Meter Mode - Lab.gruppen PLM series Operation Manual

9.12 Meter Mode

In METER mode, there are three possible screen displays, referred to as "Views". Pressing the METER
button scrolls through the three views in turn: Home, Module, Temperature and Input. Each of the four
views provides different information about the PLM's performance and settings.
The four views are similar in layout. The display screen is divided into eight "blocks", arranged in two
columns of four, so that each block is associated with one soft button/tricolor LED. Each block has four rows
of alphanumeric characters, either showing textual information or acting as bargraph meters.
In addition, four sets of alphanumeric characters are displayed in inverse video in the screen center between
the left and right columns. These provide confirmation of the PLM's Module/output configuration. The
letters A or B refer to the two Lake Processing modules, and the numbers 1-4 to the up to four of PLM's
power output channels. The two examples below are given as illustration of two different module configura-
tions on a four-channel PLM.
If the processor is configured as two independent 2-way crossovers, the relationship between inputs and
outputs will be indicated as shown:

crossover configuration
This indicates that output channels 1 and 2 are driven from Module A and output channels 3 and 4 from
Module B.
If the processor is configured as a single 4-way crossover, the relationship between inputs and outputs will
be indicated as shown:
