Inline PSU Tester – User’s Guide Page 18
The main screen contains the following features and options:
Device
COM Port: The PSU Tester appears as a Virtual COM port when connected to PC.
You can determine the Virtual COM Port by opening the Device Manager and
looking for USB Serial Device (COM #) or STMicroelectronics Virtual COM Port
(COM #).
PSU Statistics
This section displays voltage, current, power, ripple and timing for each voltage rail.
A green background for a field means the value is within the acceptable range and a
red background means the value is outside the valid range. A grey background
indicates that the measurement is not yet completed, and one or two power cycles are
required for the value to be calculated. 'N/A' means that the measurement is not
available.
Overall Status
This section shows Power Status, Total Power and the status of Voltages and
Currents.
Control Buttons
Power ON/OFF: This button forces a PSU to power up/down. Do not use this button
when the tester is in inline configuration. Instead, use the “standby” button from the
computer case.
Clear Log: The monitoring software records all voltages in the system memory at
intervals set in the configuration window. This button can be used to erase all the
previous records.
Save Log: Using this button, you can save the log into comma-separated values
format (CSV) file.
Reset Min/Max: This button resets the minimum and maximum values for voltages
and currents.
Save Report: Using this button, you can save all the PSU statistics in a .txt file.
