                Comments about RadioShack® True-RMS Digital Clamp-on Multimeter:

                As a Marine Surveyor, important for me to measure AC amps in each of three legs (yes, also ground-wire) coming into boats from shorepower-connection. If unbalanced (and/or net of all three not =zero) can be stray-current leakage, lethal to swimmers nearby! This clamp-on meter would not (from day one!) accurately measure AC amps against known amp-values in 2-12amp range, confirmed by in-line meter, nor was any amps reading stable; fluctuated wildly. We're not dealing with tiny values below thresh-hold of expected meter performance here... Equivalent new meter off-shelf exhibited SAME un-reliable behavior; Must assume design is deficient. Thus, meter returned for refund.

                      Comments about RadioShack® True-RMS Digital Clamp-on Multimeter:

                      This is a nice meter, if and only if it would read correct.
                      As a True-RMS meter, it's readings should be about .707 times the full sine wave peak, as opposed to an average meter reading .673 times the full sine wave peak.

                      This meter reads approximately 10% lower than (3) average meters (Fluke, Amprobe and Field Piece), on voltage AC and amperes AC. It reads even lower compared to other True-RMS meters. The temperature reading is off by about 5 degrees (a result of a voltage DC reading problem).

                      The hz and capacitor reads correct though.

                            The DC current zero worked a few days ago. But it is now useless. I already have a pile of meters that measure just about everything, except Amps. Oh, I guess I still do.

                                    Comments about RadioShack® True-RMS Digital Clamp-on Multimeter:

                                    I bought this for the ability to measure DC current in the 4A-40A range. It doesn't work.

                                    When measuring a wire with no current, it reads between 7A and 9.5A. All measurements are off by roughly that amount.

                                    The meter cannot be zeroed! There is a button marked "zero", but when you press it the display goes to zero and the word "ZERO" appears on the LCD. Unfortunately in this mode, ALL readings are zero -- even wires with currrent! Pressing the "zero" button again turns this mode off, but it goes right back to reading high by about 7-9.5A. In other words, switching into "zero" mode and back doesn't do anything.

                                    I think there's a serious bug in the meter design -- it can't be zeroed -- and Radio Shack just won't fix it.
