These Product Tours are just a structured sequence of web pages. Click the ► button to step through them.
The navigation buttons have the following functions:

◄ is the same as your browser back button
▲ takes you up a level in the hierarchy
► steps forward to the next page
The drop-lists give another way of accessing the same pages

PL and PL-P series Tour Map
PL Series DC Supplies: Precision metering
Precision Metering - clear and unambiguous "at a glance"
High accuracy, four digit, fixed-resolution meters
The New PL series uses four digit meters for
both voltage and current.
The fixed resolution ensures that there are
no sudden and confusing changes in the reading.
Some other power supplies use 3 digit
meters which autorange at 1999 counts.
Not only does this reduce resolution, but it also changes the
position of the most significant digit. When glancing at the
display this could lead to mis-reading of the value by a factor
of ten.
Improved low current control and metering
In response to the increasing use of low power circuitry, the
PL Series incorporates a low current range.
This provides metering with 0.1mA resolution and enables lower
currents to be set with more precision.
Meter averaging function
As with the original PL series, the New PL incorporates a meter
averaging function which reduces the display cycling when
working with rapidly varying load currents.
