Query: Defective New Meter

Upon turning on the unit for the first time, I was surprised to hear a loud, high-pitched oscillation emanating from the meter. Ignoring the oscillation, I proceeded to test the various functions of the meter. I tried to measure a number of resistors without success. I then attempted to measure voltages, again without success. The meter was obviously defective, so I decided to return the item to Amazon. I was most pleasantly surprised by the ease of returning the defective meter. I found the return process to be a quick, simple, straight-forward procedure.
