WARNING!

Due to the fact that the temperature calibrator is a portable instrument, it is very
important to ensure that the socket has been earthen correctly when connecng
it to the electricity supply.
Carry out the mainentance and any repair operaon only with the equipment at
ambient temperature and disconnected from the electric power.

During the use of the temperature calibrator, the upper protecon grid may
overheat.
Do not touch the probe to calibrate when it is in the fluid reservoir.

Never change the configuraon parameters (3. Funcon Menu Level).
Do not operate the instrument in an excessively wet, oily, dusty or dirty
environment.
Do not connect any voltage to the input bushes (4), (5), (15).
Remove the cover before switching on and do not put it back unl the liquid has
reached ambient temperature and the temperature calibrator is turned off.

With the with silicon oil 47V5 verwenden absolutely do neverFLUID 100-NLR-Cal
exceed the maximum temperature of +130°!

This equipment adopt the following devices to protect operaon from hazard:

• Protecon fuse (3).

• Thermal fuse to protect the container in case of over-temperature.

• Ground conductor.

Follow this instrucons:

• Never put anything on the top of the temperature calibrator.

• Never put fuel objects (liquids) near the calibrator.

• If the temeprature calibraon bath is operang at high pressure, a fume hood should be used
to remove any vapours given off by the hot bath fluid.

• Never put any type of liquids unless water-glycol (50%) or silicon oil inside the reservoir.

• Use common sense any me.

Aer any extended use at a temperature below zero:

• Bring the Set Point to about 95...100°C le ng the temperature calibrator work
ll the water inside the oil has completely evaporated.
Using the temperature calibrator at a temperature below zero for a long me
with high environmental humidity needs it takes a long me to evaporate the
whole water inside the oil (mor than one hour could be necessary).
Air humidity when the oil has a low temperature condenses on oil surface in the
shape of ice crystals.
At 95...100°C the formaon of foam means that the water inside the oil has
evaporated.

3. Calibraon media

CAUTION

The temperature calibrator has been configured in the factory with the
parameters that opmize the performance of the equipment. Modificaon of
these parameters (3. Menu Funcon Level) can cause malfunconing or
breakage of the equipment with consequent risk of damage to objects or
injury to persons.

Before filling the reservoir, be aware of fundamental facts regarding the liquids that can be used!

3.1 Liquids

The and temperature calibrator is suitable in a field fromFLUID 100 FLUID 100-NLR- LR-Cal Cal
temperature from -12 up to 125° resp. to 140°C; different liquids can be put into the bath but not
many can work on the enre calibrator field.
Before using the temperature calibrator check the temperature field of the liquid to be used and
always remain under the safety limits. The upper temperature limit is condioned by vaporisaon,
smokiness, flammability and chemical deterioraon of the liquid. The inferior temperature limit is
condioned by freezing of the liquid.
The principal features of a liquid for constant-temperature baths are: the temperature field,
viscosity, specific heat, thermal conducvity, the thermal expansion, the dielectric resisvity, life
span, safety, etc.

3.1.1 Recommended temperature field

The recommended temperature field of the principal liquids which can be used with the
temperature calibrator are shown below. It depends principally on the equipment in which it is
used. Normally the temperature field of a liquid is greater than the one shown below, but out of
these values fome features of the liquid can jeopardise funconing inside the calibrator.

• Wasser-Glycol-Mixture (50%): recommended for operaon range -30...+60°C
Smokiness increases considerably above 70°C!

• Silikon oil type 47V5: recommended for operaon range -20...+125°C
Steam triggers combuson in the presence of a naked flame
above 136°C!

• Silikon oil type 47V10: recommended for operaon range -15...+140°C
Smokiness increases considerable above +130°C!

• Silikon oil type 47V20: recommended for operaon range +20...+140°C
Smokiness increases considerable above +130°C!

Straight water is not recommended because of the presence of limestone causes blockage of the
agitaon.

3.1.2 Viscosity

Viscosity is the property of fluids that indicates it‘s resistance to mixing and it depends on the type
of fluid and temperature.
The more viscous the fluid, the more difficult the mixing of the fluid and consequently the
distribuon of a uniform temperature inside the bath.
Liquids with a viscosity higher than 20 censtokes (cts) do not allow a good performance of the
bath, therefore they should be avoided in the and . OilFLUID 100 FLUID 100-NLR- LR-Cal Cal
viscosity is established at room temperature.

The value for water (at 20°C) is 1 cst.

Viscosity at room temperature silicone oil 47V5 5 cst

silicone oil 47V10 10 cst

water-glycol-mix 50% 5 cst
Remember that viscosity, especially in oils, varies considerably when the temperature changes:
this is the reason that characterises the use of oil in a well-defined field: normally the oil becomes
more viscous when the temperature drops, creang problems in mixing and uniform distribuon
of the temperature.

3.1.3 Thermal expansion

Thermal expansion indicates how liquid volume changes with variaon of the temperature. It is an
important factor especially regarding oils, which increase in volume with increase of temperature.
Read the filling instrucons and do not fill over the values indicated because thermal expansion
could cause the liquid to escape from the bath.
Silicone oils increase by about 10% with respect to their inial volume with a temperature increase
of 100°C.

3.1.4 Life span

The life span that you can expect depends on many condions: evaporaon, chemical
deterioraon, gelling, etc.
The life span of an oil becomes shorter becauer the higher the temperature the greater oxidaon
of the oil in contact with air.
To increase the life span:

• Use the most suitable oil at high temperature for the shortest me possible

• Place the appropriate cover with holes on the bath to allow passage of the probes, in order to

limit contact between the hot oil and air.
For example: connous use at 125°C, in open bath condions, of 47V5 silicone oil cause
deterioraon in a few tens of hours; with the deterioraon of its condions the viscosity increases
considerably; at temperature below zero the 47V5 silicone oil becomes doughy and mixing in the
bath is impossible.

3.1.5 Bath filling

Fill the temperature calibrator with the suitable fluid depending on the field of calibraon. The
liquid we recommend is 47V5 silicone oil (resp. 47V10). Fill the bath with about 43-43 cl of oil. Do
not exceed the recommended quanty, as the thermal expansion at high temperatures could
cause the liquid to escape from the upper opening.

Using 47V5, bath performances are opmal in the field from -20° to 120°C, but with a fumes
sucon device it can be used up to 125°C, liming the running me to the highest values in order
to increase the life span, while at a low temperature the viscosity, even if high, allows good
funconing of the temperature calibrator, adjusng the magnec srrer to maximum speed.
If the liquid is oen used at high temperatures, we suggest to use the appropriate cover with holes
that allow passage of the probes and place it on the bath.
Before replacing the liquid in the calibrator with a different one, it is recommended to clean the
container with absorbent paper in order to prevent mixtures of different liquids that worsen the
operang condions and, most of all, cause the liquid to leak due to incompability of the
maximum temperature.

3.1.6 Srrer adjustment

The rotaonal speed of the magnec srrer can be adjusted using knob (6). The speed increases
with a clockwise movement. Adjustment is based on the vortex produced in the liquid: an ideal
vortext should be about 2 cm high. The rotaonal speed should be raised, at low temperatures,
when high viscosity silicone oil is used. At high temperatures reduce the rotaonal speed in order
to prevent having vortexes that are too high causing the liquid to escape.
Switch the temperature calibrator off, if the rotaon is blocked, adjust the speed controller (6) to
maximum and switch on the calibrator again. If it sll does not work, perform the maintenance
indicated in chapter 6.

3.1.7 Posioning of the probes

In order to get the best performances in the calibraon, observe the following recommendaons:

• Verify that the probe is inserted for about 140 mm, avoiding touchng the bo om.

• As for the calibraon by means of comparison with a reference sample, it is necessary to
posion the two probes, respecvely the sample one and the probe to be calibrated, at the
same lavel and as close as possible.

• To get the best accuracy and stability, put over the bath the protecons disc with holes to allow
the passage of the probes (see image below).

• The protecon disc reduces the formaon of moisture condensaon in the silicone oil at low
temperatures.

• Do not insert the probes in the center of the tank, as they
interfere with srring.

• Always verify the operang range of the probes and
thermostats before calibraon: only insert them into the
liquid if the calibraon range is compable with the
temperatures set on the temperature calibrator.
For example: inserng a probe with a range 0...50°C into
a liquid at a temperature higher than 120°C could
determine the breakage of the probe‘s sensive element.

• Avoid placing too many probes at the same me,
because the agitaon of the liquid is disturbed
resulng in large calibraon errors.

5.2 Descripon of the instrument

The and temperature calibrator consists of an aluminiumFLUID 100 FLUID 100-NLR- LR-Cal Cal
block with one hole into which the sensors to be calibrated are inserted. The capacity of the fluid
tank is 500 cm³.
The Peler defices and an electronic microcontroller checks and regulates the temperature. Liquid
srring is ensured by a magnec system. A grid, to prevent the inserted probes from stopping its
operaon protects the srrer. A speed adjustment system is supplied, to ensure the best
homogeneous condion, according to the type of used fluid.
A fan, mounted in the bo om side, generates a constant air flow that reduces the temperature of
the case.

5.2.1 Thermoregulator

The thermo regulator (7) is a PID microprocessor which can be set from -12 to +125°C (resp.
+140°C). The first display line shows the measured value while the second display line displays the
input Set Point value.
Fur further specificaons and methods of use, see chapter 9 concerning the thermoregulator.

5.2.2 Main switch

The main switch (2) is found on the front of the instrument. It is fi ed with a socket for the voltage
calble, a main switch and one fuse (2.5 A for model at 230 VAC).
Note: use only fuses F. 5 x 20 mm. All the electrical part is found below the main switch.

5.2.3 Carrying handle

The temperature calibrator is fi ed with a carrying handle.

5.2.4 Liquid container

The capacity of the container is about 500 cm³.
Follow the instrucons of chapter 3.1.5 to fill the container with the suitable calibraon liquid. The
magnec srrer inside the container makes the temperature of the liquid homogeneous in order
to have the best performance. A metallic grid protects the magnec srrer.

5.2.5 Internal reference probe

The temperature sensor used for the reading and thermoregulaon is a Pt 100 resistance
thermometer. The probe is inserted directly into the aluminium container.

5.3 Operaon

The temperature calibrator can only be used correctly if the user has a good
knowledge of its basics.

Before starng with the calibraon, follow the installaon procedures.

Before any calibraons, follow the instrucons in chapter 3, and:

• Start the calibraon only at ambient temperature. Thermal shock can break the sensive
element of the probe and cause harm to operator.

• Put the probe to check into the bath. Refer to chapter 3.1.7.

• Switch on the temperature calibrator with the main switch (2) and wait for the end of the
auto-test (self-test) procedure.

• Set the required temperature value on the display:

- Press the „arrow-up“-key to increment the Set Point value

- Press the „arrow-down“-key to decrement the Set Point value

- Press the „E“-key to confirm the input value.

• It is advisable to wait for the stabilisaon of the oven before starng any calibraon.

• Adjust the srrer with the knob (6) for the best performance. The fluid must be mixed well for
good temperature uniformity and fast controller response. Set the knob (6) in middle posion
to start.

• The display shows the temperature of the calibrator and the Set Point. When the temperature
is reached and it is stable, the display shows the symbol „÷“.

• For different calibraon point, regulate the Set Point to the new temperature and wait for the
stabilisaon (“÷“).

• The temperature indicated on the display must not be considered as a reference temperature,
but only as a general indicaon of the temperature inside the bath. We suggest to insert a
precision reference thermometer (e.g. ) or, at versiones, without own displayLRT 750 -2ILR-Cal
(e.g. ).LRT FLR-Cal
At versions, the complete measuring chain (calibrators display plus reference thermometer-2I

can be cerfied.LRT FLR-Cal

To modify the regulaon parameter or to set the ramp, see the instrucons in chapter 9.
Cooling: To reduce the oven‘s temperature, change the Set Point and wait for the natural cooling.

CAUTION!

At the end of the calibraon, do not
remove the probe if it is sll at high
temperature.
Always allow the temperature
calibrator to cool down with the probe
sll inserted in order to avoid a
thermal shock to the probe itself and
harm to operator or things.

Before transporng the calibrator
make sure, that the temperature of
the liquid is close to the ambient
temperature and the closing-cap is
well ghtened.

6. Maintenance

6.1 Periodical Maintenance

• Check once a month the level of the liquid inside the fluid container.

• Check once a month the liquid and change if it is exhausted.

• To have the instrument always efficient, it is opportune to recalibrate it periodically. The
frequency of recalibraon depends on the use of the instrument, however we suggest to
recalibrate the temperature calibrator once a year.
To recalibrate the temperature calibrator it is necessary to have a high precision standard
reference thermometer and simulator and follow the instrucons of chapter 10.

• Check once a year the calibraon date.

6.2 Connous Maintenance

• At 20...30°C the fluid level should be about 30 mm under the top edge of the container.
If the liquid level is too low, fill up the level with the same liquid (ref. chapter 3).

• If the liquid is dirty, thick or exhausted at ambient temperature, it is advisable to change it.
To change the liquid, proceed with the emptying, cleaning and filling again.

Emptying of the liquid from the container of the temperature calibrator:

To remove completely the liquid from the temperature calibrator, reduce the temperature to a
value which is close to the ambient temperature. Remove the transport cap (see picture below)
from the transport cover, replace it with the emptying cover and then empty the tube. Overturn
the temperature calibrator by making the liquid leak. Collect it inside a container having adequate
dimensions resp. volume.

The temperature calibrator has three funcon menu levels (see previous page):LR-Cal

• Level 1: Funcons for the connuous usage

• Level 2: More specific funcons and for the regulaon of the calibrator

• Level 3: Typical funcons for each calibrator instrument

9.1 Funcons of the 1. Funcon Menu Level

This funcons are to be selected by pressing the „F“-key and to be confirmed by the „E“-key.

• SP
Set Point: temperature set which the temperature calibrator has to reach following the technical
specificaons.

• SP2
Set Point 2: temperature set which the temperature calibrator reaches with the set gradient and
the ongoing launched ramp procedure.

• GRAD
Gradient (from 0.1 °C/1 min): set point variaon speed during the changes from one temperature
value to the SP2 temperature value. The set gradient must be negave for descent ramps.
NOTE: gradient values to be set must be lower than the ones stated in the technical data (max.
cooling me, max. heang me) for this temperature calibrator model.

• RAMP
Ramp procedure enabling (ON) or disabling (OFF): Select „ON“ by the arrow-keys and confirm the
choice by pressing the „E“-key. The temperature calibrator will reach the set SP2 temperature with
the set gradient, starng from the same temperature as the one with which the ramp has been
confirmed. The starng temperature does not depend on the SP Set Point temperature.
If a negave ramp is set and the gradient is le posive and/or the SP2 temperature value is
higher than the current temperature, the start of the ramp will not be accepted, an alarm will
begin to run.
When the ramp is „ON“, the display shows „Ramp:...“ followed by the Set Point value on the
second line of the display. The Set Point value will reach the speed related to the set gradient.
When the calibrator temperature reaches the SP2 set temperature, the calibrator will produce an
alarm and the ramp procedure will be automacally set „OFF“; the SP2 value will be considered as
the new Set Point and the calibrator will be steadily set at that temperature.
During the ramp process, the derivave parameter will not be considered.

• Press „F“-key, set „RAMP“ to „ON“ using the arrow-keys. Press „E“-key to confirm.
Aer pressing the „E“-key for confirming the ramp start, the calibrator will acsend with the set
slope. Of course, there will be some oscillaons at the beginning since the ramp slope will not be
suitable but they will stop in a short me and then the calibrator temperature will follow the
ramp‘s set point one.

• RES
Display reading resoluon (0.1/0.01): the values admi ed are „0.1" and „0.01" and they can be
selected by the arrow-keys.

• SW/ON
Thermostat Switch ON: it displays the temperature at which the thermostat‘s contact, connected
to the „SWITCH TEST“ bushes, is closed.

• SW/OFF
Thermostat Switch OFF: it displays the temperature at which the thermostat‘s contact, connected
to the „SWITCH TEST“ bushes, is open.
The value is reset each me the power supply fails or by pressing both arrow-keys at the same
me. The value is updated every me that the thermostat‘s contact closing is detected.

• - only for versions with measuring inputsSENSOR -2I
This parameter allows at versions of the temperature calibrators (with 2 measuring-2I LR-Cal
inputs for external reference and one test item or for two test items) the reading of connected

• P.B.
Value of the Proporonal Band expessed in percentage of the value of the end temperature of this
temperature calibrator. Proporonal band means per cent of range within which there is the
variaon of the modulaon of the heang element power.

• T.I.
Integral me value expressed in seconds. The integrang acon cancels the error between the
chosen set point and the temperature reached only ba the proporonal acon. Integral me
means the length of me necessary to the integrave acon to double up the proporonal acon.

• T.D.
Derivave me expressed in seconds. When there is a step variaon of temperatures, the
derivave acon induces a greater inial adjustment, so that the calibrator will have a greater
power than it usual has due to the proporonal and integral acon only. Since the error keeps
exisng, the derivave acon reduces the impact giving the integrave acon the task of reducing
the error.

10. Recalibraon of the temperature calibratorLR-Cal

CAUTION: This secon is applicable for authorised personnel only. Personnel must be able to
operate the calibrator and must be familiar with the menu item selecon etc. Deep knowledge
about calibraon of temperature instruments is necessary.

The temperature calibrator can have a complete or paral re-calibraon yearly or when chosen by
the user. Calibraon can be carried out using the oponal CALIBRA ED200 soware or directly on
the keyboard of the temperature calibrator.

The calibraon of the internal probe is done by adjusng the internal probe at two points of the
range, using a precision reference thermometer, such as model .LRT 750LR-Cal

Only for versions of the temperature calibrators with 2 measuring inputs:-2I LR-Cal
The calibraon of the „EXT“ and „REF“ inputs is done by adjusng the inputs of the controller at
two points of the range using a mV/ohm generator, such as models orLTC 100LR-Cal

LR-Cal LEC 200.

A calibraon of the calibrator is only possible if the calibrator is set to °C as temperature unit.

10.1 Calibraon of the internal probe:

The purpose of recalibraon is to correct the error between the temperature indicated and the
value of a precision reference thermometer.
To calibrate the interal probe of the temperature calibrator, it is necessary to have a standard
thermometer with precision greater than that of the temperature calibrator, and then to follow the
instrucons:

• Insert the probe of the precision reference thermometer in the temperature bath or in the most
suitable hole of the dry block.

• Choose two calibraon points depending on the calibrator‘s range or the field where you wish
to carry out calibraons.

• Set the first calibraon point and wait for the calibrator to be stable (see symbol ).¸

• Enter the 3. Funcon Menu Level and select „Cal_chnl=INT“. Press „E“-key to confirm.

• Press „F“-key to select „P1", press the arrow-keys to set the value read with the precision
reference thermometer and press „E“-key to confirm. Confirmaon is indicated by the symbol
„*“ which appears on the display aer about 5 seconds.

• Return to the 1. Funcon Menu Level and set the second set point. Then wait for the calibrator
to be stable (indicated by „ “ on the display).¸

• Enter the 3. Funcon Menu level and select „P2", press the arrow-keys to set the value read
with the precision reference thermometer and press „E“-key to confirm. Confirmaon is
indicated by the symbol „*“ which appears on the display aer about 5 seconds.

• Select „CAL: INT“, set „Y“ (yes) and confirm by pressing the „E“-key. The calibraon begins.
The procedure takes a few seconds, at the end of which there is a audible signal „beep“.

General characteriscs: Baud Rate: 9600 Parity: No

Data bits: 8 Stop bits: 1

The communicaon runs in half duplex way which means that the transmission and recepon of data cannot be
contemporeneously present. The regulator of the calibrator replies only aer receibing a command, it never replies
itself. The command and reply are ASCII character strings, as detailed forward. The communicaon program will be
able to convert ASCII to decimal to extract numeric values. The default adress is 1. Baud rate: 2400, 4800, 9600 and
1200 baud, the default value is 9600; the other parameters are standard and cannot be changed.

Each command string is an ASCII character succession. First is $ character, the next must indicate
the instrument adress (default = 1) and than follows the commanc (4 characters):

Possibility: RVAR (data reading)

WVAR (data wring)
The ulmate part of the string depends on type of command. The character CR (carriage return)
concludes the sequence.

Data reading

Example no. 1 (Reading of the set point / variable no. 0):
The command string is: = beginning of message$1RVAR0_<cr> $

= instrument adress1
= read variableRVAR
= number of variable to read0
= space_
= end of message (carriage return)<cr>

The responding string is: (if 110,0 is the temperature in this example).*1_110,0
The character <cr> concludes the message.

Example no. 2 (reading of the EXTernal sensor / variable no. 105):
(Note: the type of sensor must be specified first, in variable no. 25).
The command string is: $1RVAR105_<cr>
The responding string is: (if 123,4 is the temperature in this example).*1_123,4
The character <cr> concludes the message.

The response does not include the temperature unit. To read the temperature unit, use the
variable 10. Command string is .$1RVAR10_<cr>
The response string is if the temperature unit is °C,*1_0
the response string is if the temperature unit is °F.*1_1

Data wring (FLOAT variables)

For wring, the command WVAR is to be used.

Example no. 1 (wring of the set point to 132,5°C); if the temperature unit is already °C, it is
enouph to write the SET POINT.
The command string ist: = beginning of message$1WVAR0_132,4<cr> $

= instrument adress1

If the temperature unit is not °C, but e.g. °F, you first should write the variable no. 10 (units) to the
required value, see table of variables.

Data wring (INTEGER variables)

Above is shown how to write into variables of type „float“. The variables number 1, 4, 8, 10, 25 and
26 have two or more states (for example, the resoluon by tenth or hundredth of °C) and to
acvate them, it is necessary to assign to the variable number the number corresponding to that
one which should be set according to the table indicated below:

Variable No.: Ramp = OFF = ON101
Variable No.: Resoluon = 0.1°C = 0.01°C401
Variable No.: Sensor input selecon = INT = INT+EXT812

= INT+REF = INT+EXT+REF34
Variable No.: Unit (of temperature) = °C = °F = K10 0 1 2
Variable No. and Variable No. :25 26

Ext. / Ref. Sensor type = Pt 100 (4) = Tc N = Tc K01 2

= Tc J = Tc R = Tc S34 5

= Pt 100 (3) = Tc E67

Example no. 1: the variable no. 1 corresponds to the acvaon of the ramp funcon. If you want to
set it ON in order to acvate the ramp funcon, you should assign the value 0, otherwise the value
1 to the variable no. 1.
The command string is: (acvates the ramp funcon)$1WVAR1_0<cr>

Example no. 2: the variable no. 8 corresponds to the acvaon of the sensor reading which can be
connected to the bushes of the external inputs. If you want to read a thermocouple type K,
connected to the „Ref.Input“, you should set the variable no. 26 to the number, corresponding to
the sensor type which you want to read (in this example: 2 - for Tc type K) and then set the variable
no. 8 to 3 (INT+REF).
The command strings are: and$1WVAR26_0<cr> $1WVAR8_3<cr>

Do likewise for other variables.
