Often simple steps during regular preventive maintenance can give you a great measure of your ultrasound equipment's performance and alert you to possible failures in advance. One quick easy tip to measure your system's performance is to log your power supply voltage. As part of any regular service call or your preventive maintenance, simply log each of your voltage measurements from the individual supply measurement points. This simple 5-minute task could allow to make power supply adjustments or recognize proactively that a power supply replacement is necessary. Below you find example pictures of two different iU22/iE33 power supply versions and a simple spreadsheet you can print out and use for each of the ultrasound units in your facility.
