Quick Start Exceeding the specified input ranges will damage the The kit comes preprogrammed with multimeter example PCB and the components. firmware. Simply apply power to the board with a 1.5V button cell battery or with an external 1.5V voltage source. The kit can be powered by a single LR44, or similar, 1.5V button cell. The board can optionally be powered SW1 can be used to cycle through the three operational modes: voltage measurement, current measurement, and externally by a benchtop supply through J2. Maximum input voltage applied to J2 should be limited to 1.5V. frequency measurement.
