1. Power Probe The PSP Power Probe is a three phase data logger, quality of supply monitor, and remote terminal unit for demand-side- management. Historical information of two months is kept in non volatile memory for later analysis. Communication options to the unit include direct connection to a computer or PDA serial port, dial- up modem, or real-time communication via the internet.
