Power line disturbances are real, and they are inevitable. According to Consumer Reports (November, 1994), "One significant surge a day is the norm. High-exposure areas may experience perhaps a hundred smallish spikes a day." Proper protection is essential for costly equipment, even more so if it is frequently moved from location to location.
The PL-PLUS is an enhanced version of the PL-8, offering improved noise filtering and an AC voltmeter. The 20 LED bar-graph voltmeter reads from 180 to 256 volts in 2-volt steps. The normal range voltages are indicated in green, with moderately and extremely high or low voltages in yellow and red respectively. The voltmeter's accuracy is ±2 volts. It can easily be recalibrated if necessary. The PL-PLUS also features a longer, 10 foot heavy-duty 14 gauge power cable. In addition, it offers a sophisticated RFI filter network with a greatly improved capacity for stopping line noise. This filter incorporates two toroidal inductors and three high-voltage capacitors to achieve a common-mode noise attenuation of over 50 dB at 10 MHz.
