The invention relates to a voltammeter and a voltammeter control method. A selection switching module, a measurement system, a voltage conversion module, an energy storage power supply module and a controller are arranged in the voltammeter, so that the controller sends a first control instruction to the selection switching module in a measurement time period after configuring a power taking time period and a measurement time period; the selection switching module only switches on the connection between the measurement system and the measured object after the selection switching module acts, the voltage of the measured object is measured, the controller sends a second control instruction to the selection switching module within the power taking time period, the selection switching module only switches on the connection between the voltage conversion module and the measured object after the selection switching module acts, therefore, the voltage of the measured object is converted by the voltage conversion mod
