Monitor 4 / I get a good battery reading on the meter, but my Monitor 4 or Monitor 4EC will not read anything at background.

You should get about 10-20 counts per minute just from background with the Monitor 4. This means that you should get 10-20 flashes of the LED, or flash and beep if it's in audio mode. If you are getting a good battery and nothing when you put it up to a source, it could be a bad tube.

Monitor 4 / What is the most sensitive setting on the Monitor 4/4EC? I see 3 settings , X1, X10 and X100.

The X1 position is the most sensitive. Typical survey should begin in the X1 position. If the needle pegs to the top of the scale, then switch the unit into X10 position. This should back the needle down, at which point the readings on the scale are the reading X 10. If the needle is still pegged to the top of the scale in the X10 position, then move the switch into the X100 position. At this point, all of the readings on the meter would be the reading X 100
