3. Safety

3.2 Intended use

This instrument is not permitted to be used in hazardous areas!

The instrument has been designed and built solely for the intended use described here, and may only be used accordingly.

The technical specifications contained in these operating instructions must be observed. Improper handling or operation of the instrument outside of its technical specifications requires the instrument to be taken out of service immediately and inspected by an authorised WIKA service engineer.

Handle electronic precision measuring instruments with the required care (protect from humidity, impacts, strong magnetic fields, static electricity and extreme temperatures, do not insert any objects into the instrument or its openings). Plugs and sockets must be protected from contamination.

The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

3.3 Improper use

WARNING! Injuries through improper use

Improper use of the instrument can lead to hazardous situations and injuries.

▶

Refrain from unauthorised modifications to the instrument.

▶

Do not use the instrument within hazardous areas.

▶

Only ever use the supplied mains cable.

Any use beyond or different to the intended use is considered as improper use.

Special hazards

DANGER! Danger of death caused by electric current

Upon contact with live parts, there is a direct danger of death.

▶

The instrument may only be installed and mounted by skilled personnel.

▶

Before replacing the fuse, cleaning, maintenance/servicing and in the event of danger, the calibrator or the micro calibration bath must be disconnected by unplugging the mains cable from the power supply outlet.

▶

The mains socket must be freely accessible at all times!

Thermal fuse

For safety, the calibrator or the micro calibration bath is fitted with an independently-operating temperature fuse, which cuts out the heater power supply if the temperature inside the enclosure is too high. Once the metal block and the liquid bath have cooled down, send in the calibrator or the micro calibration bath to WIKA for examination.

The calibrator and the micro calibration bath have been designed as measuring and control instruments. With any operation of the calibrator/ micro calibration bath not expressly provided for in these operating instructions, additional protective measures must be taken.

Since a malfunction of the calibrator/micro calibration bath can cause personal injury or damage to property, the equipment must be protected by additional electro-mechanical safeguards.

3.4 Safety instructions for using calibration liquids

Calibration liquid, water

Only use distilled water, otherwise the calibrator tank can become strongly scaled and soiled. Collect spilled liquids immediately and dispose of them properly.

11263911.05 03/2019 EN/DE/IT

3. Safety

Calibration liquid, silicone oil

WARNING! Hazardous substances silicone oils

Improper handling can result to poisoning or

personal injury.

▶

Wear the requisite protective equipment (see chapter 3.6 “Personal protective equipment”).

▶

Observe the information in the material safety data sheet for the corresponding medium.

▶

Before working with silicone oil, read the material data safety sheet. The current material safety data sheet can be found at www.wika.de on the respective product page.

▶

Only use the silicone oil included within the scope of supply or specified in these operating instructions.

▶

When working with silicone oil, sufficient ventilation should be ensured in the room since it can give off pollutants.

▶

Since silicone oil is hygroscopic, after use, always close the calibration bath using the transport cover.

▶

Before transporting with silicone oil, allow the calibrator or micro calibration bath to cool. The transport cover is fitted with a safety valve. If the micro calibration bath is closed when it is still warm, excessive pressure can build up. In order to avoid overpressuring, which could lead to damage to the liquid bath, the safety valve is activated at a pressure of approx.

2.5 bar [36 psi]. This can lead to hot vapour escaping.

WARNING! Risk of burns!

Touching the hot metal block or micro calibration bath, the hot bath liquids or the test item can lead to acute burns.

4. Design and function

4.6 Data interface

The instruments are fitted with an RS-485 communications interface. Via this interface one can connect to a PC, level converter or a network. The software protocol used is a MODBUS-RTU protocol, which is used in may monitoring programs available on the market. The transmission speed (baud rate) is factory set to 9,600 baud. Upon request, other data transmission rates are possible. The 5-pin socket has two pins, A and B, that you connect to the corresponding connections on the PC, level converter or network.

Plan view of the 5-pin panel socket

4.7 Interface protocol

The interface protocol is available on request for delivery as a specific additional document.

4.8 Protective earth monitoring

The calibrator is fitted with a protective earth monitor to keep a check on the base isolation of the heater. The monitoring unit works independently of the normal controls and switches off the heating power supply as soon as the calibrator no longer has a connection to the protective earth system of the isolation. Once reconnected to the protective earth system, the monitoring unit automatically switches the power supply back on to the heating circuit.

To connect to a PC, the RS-485 signal must be externally converted to an RS-232 or USB signal. The appropriate converter, including drivers, is available as an option. The computer records all operational data and allows programming of all calibrator configuration parameters.

The minimum requirements for operation with a USB converter are:

■

IBM compatible PC

■

Installed operating system, Microsoft® Windows® 98 SE, ME, 2000, XP (Home or Prof.) or 7

■

A USB interface (USB 1.1 or USB 2.0)

A network connection enables the connection of up to 32 calibrators/micro-baths on the same network. To connect to a network, some factory setting is required. For this, please contact the supplier or WIKA directly.

For access to the programming via the keypad while the serial interface is communicating, the message “buSy” appears on the display, and therefore indicates that it is in an “occupied” state.

5. Transport, packaging and storage

5.1 Transport

Check the calibrator or the micro calibration bath for any damage that may have been caused by transport.

Obvious damage must be reported immediately.

CAUTION! Damage through improper transport

With improper transport, a high level of damage to property can occur.

▶

When unloading packed goods upon delivery as well as during internal transport, proceed carefully and observe the symbols on the packaging.

▶

With internal transport, observe the instructions in chapter 5.2 “Packaging and storage”.

If the instrument is transported from a cold into a warm environment, the formation of condensation may result in instrument malfunction. Before putting it back into operation, wait for the instrument temperature and the room temperature to equalise.

5.2 Packaging and storage

Do not remove packaging until just before mounting. Keep the packaging as it will provide optimum protection during transport (e.g. change in installation site, sending for repair).

Permissible conditions at the place of storage:

■

Storage temperature: -10 ... +60 °C [14 ... 140 °F]

■

Humidity: 30 ... 95 % relative humidity (no condensation)

Avoid exposure to the following factors:

■

Direct sunlight or proximity to hot objects

■

Mechanical vibration, mechanical shock (putting it down hard)

■

Soot, vapour, dust and corrosive gases

■

Potentially explosive environments, flammable atmospheres

Store the calibrator or the micro calibration bath in its original packaging in a location that fulfils the conditions listed above.

6. Commissioning, operation

Personnel: Skilled personnel Protective equipment: Protective gloves and safety goggles

Only use original parts (see chapter 13 “Accessories”).

WARNING! Physical injuries and damage to property and the environment caused by hazardous media

Upon contact with hazardous media (e.g. oxygen, acetylene, flammable or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic, radioactive), and also with refrigeration plants and compressors, there is a danger of physical injuries and damage to property and the environment. Should a failure occur, aggressive media and/ or with high temperature may be present at the instrument.

▶

For these media, in addition to all standard regulations, the appropriate existing codes or regulations must also be followed.

▶

Wear the requisite protective equipment (see chapter 3.6 “Personal protective equipment”).

6.1 Operating position

The operating position of the calibrator or the micro calibration bath is in the vertical orientation, since this guarantees an optimal temperature distribution in the metal block or liquid bath.

Voltage supply

DANGER! Danger to life caused by electric current

Upon contact with live parts, there is a direct danger to life.

▶

Only ever use the supplied mains cable.

The voltage supply of the instrument is made via the power cable. This is included in the scope of delivery.

6.2 Inserts with metal block

In order to achieve the greatest possible accuracy, the use of exactly matched inserts is necessary. For this, diameter of the specimen must be accurately determined. The bore for the insert is obtained by adding +0.5 mm [+0.02 in].

Inserts

Following use, the inserts should be removed using the replacement tools and then the sleeve and block should be cleaned. This prevents the sleeves becoming jammed in the heating block.

Recommended calibration liquids for the different temperature ranges:

Water as a calibration liquid

■

Only use distilled or demineralised water, otherwise the calibrator tank can become strongly scaled and soiled.

Silicone oil as a calibration liquid

■

Only use the silicone oil recommended here.

■

When working with silicone oil, sufficient ventilation should be ensured in the room since it can give off pollutants.

■

Since silicone oil is hygroscopic, after use, always close the calibration bath using the transport cover.

Only use clean calibration liquids. The checking of temperature sensors and other temperature measuring devices may lead to the contamination of the calibration liquid. These contaminants, through the rotational movement of the magnetic stirrer, may cause an abrasive effect on the bottom tank.

Wear safety goggles!

Do not allow silicone oil to come into contact with the eyes.

6.3 Preparation of the micro calibration bath

In order to achieve the highest possible accuracy for a micro calibration bath, it should be filled with an appropriate calibration liquid.

6.3.1 Properties of the calibration liquid

Different calibration liquids, due to their specific properties, deliver varying calibration results. A compensation to the calibration liquid used in each case should, if necessary, be

■

Clean the tank

■

Before calibration, clean the sensors

■

Replace the worn magnetic stirrer

■

Replace the contaminated, cloudy calibration liquid

Wear protective gloves!

Protect hands from friction, abrasion, cuts or deep injuries and also from contact with hot surfaces and aggressive media.

6.3.2 Filling the micro calibration bath

1. Firstly, remove the transport cover.

2. Place the test item in the sensor basket.

3. Fill the tank with calibration liquid.

Following maximum filling heights are recommended:

Calibrator model max. filling height

CTB9100-165 / CTM9100-150 130 mm [5.12 in] CTB9100-165 / CTM9100-150

■

Pre-filling ex-works with the optimal height

110 mm [4.33 in]

The magnetic stirrer is a consumable.

Liquid bath

6.3.4 Insert for liquids

The insert for liquids consists of:

■

Insert with leak-proof cover

■

Sensor basket

■

Magnetic stirrer and lifter

■

Replacement tools

The transport cover is fitted with a safety valve. If the micro calibration bath is closed when it is still warm, excessive pressure can build up. In order to avoid overpressuring, which could lead to damage to the liquid bath, the safety valve is activated at a pressure of approx. 2.5 bar [36 psi]. This can lead to hot vapour escaping.

6.3.3 Operation of the magnetic stirrer

The greatest possible homogeneity is achieved by the agitation of the calibration liquid via a magnetic stirrer.

Set the stirring speed to the maximum possible. Turning the wheel upwards will increase the speed, turning it downwards slows down the stirring speed.

Front of the controller with stirrer-speed dial

Insert for liquids

WARNING! Risk of burns!

Hot liquids can lead to acute burns

▶

The insert for liquids must only be removed if the calibrator is used at room temperature.

▶

The fill level must be matched the relevant medium and the temperature.

If the insert for liquids is ordered with a new model CTB9100 micro calibration bath or a new model CTM9100 multi-function calibrator, the instrument will have been matched to the insert for liquids. Should the insert for liquids be ordered afterwards, a re-adjustment of the instrument at the customer’s will be needed.

6. Commissioning, operation

6.4 Surface insert (only CTM9100-150)

The operation of the calibrator with the surface insert is suited to a simple and the most accurate calibration possible of surface probes.

Fit the insert, which is hollow and long from the bottom, into the block using a special replacement tool. The sleeve also has three bores (1 x 3 mm, 1 x 3.1 mm and 1 x 4 mm [1 x 0.12 in, 1 x 0.12 in and 1 x 0.16 in]) directly under the surface, so that the correct surface temperature can be controlled at all times.

Following use, the inserts should be removed using the specific replacement tools and then the sleeve and block should be cleaned. This prevents the sleeves becoming jammed in the heating block.

The calibration of surface thermometers is very difficult and not fully defined. Thermometers mounted on surfaces dissipate heat from the surface and create a cold zone on the surface being measured. In the multi-function calibrators, the calibration temperature is created in a specially designed surface insert and an external reference thermometer measures the temperature directly under the surface. The reference thermometer also determines the temperature of the cold zone through integration of the temperature along the sensitive length of the reference thermometer and thus provides a true temperature calibration of surface temperature sensors.

6.5 Infrared insert (only CTM9100-150)

The operation of the calibrator with the infrared insert is suited to a quick and simple calibration of non-contact thermometers.

Fit the hollow and specially-designed insert into the block using a special replacement tool. The sleeve also has two bores in the edge (1 x 3.5 mm and 1 x 4.5 mm [1 x 0.14 in and 1 x 0.18 in]) for the accurate monitoring of the temperature.

The design and surface finish of the sleeve is important, in order that a defined emissivity of 1 is achieved.

Following use, the inserts should be removed using the specific replacement tools and then the sleeve and block should be cleaned. This prevents the sleeves becoming jammed in the heating block.

With temperatures of < 0 °C [< 32 °F] and higher air humidity, ice or dew can form in the insert. This can falsify the calibration. By capping the measurement opening, the ice or dew formation can be strongly reduced.

■

Leave the measurement opening closed as long as possible

■

Open the measurement opening for a short while for the measurement

■

Remove any ice or dew present by heating

The sleeve is designed so that the supplied external reference provides the best possible result, since the depth of the bore is adjusted to the sensitive length. If a separate external reference is used for comparison calibration, ensure that the sensitive length is known and it lies in the centre of the calibration surface.

6. Commissioning, operation

6.6 Testing of temperature sensors

To test temperature sensors, connect a separate temperature-measuring instrument to the test item. By comparing the temperature displayed on the external measuring instrument with the reference temperature, there is evidence of the status of the test item. This ensured

that the test item requires a short time until it reaches the temperature of the metal block or liquid bath.

There is no possibility for calibrating earthed thermocouples, since the heating block is earthed and this would therefore lead to false measurement results.

6.7 Start-up procedure

If the calibrator is not used for a long time, because of the materials used (magnesium oxide), moisture can penetrate the heating elements. Following transport or storage of the calibrator in moist environments, the heating elements must be taken to higher temperatures slowly.

During the drying process,it should be assumed that the calibrator has not yet reached the required insulation voltage for protection class I. The start-up set point is T [248 °F] with a holding time of T

= 15 min.

= 120 °C

anf

Once the set temperature has been reached, through short switch impulses, the radiated heating energy from the metal block or liquid bath is delivered, so that the temperature within remains constant.

Reference and set temperature display

6.10 Control of the reference temperature The red LED OUT 1 indicates that the heater is turned on.

6.8 Switching on the calibrator/micro calibration bath

1. Connect to the mains using the mains connector supplied.

2. Switch on the mains switch.

The controller will be initialised. The upper PV display will show tEst. In the lower SV display, the version number (e.g. rL 2.2) will be shown.

After approx. 5 secs, the initialisation will be complete and the calibration mode will automatically be displayed. The built-in heating or cooling elements will temper the metal block automatically from room temperature to the controller’s set temperature.

6.9 Reference and set temperature display

Upper PV display:

The red 4-digit, 7-segment display shows the current temperature of the metal block or liquid bath.

Lower SV display:

The green, 4-digit, 7-segment display shows the current set temperature of the metal block or the liquid bath.

Display with LED OUT 1

During the heating phase a steady light indicates that heating energy is being supplied. A flashing LED indicates that the reference temperature (set temperature) has almost been reached and therefore the heating energy is only being supplied in short bursts.

Control achieved via PID algorithm

To ensure good temperature stability, the cycle time of the controller is set low and the control output is usually raised.

7. Operating elements of the calibrator/micro calibration bath

There are three modes available for operation

Calibration mode

In this standard operating state the calibration of test items can be made.

Set-point mode

In this mode, the set temperature is entered.

Main menu

In this mode, all settings, such as specifying the desired temperature or setting the control parameters are made.

7.1 Selection of the operating modes for the CTM9100-150

To operate the multi-function calibrator in the desired mode of operation, first specify the correct linearisation for the controller. In the main menu (via the [P] button) select the desired function using the arrow keys.

LI Operates as a micro calibration bath DB Operates as a dry block Ir Operates as an infrared black body source SU Operates as a surface temperature calibrator

Select the liquid used depending upon the desired calibration temperature.

Dry-block operating mode

1. Cleaning the tank (if needed)

2. Inserting the insert (aluminium)

3. Set the speed of the magnetic stirrer to “0”.

4. In order to ensure the correct linearisation, set DB in the controller. For this, press the [P] button for approx. 5 secs. and confirm the appropriate setting in the main menu with [P].

5. Set the switch to the left of the controller to external reference. Connect the delivered external reference in to the socket provided and slide into the appropriate bore in the insert.

The insert has several bores into which the thermometer probes being calibrated and the external reference, for comparative calibration, can be inserted. The block is either heated or cooled to the desired calibration temperature. Once a stable temperature has been reached, the temperature probes to be calibrated can be compared with the reference thermometer.

The desired function is accepted using the [P] button. On the main screen, the desired linearisation (LI, DB, Ir or

SU) is displayed in the PV line every 5 secs.

7.2 Method of operation in calibration mode within individual operating modes

Micro calibration bath operating mode (possible with or without insert for liquids)

1. Insert the magnetic stirrer and sensor basket.

2. Fill the micro calibration bath (see chapter 6.3.2 “Filling

the micro calibration bath”).

3. Set the speed of the magnetic stirrer, in order to achieve

the best homogeneity possible.

4. In order to ensure the correct linearisation, set LI in the

controller. For this, press the [P] button for approx. 5 secs. and confirm the appropriate setting in the main menu with [P].

5. Set the switch to the left of the controller to internal

reference.

Angled thermometers, large-diameter thermometers or thermometers with special designs cannot be calibrated with a dry-well calibrator. For this reason the multi-function calibrator also has the possibility to function as a stirred liquid bath. The liquid is circulated using a magnetic stirrer and thus provides very good temperature distribution within the bath.

Infrared operating mode

1. Cleaning the tank (if needed)

2. Insert the insert (hollow, ceramic coated)

3. Set the speed of the magnetic stirrer to “0”.

4. In order to ensure the correct linearisation, set Ir in the controller. For this, press the [P] button for approx. 5 secs. and confirm the appropriate setting in the main menu with [P].

5. Set the switch to the left of the controller to external reference. Connect the delivered external reference into the socket provided and slide it into into the appropriate bore on the outer edge of the insert.

The measuring spot of the pyrometer being calibrated must be smaller than the diameter of the infrared insert.

Surface operating mode

1. Cleaning the tank (if needed)

2. Insert the insert (hollow, fitted with a collar at the top)

3. Set the speed of the magnetic stirrer to “0”.

4. In order to ensure the correct linearisation, set SU in the controller. For this, press the [P] button for approx. 5 secs. and confirm the appropriate setting in the main menu with [P].

5. Set the switch to the left of the controller to external reference. Connect the delivered external reference in to the socket provided and slide into the appropriate bore directly under the surface of the insert.

7.5.7 Recalling the stored set temperatures

The set temperature can be called up from calibration mode. Press button [U] for approx. 2 secs. The current set-point memory will be opened. On the upper PV display, the current reference temperature is indicated.

On the lower SV display, the set-point memory (SP1, SP2, SP3 or SP4) is shown for 2 secs., and then the

corresponding currently-selected set temperature is displayed.

It initially displays the set-point memory (SP1, SP2, SP3 or SP4).

Then it displays the stored set temperature.

A simple temperature profile can be generated. After switching on the calibrator or micro calibration bath, the temperature profile will run automatically.

Ramp control and temperature profile

Heating gradient, SLor

The heating gradient, SLor, is active if the reference temperature is lower than the set temperature. Each calibrator model has a maximum heating output, and thus only settings < than this heating power make sense and actually increase the time taken to achieve a set temperature.

Display on calling the set temperature

In order to retrieve a different stored set point, press button [U] again. The selected temperature value will be immediately adopted and approached.

7.5.8 Setting the ramp control and a temperature profile

Using the ramp control, the time can be defined over which the target temperature is achieved. This time may be shorter or longer than that which the calibrator or the micro calibration bath would normally require. By changing the set temperature or turning on the calibrator or micro calibration bath, it is automatically determined which of the gradients to use (heating gradient, SLor, or cooling gradient, SLoF). In the calibrator or in the micro calibration bath, the dwell time, dur.t, can be programmed so that the set temperature reached is automatically switched from the set-point memory SP1 to the set temperature in set-point memory SP2 after a predetermined time.

The heating and cooling gradients and the dwell time can be set via the parameter level, ’rEG. This is achieved by pressing button P for approx. 5 secs., this opens the main menu. The upper PV display will show OPEr. In the lower SV display, the LED SET will blink.

Operator menu OPEr

If button [P] is pressed again, this opens the groups level. The upper PV display will show OPEr. In the lower SV display, ’SP is shown and additionally LED SET will blink.

The dwell time, dur.t, is active when the set temperature, SP1, has been reached. Subsequently, the calibrator or micro

calibration bath automatically switches to set temperature SP2.

If settings have been made for these three parameters, the calibrator or the micro calibration bath will not use the new values until you either change the set temperature or until the calibrator or the micro calibration bath has been turned off and then on again. Another approach would be to switch the automatic control off before the parameter change (see chapter 7.5.2 “Switching off automatic control”), and then turning it back on (see chapter 7.5.3 “Switching on automatic control”).

7.5.8.1 Setting the heating gradient

The heating gradient, SLor, is active if the reference temperature is lower than the set temperature. The setting range stretches from 99.99 °C/min to 0.00 °C/min [99.99 °F/min to 0.00 °F/min].

The function is deactivated if SLor = InF (in no Function) is set.

You are at the parameter level (as described in chapter

7.5.1 “Menu structure, parameter levels”).

The upper PV display will show ‘rEG. In the lower SV display, SLor will blink.

By pressing button [▲], the heating gradient, SLor, will be increased. By pressing button [▼], the heating gradient, SLor, will be decreased.

By pressing button [▲] or [▼] the value is increased or decreased by 0.1. If the keys are held down for at least 1 sec., however, the value increases or decreases more rapidly, and after 2 secs. even faster, so that the desired value can be reached very quickly.

By pressing button [P], the newly-set heating gradient, SLor, is accepted. The display returns to the parameter level and the other parameters can be set.

If no button has been pressed for approx. 15 secs., an automatic return to one level above in calibration mode occurs.

After the setting has been made, the calibrator or the micro calibration bath will not use the new values until you either change the set temperature or the calibrator or the micro calibration bath has been turned off and then on again.

7.5.8.2 Setting the cooling gradient

The cooling gradient, SLoF, is active if the reference temperature is higher than the set temperature. The setting range stretches from 99.99 °C/min to 0.00 °C/min [99.99 °F/min to 0.00 °F/min].

The function is deactivated if SLoF = InF (in no Function) is set.
