CONTENTS

■During the installation and operation of the instrument, the

following instructions should be adhered to:

1) The instrument should be installed by a skilled person.

2) Always follow the connection diagrams closely to install the

instrument.

3) Do not power or connect the instrument if any part of it is

damaged.

4) Before touching the terminals, make sure the wires to be

connected to the instrument are not live.

5) The connection cables should be able to resist the maximum

operating temperature (Tmax), obtained from the sum of the

maximum ambient temperature (Ta) + a temperature of 20 °C

(Tmax= Ta + 20 °C)

6) The instruments guarantee main insulation between the low

voltage parts (250 V) and the very low voltage parts.

7) Any external switches connected to the control should guarantee

a minimum insulation at the operating temperature of 250 V AC

or should be protected by an equivalent insulation.

8) The instruments require no maintenance.

User Manual Digital Thermometers

English

• TM series of digital thermometers for the measurement and display of the

temperature using thermocouple or thermal resistance probes.

• Three dedicated models for probe input:

- P T CThermal resistance PTC ( ositive emperature oefficent) - Ni, Pt

model TM NiPt

- N T CThermal resistance NTC ( egative emperature oefficent)

model TM NTC

- Thermocouples TC - J, K, L, R, S, T, E, N

model TM JK

• Setting of programming probes.

• Two probe inputs for model TM -P3D - for the measurement of two NTC

temperatures that can be displayed either through the closure or opening

of an outside consensus to be connected to the instrument.

• Thermometers with led 3 digit, seven segment and decimal point

display 3 (excluding the model TM -P7A, with 4 digits and maximum JK

display of +1600 °C).

• Display range: -99 ÷ +999 °C (excluding model TM -P7A, with 4 digits andJK

display range -99 ÷ +1600 °C).

• Display resolution: 0.1 °C (-9.9 ÷ +99.9 °C)

e 1 °C (< -9.9 °C e > +99.9 °C).

• Precision: ±0.5 % of the end of scale value ±1 digit (at ambient T 23 °C).

• Sampling time: 0.5s.

• Possibility of displaying the minimum and maximum temperature.

• Possibility of varying the probe calibration offset.

• Possibility of varying the temperature measurement unit

between °C and °F.

TECHNICAL SPECIFICATIONS

• Possibility of varying the update speed for the display of the measurement.

• Possibility of entering an access password for the protection of

the settings.

• Acoustic and visual alarm warning due to probe malfunction or sensor cable

disconnected.

• Infrared receiver with RC-5 protocol (models TM NiPt - ..P3..

and TM JK - ..P3... only) for remote control (accessory available separately for

remote programming).

• Available in 33x75 mm and 72x72 mm rear panel versions.

• Power supply: see table on the following page.

• Rated power: 3 VA for the 33x75 models.

4.5 VA for the 72x72 models.

• Max absorption: 100 mA at 12 V - 50 mA at 24 V.

• Operating temperature: 0 ÷ +50 °C.

• Operating humidity: <80%.

• Storage temperature: -10 ÷ +70 °C (<80% RH).

• Protection level: front panel IP54

terminals IP20

User Manual Digital Thermometers

English

In model TM -P3D, the display of the second temperature is NTC

indicated by the led at the position of the marking T2.

Keys

• There are three parameter setting keys:

Parameter confirm and programming/display key.

Parameter increase key or movement to the next parameter.

Parameter decrease or exit menu key.

• Adhere strictly to the safety warnings and the instructions in the

connection “diagram section”.

Normal operation

• This operation is obtained outside the parameter programming mode.

In this status, the instrument takes the measurement on the basis of the

parameters set. The information displayed is as follows:
