When the ignition switch or the power source of the operation circuit is turned on, a measurement operation result obtained in switch disconnection before the switch is turned on is displayed on said display part before the specific condition is satisfied, and a measurement operation result obtained by processing various signals regarding a run which are accepted after the switch is turned on is displayed after the specific condition is satisfied.
