PURPOSE:To directly read the converted value of a measured value by providing detection scales for measured values and arithmetic scales on a dial, and connecting those scales with a cursor. CONSTITUTION:On both sides on a dial 3, a curved detection scale 1 for a progressive wave, and a detection scale 2 for a reflected wave are arranged opposingly to each other, and linear arithmetic scales 4, 5 and 6 having numerals obtained by previously processing detected numerals are provided between said scales; and a center cursor 7 is rotated to connect two left and right points, thus reading a desired value directly. |
