The switches Show Load plot A and Show Load plot B
turn the indication of the corresponding impedance
graphs ON or OFF.
The switches Show Reference A and Show Reference B
turn the indication of the corresponding reference
impedance graphs ON or OFF.

Parameters And Indications For The Continuous Monitoring Of The Load Connected
Element
Default
Range
Description
The load display indicates the quotient of measured voltage
and current (U/I).
This indication shows the actual measured load, the
progression, and the set value range. The orange needle
indicates the actual value. The bright green bar indicates
which loads have already been measured while being on-line.
A red indication signals that the value exceeded or fell short
of the set value range. The dark green area represents the
allowable value range for the load of the corresponding power
amp channel. The set HIGH THRESH respectively LOW
THRESH values define the limits for this value range. Moving
the cursor over the indication bar brings up a tool-tip context
menu showing the numerical value of the lowest, the highest,
and the actually measured load values. Clicking with the right
mouse button on the indication bar, followed by a click on
Reset, clears the previously measured load values (bright
green and red ranges disappear).
The VOLTAGE display provides continuous indication of the
corresponding power amp channel’s output voltage.
The CURRENT display provides continuous indication of the
corresponding power amp channel’s output current.
300 Ohm
0.0 Ohm...70
kOhm
HIGH THRESH sets the upper limit of the allowable
impedance range (= minimum load). Once this value is
exceeded, an OPEN fault message (line interrupt) appears in
the Amplifier Control Panel.
1.0 0hm
0.0 Ohm...70
kOhm
LOW THRESH sets the lower limit of the allowable impedance
range (= maximum load). Once this value is fallen short of, a
SHORTED fault message (line short-circuit) appears in the
Amplifier Control Panel.
