This section will list several projects which will allow you to build your own RF design test equipment. Microwave construction techniques and basic electronic skills. Soluble Salt Tester . Simple, Free, Port Forwarding Software - By PcWinTech.com. Electronic DWT – The Deadweight Tester by Fluke Calibration is light weight, easily calibrated, and easy to setup. Request a quote today! The ease of which we can download. Simple Low Resistance Tester (Milliohmmeter): 5 Steps. Before testing the unknown resistance, measure the resistance of R1. It should be close to 2. To measure the unknown resistance (R2), attach it to the milliohmmeter's test leads. Measure the voltage across R1 and R2. When measuring R2's voltage, measure it across R2 directly. Do not measure the voltage across the alligator clips because the contact resistance will add up the voltage drop and overestimate the resistance. Based on Ohm's law, we know that R1 and R2 has equal current flowing through them. Because of this, we can use V2 and the current to calculate the unknown resistance. R2 can be calculated as follows: R2=V2/(V1/R1)Where. Java Tester. Java security news. July 26, 2017: Java 8 Update 144 has been released. The security baseline remains Update 141. Computer Sound Port Shutter Tester. I have implemented a sound port shutter tester, which is described later on this page. However I am disappointed with it's. Soluble Salt Tester measures the concentration of soluble salts (salt contamination) on metal surfaces in accordance with ISO 8502-6, 8502-9. Simple Port Tester V.3.0.0V1=Voltage across R1. V2=Voltage across unknown resistor. ![]() R1=Measured value of R1 (~2. In the second picture, I used an ammeter as an example. This link has more details about the low resistance tester. Measuring- Low- Resistances.
