1. Introduction
The portable readout unit is an instrument capable to give power to the sensors and to display the data
coming from them. It is generally used when the data coming from the transducers are not required or
cannot be automatically and continuously acquired (by means of a remote acquisition unit). To speed up the
reading operations, sometimes the signals of two or more sensors are grouped in centralization panels from
which, by connecting with the portable reading control unit using the cable provided and with the simple use
of a channel selector, it is possible to display data coming from all the installed sensors.
2. Initial inspection
All the instruments have been carefully inspected, both mechanically and electrically, before they leave the
factory.
Please check if all received items correspond with the packing list, your order confirmation and if the list of
components (chapter 4.1) corresponds to the material effectively present.
In case of discrepancy, please contact Pizzi Instruments or your local Representative.
NOTE: All instruments are thoroughly checked both electrically and mechanically before leaving
the factory.
Damage during shipment
If requested at the moment of the order, all instruments can be insured prior to shipment. If you receive a
damaged shipment and shipping insurance was previously arranged you should:
Report the damage to your shipper immediately
Inform Pizzi Instruments or your local representative immediately
Keep all packaging and shipping documents

current measurement value will be displayed.
The unit of measurement is indicated at the bottom of the display.
To switch off the control unit, simply hold down the ON / OFF button for 2 seconds. In order to preserve the
battery, the PDA is equipped with the automatic switch-off function which automatically switches the
