Source current and make measurements
When the 2470 is sourcing current, you can make current, voltage, resistance, or power
measurements.
Using the front panel:
1. Connect the device under test (DUT) as described in Test connections (on page 4-1
).
2. Set the function for your measurement. Press FUNCTION. Under Source Current and Measure,
select the type of measurement you want to make.
3. Select the source current range. Under SOURCE I on the home screen, set the Range.
4. Set the source current level. Under SOURCE I on the home screen, select Source. Use t
he
di
splayed number pad to set the value. Select OK.
5. Set voltage limits for the source. Under SOURCE I on the home screen, set the Limit.
6. Select the measurement range. In the MEASURE area of the home screen, set the Range.
7. Turn on the output by pressing the OUTPUT ON/OFF switch. The OUTPUT indicator light
turns on.
8. Hold the TRIGGER key for three seconds to change the measurement method. Select one of t
he
following options:
 Continuous Measurement: The instrument makes continuous measurements.

key.
9. O
bserve the readings.
10. When you are finished, turn the output off by pressing the OUTPUT ON/OFF switch. T
he
OUTPUT indicator light turns off.
Source values
When you edit the source value, the source is updated immediately. This allows you to adjust the
source value while the output is on.
In certain situations, you cannot change the source value immediately. These situations include:
• While the instrument is performing a sweep
• If offset compensation is enabled (ohms measurements only)
• If the Quick Setup Ohmmeter option is enabled
