1. DESCRIPTION
The Penta portable digital thermometer indicates the temperature of five distinct points. Fur-
thermore, it can indicate the differential temperature of sensors S1 and S2 or the average tem-
perature of the configured sensors.
Due to its great versatility, Penta is an excellent tool for temperature measurements in various
applications, such as: split, window, central or automotive air conditioning. It is ideal for refrigera-
tion applications such as refrigerators, freezers and cold rooms. Suitable for carrying out the
refrigeration balancing of evaporators, and can also be used to measure the average tempera-
ture inside vehicles, rooms, machines, oil, water and other liquids.
Penta is designed to get the best user experience while using it. The temperature is visualized
through an LCD display with large digits and the electronic circuit is optimized for low power con-
sumption.
1.1 MAIN FEATURES
• Automatic or manual selection of sensors;
• Records of maximum and minimum temperatures during the measurement period;
• HOLD function (locking of instantaneous indications, as well as the records of
maximum and minimum temperatures);
• Offset insertion in temperature indications;
• Battery level indication;
• Damaged sensor indication or temperature out of range;
• Differential temperature indication between sensors S1 and S2;
• Average temperature indication;
• Temperature unit selection ( { or } );
• Configurable automatic shutdown.
2. IMPORTANT CAUTIONS
• Use this product only for its intended purpose and within the parameters specified in this
instruction manual.
• If the sensor temperature is outside the specified range (-50.0 to 105.0 ºC / -58.0 to
221°F) or the sensor is damaged (short or open), the indication [,Err] will appear on the
display.
• Only indications related to the defective sensor will indicate [,Err]. The other sensors
and measurements will continue to work normally.
• Do not store the device for long periods with the batteries inside.
Important: When the device is turned off, the minimum and maximum temperature
records are reset, as well as the frozen indications of the HOLD function.

Turns the instrument on/off.
Lock the instantaneous temperature indica-
tions on the display.
Visualizes the minimum (MIN) and maxi-
mum (MAX) temperatures recorded in the selec-
ted sensor.
Selects the instrument sensors. Enables/
disables automatic selection of sensors.
5. OPERATION
Press the key for two seconds to turn on the Penta. The display will indicate the tempe-
rature measured in sensor 1, with its respective indication.
To turn off the instrument, just press and hold the key
kept pressed for one second, a countdown signal for shutdown ([Off2] and [Off1]) is indi-
cated on the display. Releasing the button before completing three seconds, the shutdown will
be cancelled.
5.1 SELECTION OF SENSORS
Selection of sensors is done by simply pressing the key
tion of sensors, press and hold the key
appears.
In automatic selection mode, the temperature of each sensor is displayed for three seconds
together with the corresponding sensor icon. To deactivate automatic selection, press the key
again for three seconds until [,aut] [,Off] appears.
Selection of sensors occurs in the following order:
During the average temperature selection, the symbols of the sensors used in the calculation will
be displayed, as set in the [,sae] function. During the differential temperature display, the
temperature difference between S1 and S2 (S1 - S2) is displayed. The DIF, S1 and S2
icons will be displayed.
5.2 HOLD FUNCTION
Pressing the key , the instantaneous temperature displays are locked. When in HOLD
mode, the HOLD indication is permanently on on the display. Even while in HOLD mode,
the current instantaneous temperatures are recorded continuously. To exit this mode, press the
key again.
