transmitting a radio wave toward a measurement site of the user to measure pulse waves in a radial artery of a human wrist, the measurement site being a radial artery of the human wrist;

receiving a reflected wave of the radio wave reflected by the measurement site and outputting a waveform signal of the reflected wave to measure pulse waves in the radial artery of the human wrist;

extracting information indicative of a feature of a waveform from the waveform signal;

determining whether a setting position of the biological information measurement apparatus with respect to the measurement site satisfies a condition corresponding to a preset reference position based on the extracted information indicative of the feature of the waveform;

outputting information indicative of a determination result determined by the determining; and

controlling a series of operations of the transmitting, the receiving, the extracting, and the determining, wherein:

the transmitting and the receiving include transmitting radio waves and receiving reflected waves through a first antenna and a second antenna dispersedly arranged on a surface facing a surface of the measurement site, and

the controlling includes selecting the first antenna and causing the series of operations to be performed at a first time, and in response to determining that the setting position of the biological information measurement apparatus fails to satisfy the condition through the series of operations at the first time, selecting the second antenna and causing the series of operations to be performed at a second time.
