaying a message advising you to change
the display to the indicated channel. It will also happen in single-channel display mode when
pressing the DIGITS key for the channel that is not being displayed.
