GETTING TO KNOW YOUR Z-100PLUS
Your Z-100Plus is a quality, precision instrument that will give you many years of outstanding
service; take a few minutes to get to know it.
Tuning is performed when the
Tune
button is pushed on the front of the Z-100Plus and held
for one second. The tuner can be placed in bypass mode by pressing the
Tune
button momentarily.
Although a DC coax jack is supplied on the rear of the Z-100Plus, the Z-100Plus may also be
powered directly from internal AA or 9V batteries (not supplied); no separate power supply is
needed. The Z-100Plus automatically powers up at the start of a tuning cycle, and goes into an
ultra-low-power sleep mode when tuning is complete. The latching relays hold the tuned
configuration indefinitely, even when DC power is completely removed. Tuning memories are
stored in FLASH memory. The internal batteries should last for approximately one year under
normal operating circumstances; longer or shorter depending upon how frequently tuning is
performed.
The Z-100Plus has 2,000 frequency memories. When tuning on or near a previously tuned
frequency, the Z-100Plus uses “Memory Tune” to recall the previous tuning parameters in a
fraction of a second. If no memorized settings are available, the tuner runs a full tuning cycle,
storing the parameters for memory recall on subsequent tuning cycles on that frequency. In this
manner, the Z-100Plus “learns” as it is used, adapting to the bands and frequencies as it goes.
Front Panel
On the front panel there is one pushbutton and two LED indicator lights.
Tune Button:
Initiates either a memory tune or a full tune, and also toggles the tuner
between “active” and “bypass” modes.
SWR LED:
Lights steady green at the end of a tuning cycle to indicate a good match has
been found.
Tuning LED:
Lights during tuning operation will also blink error codes if a good tuning
match is not found.
