Product : PM300Serial Number : AY86/1525
Question : Do you guys have a service manual or verification procedure for the PM300?
Also, I have a question, your manual lists the ranges in A(pk) but not A(rms). This is causing some confusion when it comes to using the % of range specification. Any way to clarify what the ranges are in A(rms)?

Hello,
We have a calibration procedure for the PM300 which is in the user manual (Section 4, p21). The latest version is available on this website here: http://www.voltech.com/Support/Forum/tabid/151/forumid/6/threadid/1514/scope/posts/Default.aspx. We do not have any other procedures that I can send to you.
The specifications are written using the peak values for ranges rather than the RMS because the PM300 can deal with a wide range of crest factors. Even though you enter the peak value of the range into the formula, the values calculated are the allowed deviations in RMS.
Best regards,
Tim.
