An inexpensive, easy to build diy valve tester
valveheaven.comvariable voltage supply can be used (and was successfully in the "Sussex" valve tester design), I was looking for a simpler solution. While thinking about this a while ago, it occurred to me that the voltage multipliers that are used in my Lamington amp designs already generate several voltages

The Complete Guide to Electrical Insulation Testing
www.instrumart.comThe Megger insulation tester is essentially a high-range resistance meter (ohmmeter) with a built-in direct-current generator. This meter is of special construction with both current and voltage coils, enabling true ohms to be read directly, independent of …
TESTING FOR VOLTAGE DROP
drivcat.comVoltage Drop testing is a method of electrical diagnosis that can quickly locate high-resistance problems in a circuit. Digital Volt/Ohmmeters (DVOM's) can be used to measure the voltage drop across a load device or conductor. Voltage Drop is the loss of voltage caused by the flow of current through a resistance.
The Dielectric Voltage Withstand Test
code-authorities.ul.comThe Dielectric Voltage Withstand Test page 4 Electrical and electronic devices also exhibit current analogous to leakage current during dielectric testing. However, since the dielectric test voltage is much higher, the current will be higher as well because the capacitive charging current increases in proportion to the increased voltage.

Insert RED test lead into V˚ jack 5, and BLACK test lead into COM jack 4, and rotate function selector switch 2 to the highest V DC ( ) setting (600V). 2. Measure voltage and rotate the function selector switch to successively lower V DC ( ) settings to obtain higher resolution measurements.
