20 LED bar-graph voltmeter reads from 90 to 128
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  lter network
with a greatly improved capacity for stopping line
noise. This  lter incorporates a toroidal inductor and
three high-voltage capacitors to achieve a common-
mode noise attenuation of over 50 dB at 10 MHz (see
graph overleaf below).
OPTIONS
 Models PL-8 E, PL-PLUS E: “E” suf x versions
are for use in countries with 220/240 volt AC
lines. Each has ten rear panel outlets, using
internationally- accepted IEC-320 connectors.
The voltmeter on the PL-PLUS E reads from 180
to 256 VAC, in 4 volt steps.
 Models PL-PRO: 20 amp version of the PL-
PLUS with many additional high-end features.
