INTENDED PURPOSE
The MY-PT Series is a range of portable transmitters capable of transforming, by means of a
dedicated mobile application, PIV App by SENECA (*), Android mobile devices like
smartphones or tablets into data acquisition systems. These probes give the possibility of
displaying on your device PT100 temperature values in analogue or digital format, and of
sharing the data through the most common communication channels, like e-mail, SMS, etc.
These probes guarantee professional, certified and industrial measurements, both for
diagnostic purposes and for monitoring environmental parameters. The scopes for uses are in
connection with:
Machinery
Environmental chambers
Food storage and transport
Laboratories
HVAC systems
(*) the PIV App by SENECA can be downloaded free of charge from Google Play Store.
In order to download and install the application, and received future updates, access to the
Internet and a Google account are required.
ATTENTION! In order to be able to use MY Series probes
the mobile App must be installed on your Android device.
The instrument cannot be used without the App.

APP INSTALLATION
The dedicated mobile App for the use of Series MY probes can be downloaded from Google
Play Store, available in your device menu. In the Google Play Store search field enter PIV
App by SENECA. Once the App is found, proceed with its installation
APP INITIALISATION AND OPERATION
The application installed starts automatically when the connection of a probe through the
microUSB port is detected. The App immediately shows the instantaneous value detected,
both in analogue and digital format. The centre of the screen shows the function keys, while
the bottom provides a quick view of the data collected in real time in chart format.
During operation, the PIV App disables automatic screen lock, so that the measurements
can continue to be displayed for the user.
The display will only go off when the screen is manually put in stand-by mode by the user
by pressing the stand-by button. However, the App will continue its
measurement/datalogging activities. Simply take the device back out of stand-by mode to
view the measurements.
1) Type of probe; sampling session time;
operating range.
2) Flashing operation LED:
Black = detection;
Blue = detection/datalogger.
3) Analogue and digital format display(*).

APP INITIALISATION AND OPERATION
1) Toolbar:
play/pause: detection or datalogger.
reset: sampling time,
enable/disable: saves the value and
shows it as relative on the display,
both in analogue and digital format.
Capture screen: saves a screen
shot in the photo gallery, with the
option of exporting or sharing it
settings
2) MIN/AVG/MAX value panel.
Real-time chart of the detected value (*).
Using the settings button, it is possible to
read the model and the serial number of the
probe detected.
Below it is possible to configure:
Unit of measure
Datalogger enable/frequency
Measurement scale
Real time measurement log
Alarm thresholds, with and without
SMS, with warning sound and/or
vibration, recipients from address
book or direct entry
The panel of the datalogger sessions gives
the possibility of exporting the data in CSV
format for processing on spreadsheet, or
for loading on an analysis software like
Easy Log Viewer.
CSV file format:
INDEX: row index, incremental
number.
TYPE: LOG row type.
TIMESTAMP: date and time of the
measurement (time and device
language settings).

APP INITIALISATION AND OPERATION
<<VALUES>>: shows the main and
accessory values depending on the
type of probe; the unit of measure is
in the column name.
ALM: this will be 1 or 0, depending on
whether at the time of sampling the
alarm was enabled or not.
The PIV App gives the possibility of saving
the value on SD card (device memory path
SENECA/PIVAPP), on a cloud storage
space provider like for example Dropbox, or
to forward it as an e-mail attachment.
When the set threshold is exceeded, a
flashing icon indicates that an alarm is
present, or that the threshold has been
exceeded. During this stage, if set to do
so, your device will send a notification
SMS to the recipients. The device will not
send any further SMS until the alarm is
"rearmed".
Touch icon 1) to scroll the alarm log.
The reset key can be used to reset/rearm
the alarm function.
(*) it is possible to change the values of the scales or the MIN/AVG/MAX values using the
settings button.
