Testing with an Application Development Environment
1.
Disconnect the output connector from the NI 4136/4137 front panel.
2.
Ensure that the safety interlock input on the test fixture is closed.
3.
Set the
niDCPower Output Function
property or
NIDCPOWER_OUTPUT_FUNCTION
attribute to DC Voltage for the NI 4136/4137.
4.
Set the voltage level range to 200 V, and set the voltage level to 42.4 V.
5.
Set the current limit range to 1 mA, and set the current limit to 1 mA.
6.
Initiate the session.
7.
Verify that the Voltage Status Indicator is amber.
8.
Open the safety interlock input using the test fixture.
9.
Verify that the Voltage Status Indicator is red.
10. Reset the device using the niDCPower Reset VI or the
niDCPower Reset
function.
11. Verify that the Voltage Status Indicator is green.
Caution
If the NI 4136/4137 fails the safety interlock test, discontinue use of
the device and contact an authorized NI service representative to request a
Return Material Authorization (RMA).
Testing with the NI-DCPower Soft Front Panel
1.
Disconnect the output connector from the NI 4136/4137 front panel.
2.
Ensure that the safety interlock input on the test fixture is closed.
3.
In the NI-DCPower SFP, set Output Function to DC Voltage.
4.
Set Voltage Level Range to 200 V, and set Voltage Level to 42.4 V.
5.
Set Current Limit to 1 mA, and set Current Limit Range to 1 mA.
6.
Ensure that Local sense is selected.
7.
Check the
Output Enabled
checkbox to enable the output.
8.
Verify that the Voltage Status Indicator is amber.
9.
Open the safety interlock input using the test fixture.
10. Verify that the Voltage Status Indicator is red and that a hazardous voltage error message
appears.
11. On the error message dialog, click
OK
to prompt the NI 4136/4137 to attempt to clear the
error and re-initialize the session to default values.
12. Verify that the Voltage Status Indicator is green.
Caution
If the NI 4136/4137 fails the safety interlock test, discontinue use of
the device and contact an authorized NI service representative to request a
Return Material Authorization (RMA).
