  • Question about the difference between an ohm-meter and a megger
    A ohmeter, is designed to measure ohms actually it dosent measure ohms it calulates ohms based on an applied voltage and a measured current, (snip) Right, I understand that, if the megger reads 500 Meg, the ohmmeter should read an overload, but it didn't It read 50K or so that's the wierd part of it
  • Figuring wire length with a ohmmeter? | Information by Electrical . . .
    An ordinary ohmmeter won't do it From the ITT "Radio Engineers Handbook" the resistance of #3 Annealed copper wire at 20 C (68 F) is about 0 197 ohms per 1000n ft Thus, your resistance for 600 ft would be about 0 118 ohms To measure this you need a 4 terminal ohmmeter This you can make by connecting a known DC current of about 10 A thru the
  • Infinity readings | Information by Electrical Professionals for . . .
    Along with some less common methods, an ohmmeter can apply a fixed voltage, and measure the current The display must read the inverse of the current, making for an odd looking scale on an analog meter
  • Digital Multimeter for resistance | Information by Electrical . . .
    The ohmmeter reading are actual readings Take my 20K reading of 04 Larry says "For example, if you get a reading of 3 87 with the scale set to 20K, then the resistance is 3 87K ohms So that means my resistance would be 04 ohms, but my reading at the 200 ohm scale was 44 9 ohms No, it means 04 K ohms

    While measuring resistance: Technician A uses an ohmmeter to measure resistance of a component before disconnecting it from the circuit Technician B uses a voltmeter to measure voltage drop
  • Answered: RTD Interface Problem #2: The circuit below was . . . - bartleby
    RTD Interface Problem #2: The circuit below was briely discussed earlier in the course This is an RTD interface which means it is fundamentally an ohmmeter The block X1 develops a known current of 1mA which will then develop a voltage across the RTD (R5) The resistors R1-3 represent the resistance of the "lead" wires going out to the RTD which is typically located a long distance (100's to
  • Figuring wire length with a ohmmeter? | Page 2 | Information by . . .
    Another low-tech way that is neater and requires less space is to get a second, empty spool and set both spools up side-by-side on cable pulling stands Have an assistant wind the wire off the filled spool and onto the empty spool, while you use a measuring wheel pressed against the wire on the spool to measure its length

    6 A simple ohmmeter can be constructed from an ammeter as shown in Figure P5 6 In this design the measured resistance is given by the equation R = 10 1 1 kn If this ohmmeter is used to measure the forward resistance of a signal diode, the measurement will typically be about 100 N when R, is really closer to 1 N Explain with a current versus voltage diagram Ohmmeter 10 V + I ~1 1 ΚΩ
