Changes over time in a measured impedance are displayed in an easy to identify manner. A measurement result display apparatus includes a processor that executes a measurement result display process that displays measurement results on a displaybased on measurement result data produced by encoding impedances that have been measured by a measurement apparatus. During the measurement result display process, the processor displays, on the displayand based on a plurality of measurement result data of impedances that satisfy a predetermined comparison condition and were produced by the measurement apparatus at different measurement times, a measurement result display screenwith measurement result displaysto(graphs) in which the impedances for respective measurement result data are aligned in order of measurement time.

Measurement apparatus and measurement result display method

A short circuit detection device for detecting a short circuit occurring in a detection target measures an electrostatic capacitance value of the detection target and determines, on the basis of the measured electrostatic capacitance value, a current value of a current to be supplied to the detection target. Furthermore, the short circuit detection device supplies the current having the determined current value to the detection target and detects a short circuit in the detection target while the current is being supplied to the detection target.

Short circuit detection device and short circuit detection method

A measuring apparatus includes: N pairs of probes that are respectively connected to a positive electrode and an external member of N rechargeable batteries that have a capacitance connected in parallel between the positive electrode and the external member; a scanner that selectively switches to one pair of probes out of the N pairs; a measuring apparatus that measures the voltage between the selected probes; and a controller. A plurality of resistance configurations to be connected between each pair of probes are provided. After a standby time has elapsed in a state where the N pairs of probes are connected to the positive electrodes and external members of the N rechargeable batteries, the controller outputs control signals to the scanner to successively switch to each pair of probes and causes the measuring apparatus to measure the voltage between the selected probes every time switching is performed.
