Measuring Insulation Resistance - Keithley Interactive SourceMeter 2450 User Manual

Section 6: Leakage current and insulation resistance

Measuring insulation resistance

The following applications demonstrate how to use the Model 2450 to measure insulator resistance.
The applications shows how to use the front-panel interface, the remote interface using the SCPI
command set, and the remote interface using the Test Script Processor (TSP
You make insulation resistance measurements between traces on a printed circuit board and
between conductors in cables and connectors.
This application sets the Model 2450 to source 20 V and makes 10 resistance readings with a 100 ms
interval time. Once the measurements are made, the output is turned off.
For this test, you will:
•
Reset the instrument
•
Set the instrument to read the rear terminals
•
Select the source voltage function and measure resistance function
•
Set the magnitude of the voltage source output
•
Turn on autoranging
•
Use the Simple Loop trigger model template to set the numbers of readings and interval time
•
Turn on the source output
•
Make readings
•
Turn off the source output
