The Signal Averaging Mode (SAM)
Upon power-up, the Analyzer defaults to the instantaneous algorithm for
power output measurement, which shows fluctuating ESU output if it exists.
You can select the desired SAM by depressing the
MODE SELECT
and -
OHM SELECT
keys simultaneously. Each time you initiate this key
sequence, the Analyzer increments to the next mode. Starting at the default
mode (“F 0”), the next mode entered is the one-second signal-averaging mode
(“F 1” appears on the display). Initiating the key sequence again selects the
two-second signal averaging mode (“F 2” appears on the display). Initiating
the key sequence again brings the unit back to the default instantaneous mode
(“F 0” appears on the display), and so on.
Testing the ESU
The sections that follow describe the specific ESU tests you can perform using
the Analyzer. Test procedures prompt you to manually connect test leads in the
required configuration.

Warning
To avoid possible electric shock, burning of the skin, or
personal injury, follow these guidelines: Retractable end
of test leads are for use on ESU only. No probes or
accessories supplied with the analyzer are intended for
handheld use. Set up using the safety test leads and stand
clear when activating the ESU with the footswitch.
The Analyzer does not internally configure the test leads. You can view
functional-block diagrams for each test at the end of each test procedure
section in this chapter. Additional information about test leads is given in
“Installation.”
