4. Select the voltage level to be sourced. Select
OK
.
5. Select the maximum allowed source current. Select
OK
.
6. Select 2-wire or 4-wire sense.
7. The output turns on and the instrument begins sourcing voltage.
8. You can adjust the source and measure settings while the instrument makes measurements.
9. When finished, turn the output off by pressing the
OUTPUT ON/OFF
switch. The OUTPUT
indicator light turns off.
Using the Performance slider
Use the Performance slider to adjust for performance (resolution versus speed).
When you adjust the Performance slider, the instrument changes settings based on where you
position the slider. As you increase reading speed, you lower the amount of resolution. As you
increase resolution, you decrease the speed. These settings take effect the next time the output is
turned on and measurements are made.
The settings that the instrument adjusts include autozero, autodelay and filter settings, display digits,
and integration rate. These settings take effect the next time measurements are made.
Note that if the instrument is set to the DC voltage, DC current, digitize voltage, or digitize current
function, changing the speed may change the function from the DC voltage or DC current to the
digitize voltage or digitize current function and vice versa.
Source voltage and make measurements
When the Model 2461 is sourcing voltage, you can make current, voltage, resistance, or power
measurements.
Using the front panel:
1. Connect the device under test (DUT) as described in
(on page 2-83).
2. Set the function for your measurement. Press
FUNCTION
. Under Source Voltage and Measure,
select the type of measurement you want to make.
3. Select the source voltage range. Under SOURCE V on the Home screen, select the button next
to Range. Select the appropriate setting.
4. Set the source voltage. Under SOURCE V on the Home screen, select the number next to
Source. Use the displayed number pad to set the value. Select
OK
.
5. Set current limits for the source. Under SOURCE V on the Home screen, select the number next
to Limit. Set an appropriate value.
6. Select the measurement range. In the MEASURE area of the Home screen, select the button
next to Range and choose an appropriate 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 the
following options:
Continuous Measurement:
The instrument makes continuous measurements.
Manual Trigger Mode:
The instrument makes measurements when you press the TRIGGER
key.
9. Observe the readings.
10. You can adjust the settings while the instrument makes measurements.
11. When you are finished, turn the output off by pressing the
OUTPUT ON/OFF
switch. The
OUTPUT indicator light turns off.
