The Transient Detector mode, permits to count the number of impulsive
interferences in the reverse band with a level higher than a threshold defined by the
user. The maximum frequency range is from 5 to 100 MHz.
In designing the PROMAX-8+, special attention was given to building a
multi-purpose, accurate, yet easy-to-use instrument. A simple keyboard gives direct
access to the various operating modes and, once in them, any measurement parameter
can be easily changed using the rotary selector/button.
In addition, it has an RS-232C terminal for connecting to a printer or computer
for producing reports on the measurements obtained.
The instrument is powered by an external rechargeable battery.
All these functions have been brought together in one instrument weighing only
half a kilo. The ergonomic, sturdy design makes the PROMAX-8 a working tool without
parallel.
