APPENDIX A
Scripts
Program 2. Capacitor Leakage Test
--[[
Cap_Leak():
This program performs capacitor leakage measurement.
Required equipment:
(1) Single-channel Keithley Series 2600 System SourceMeter instrument
(1) 1µF aluminum electrolytic capacitor
Running this script creates functions that can be used to test capacitors.
The functions created are:
1. Cap_Leak(vsrc,soak) --Default value vsrc = 40V
2. Check_Comp()
3. Calc_Val(vsrc, leaki)
4. Print_Data(leaki, leakres)
See detailed information listed in individual functions.
To run:
1) From Test Script Builder
- At the TSP> prompt in the Instrument Control Panel, type Cap_Leak()
2) From an external program
- Send the entire program text as a string using standard GPIB Write calls.
