• "Good SPL meter, but a realy poor manual." by JOHNMAIER on 9/1/2011
  Digital Sound Level Meter with USB Interface and Datalogging

  I was impressed by the meter its self, but the manual was written by someone with poor English and technical writing skills. It's going to take a lot of experimentation to figure out how to set up the additional features.
• "Accurate Readings, but what about Self-Calibration?" by hendrikxix on 4/22/2009

  Quality:

  I just received the meter and I have put it through a series of tests. Out of the box the meter seems to be very responsive and accurate. The instructions that come with the unit are really pretty poorly written and definitely translated from another language without much care. There is no mention in the directions about an internal oscillator or self-calibration. The section on calibration talks about using an external calibrator that is not included (sells for $250). My main reason for purchasing was the claim of self-calibration. The manual recommends yearly calibration. It does include a jeweler screwdriver to perform the calibration. The box is pretty nice and feature set seems excellent. I haven't tried the software yet. There appears to be no online information for the SPL meter other than what is available at MCM Electronics. The microphone connection to the unit is a little loose, but well secured. You wouldn't want to shake the meter anyway.
