摘要： PURPOSE:To prevent a measuring error, by a method wherein the rotary number of an engine when the current of a battery charging system is converted to positive from negative mode and the rotary number thereof when the current is contrarily converted to negative from positive mode are calculated and the average value of these rotary numbers is employed as measuring data. CONSTITUTION:When the rotary number of an engine 1 is gradually raised, the current of an electric line 5 connected to a battery 4 is converted to a positive (charging) state from a negative (discharge) state. The converted state is carried out by detecting a current value + or -0 by a current converting and measuring means 7 through a probe 6 connected to the electric line 5. The rotary number is measured by a rotary number measuring means 8 on the basis of said detection and stored in memory 10 by a measured data gathering and recording means 9. A state wherein the rotary number of the engine 1 is gradually lowered and a current is converted to the negative state from the positive state is detected by a current converting and measuring means 7 to measure the rotary number thereof and the average value of both rotary numbers are calculated by an average value calculating means 12 through the gathering and recording means 9 to be displayed by a display means 13.
