    Measuring current draw by AC motor.

    Hello guys. This isn't a job, just so that you know. Just exploring. I have a couple of AC motors and I am playing with them. One of the things I want to do is measure the current draw. So I attach them to a power source and switch it on and off they go doing their thing. No problem there...

    Measuring apps.................

    so downloaded one the other day. Free in the App Store. You use your camera to scan an area and can pin point positions and the app measures between. I have yet to try it against known measurements, but looks like it could be a useful tool for measuring cable/trunking runs etc if caught...

    Measuring component readings

    I'm fixing a turntable and want to know how to test individual components on a circuit board. Can anyone advise me on what are the most important parts to test and how? I have watched a few videos and have figured I need my multimeter on diode mode, wires on pos/neg and reading should be...

    Measuring Direct Current with Fluke Multimeter?

    I've been told I need to wire the multimeter in series with the LED I'm trying to measure. I tried doing that and now the COB won't power on. I made a diagram for the wiring when I initially successfully wired up the LED so I'll post a picture of that below along with pictures of my wiring...

    Ring final circuit question

    When you do the continuity test on a ring final circuit and you have to connect L1 to N2 and vice versa, this assumes you know which L cable is the incoming or outgoing. I understand that if you connect L1 to N1 and vice versa the ohm readings rise then fall as you go round the ring circuit...

    Which Voltage Indictor

    I've been using a Martindale neon indicator for about 10 years and it needed replacing. Purchased the Fluke T100 only to find it trips 30mA RCD's. My bad. What would be a good replacement for the Martindale or should I just by another one. I do find the the retractable probes sleeves a bit of...

    Voltage derived from differnet transformer

    When i measure the voltage between L1 of 230V transformer and L1 of 450V transformer i can measure around 180V. Can i use this voltage to light up a 220V lamp? Actually i tried it but it doesnt work and dont know why. Have tried also to any other phases but no way that it lights up..Thanks for...

    confused tns reading

    guys, Im getting confused, done a ze reading L-PE and got 0.46 ohms but on on site guide says should be 0.8 ohms do i just put the reading down on EIC. Or is this o.k :confused: all zs readings are within limits

    megger 1552

    Hello all, I am after some advice, I have just bought a megger 1552 tester. I was "practicing" with it today as I am a novice when it come to inspection and testing. I found the instruction manual a bit naff. I was trying to do a Zs/earth fault loop impedance on a radial circuit and the meter...
