Hello. I am using a Kikusui TOS3200 to measure touch current for a 61010-1 application.
The product is double-insulated and has accessible USB port connector shells connected to the secondary circuit reference. When using the TOS3200 in meter mode (using the two external meter leads), I obtain different results than if I measure using the faceplate 5-15R outlet and one external meter lead. For each test, I'm using the same measurement networks when attempting to correlate the results. When using the outlet, the meter lead connects to the USB shell. When in meter mode, I am connecting one lead to the USB connector shell and one lead to the power conductor of interest. Has anyone experienced this with either the TOS3200 or other leakage/touch current meters? FWIW, the manual does not indicate any special considerations are needed when using meter mode. The instrument is in good condition and went through a calibration verification in AUG2016. The currents are within "Measurement range setting Range 1," but the meter is set in auto range mode. I plan some additional experiments using defined ranges, rather than auto in the next day or so. Peter Tarver The information contained in this message may be privileged and confidential.
