Specifications - Promax 25 Manual De Instrucciones

The Acquisition function lets users create and store a number of measurement
acquisitions in memory. The measurements obtained may be checked, transferred to a
PC or printed at any time.
In the design of the PROMAX-25 special care has been taken to create a
practical, accurate, yet easy-to-use device. A simple alphanumeric keypad incorporating
soft-keys facilitates direct access to the various operating modes. Once accessed,
ambidextrous navigation and selection keys can be used to easily modify any
parameter of the measurements.
Additionally, it has an RS-232 interface for connection to a printer or computer
to generate reports on the measurements performed.
The instrument is powered by means of an internal rechargeable battery.
The integration of all of these functions in a device that weights less than 1.5 kg,
with ergonomic, robust design, make the PROMAX-25 an unbeatable fieldwork tool.
