Abstract

The buttonless memory system of the present invention retrieves and stores the measurement results of a sample for the user of an electronic measurement device, particularly a portable and personal electrical measurement device, with minimal user interaction. The user simply activates the portable measurement device and waits as the buttonless memory system initially cycles through the stored measurement results. The buttonless memory system stops retrieving from memory when the measurement device detects a sample or control solution. After test measurement of the sample, the user can choose to store the measurement result by deactivating the measurement device during the time the memory display is on. If the sample is a control solution, the user can delete the measurement result from memory by waiting and deactivating the measurement device after the memory display is off. In this way, the buttonless memory system provides a simple and effective memory management scheme for measurement devices.
