red respectively. The voltmeter provides three special flashing patterns to indicate abnormal conditions. (1) If only the single leftmost (beneath the 90V mark � 180V for E version) LED flashes, the input voltage is marginally low. (2) If all of the LED�s on the voltmeter flash, the input voltage is marginally high. Power to the PL-Plus�s outlets will remain unless the incoming voltage rises above the Extreme Voltage Shutdown cutoff voltage (135 - 140 volts / 270 � 280 volts E version). (3) If none of the LED�s on the voltmeter are lit, and the Extreme Voltages LED indicator is illuminated, then the PLPlus II has shut down power to its outlets because the input voltage is in a range considered extreme (in excess of 135 volts - 270 volts E- version). Digital Voltmeter: (PL-PRO D II and PM-PRO II only) Furman�s laboratory precision AC digital voltmeter continually measures incoming voltages, within a typical tolerance of +/1.5VAC. It should be noted that the voltage reading is incoming. No adjustment should be necessary on these units.

Digital Current Meter: (PM-PRO II only) Furman�s laboratory precision AC digital current meter continually measures the total circuit AC load, within a typical tolerance of +/- 0.1 amp. Because these meters feature true R.M.S. technology, the current readings are accurate regardless of load conditions (capacitive, inductive or resistive). NOTE: The PL-PRO II, PL-PRO D II, and PMPRO D II, do not compensate for high or low line voltage. If you frequently move your rack to different locations, derive power from generators, use long extension cords, travel internationally, or are in an area prone to brownouts, you may benefit from the use of one of Furman�s AC Line Voltage Regulators. On/Off Circuit Breaker: This 20 amp capacity magnetic circuit breaker switch is specifically designed to stand up to the enormous high inrush current demands of many Power Amplifiers. Additionally, the switch is shielded from accidental power disconnection with a hinged cover. (E-versions feature 16 amp
capacity)

Extreme Voltage Shutdown Indicator: This LED is normally off. It monitors a hazard common in the entertainment industry: wiring faults � for example, accidental connection to 220VAC where 120VAC is expected, or an open neutral from a 208 or 240VAC feed. The Series II SMP circuit senses voltages that are
