2 in 1 meters measure average values of DC Voltage or DC Current. Any two different parameters can be measured in one case with this meter. It is housed in UL 94 V-0 approved polycarbonate case and can be mounted in Mosaic mounting (cascading).
2in1 meters measure two different ranges of frequencies in the range of 45 to 450Hz. For maximum accuracy, the essential measuring range is obtained by suppressing unwanted frequency span. The meter is housed in UL94V-0 approved polycarbonate case and can be mounted in Mosaic mounting.
