  • Power disturbances detected on multiple channels are recorded by their time, date, magnitude, and duration in a non-volatile RAM memory. This data is then retrieved from the analyzer through its serial communications port. Connections to the PQR-2020 are made between the safety connectors on the back of the unit, and the circuit panel to be tested. The power to operate the unit comes from any standard 110v/220v AC outlet. Once plugged in, the PQR-2020 immediately begins testing the signals on the input connectors. All these powerline monitors are integrated instruments which measure, record, and report power disturbances, aiding in the analysis of power quality for AC power in medical, commercial and industrial applications.
