SECTION 7 - MAINTENANCE INFORMATION
Sense Line Operation
Connect the channel under test to a power supply with variable current limit, set the power supply current limit to
0mA (or <10mA) and the output voltage to 6V
Set the 41-752 channel under test to 4V output.
Set the 41-752 channel under test current sink to 50mA.
The voltage measuring DMM should indicate 4V nominal, record value.
Set the power supply current limit to 40mA. The output voltage should change by less than 20mV.
Set the power supply current limit to 65mA. The output voltage should rise by >20mV.
Reset the PSU current limit to 0mA.
Set the 41-752 channel under test current sink to 100mA.
The voltage measuring DMM should indicate 4V nominal, record value.
Set the power supply current limit to 90mA. The output voltage should change by less than 20mV.
Set the power supply current limit to 120mA. The output voltage should rise by >20mV.
Repeat for all 6 channels.
