Are you saying that on PQ log software line 3 is red? Is this the third phase of the measurement?

    yes the third phase

  • Brad Brown May 24, 2013

    that is the color code for that phase. It does not mean anything is wrong.

  • glenn samlal May 24, 2013

    yes but its reading 172V and the volt meter is reading 204V

  • Brad Brown May 24, 2013

    Calibration of both items not being questioned, do you have scaling set and what is the interval?

  • glenn samlal May 27, 2013

    the fluke is 172v showing red as a under-voltage but a greenlee clamp on isshowing the blue at 204V which is correct

  • Brad Brown Jun 02, 2013

    Measure something else with those probes and see if the say the same thing. That would rule out any parasitic interference that one of the probes might have and issue with or any calibration issues.

No ohms on 179 fluke meter

check input protection (thermistor (black components - first in line at Voltage terminals should be around 1kOhm, next is 2W resistor = 1kOhm and then 3 varistors (blue) open or very high ohms).

Cannot get my Fluke 36 clampmeter to read amps

1. make sure that all buttons can be pressed freely (not stuck)
2. make sure when measuring AC current that you press AC button and AC sigh is on LCD
3. make sure that jaws are closed completely
4. clamp meters use Hall effect and can only measure current flowing through ONE conductor (you cannot measure current around power cord (which has 2-3 or more conductors)
5. when in DC setting and you turn zero knob does value changes (it should)

I keep getting wrong cables message when I try to set reference with my Fluke Omniscanner. I can do a wire map but the last pairs show shorts. Could the cables be defective?

They might be defective but if they are new and originaly supplied from Fluke the chance is minimal, but it is possible. Try with another set of the cables.

The tv is showing red lines on the screen.

These are retrace lines. The screen on the red tube is turned up too high. Inside the set there are 6 knobs. 3 for focus & 3 for screen. Turn down the red screen until lines are gone. These knobs are usually found by pulling of the front panel.
