PURPOSE:To switch a measuring range at a low cost by deciding an input level of a measuring signal, switching a recording range thereby, and also, utilizing a microcomputer in order to execute printing of the recording range. CONSTITUTION:In accordance with a program which has been stored in a ROM 6, a CPU 1 brings a measuring signal of each channel to time division, and inputs a digital measuring signal which has been obtained through an A/D converter 8. In this case, a switching means 71 decides a level of the digital measuring signal, and switches a measuring range in accordance with a decided level. At this time, a display means 73 displays measured data on a display device. Also, the measured data on recording paper by a recorder and the recording range are printed by a printing means in a microcomputer. |
