 The calibrator must not be used for any purposes other than those described in

this manual, as it might cause a hazard.

 The calibrator has been designed for indoor use only and is not to be used in

wet locations.

 The calibrator is not to be used in hazardous areas, where vapour or gas leaks,

etc. may constitute a danger of explosion.

 The calibrator is not designed for operation in altitudes above 2000 meters.

 The calibrator is a CLASS I product and must be connected to a mains outlet with

a protective earth connection. Ensure the ground connection of the calibrator is properly connected to the protective earth before switching on the calibrator. Always use a mains power cable with a mains plug that connects to the protective earth.

 To ensure the connection to protective earth any extension cord used must also

have a protective earth conductor.

 Only use a mains power cord with a current rating as specified by the calibrator

and which is approved for the voltage and plug configuration in your area.

 Before switching on the calibrator make sure that it is set to the voltage of the

mains electricity supply.

 Always position the calibrator to enable easy and quick disconnection of the

power source (mains inlet socket).

 The calibrator must be kept clear within an area of 20 cm on all sides and 1 metre

above the calibrator due to fire hazard.

 Never use heat transfer fluids such as silicone, oil, paste, etc. in the dry-block

calibrators. These fluids may penetrate the calibrator and cause electrical hazard, damage or create poisonous fumes.

 The calibrator must be switched off before any attempt to service the instrument

is made. There are no user serviceable parts inside the calibrator.

 When cleaning the well or the insertion tube, REMEMBER to wear goggles when

using compressed air!

About the frontpanel:

 The connectors, on the front panel of the calibrator, must NEVER be connected to

a voltage source.

 Thermostats connected to the switch test input must not be connected to any

other voltage source during a test.

129375 00 2016-05-18 8



About insertion tubes and insulation plugs:

 Never leave hot insertion tubes, which have been removed from the calibrator,

unsupervised – they may constitute a fire hazard or personal injury.

If you intend to store the calibrator in the aluminium carrying case after use, you

must ensure that the instrument has cooled down to a temperature below 50°C/122°F before placing it in the carrying case.

 Never place a hot insertion tube in the optional carrying case.

 Use only insulation plugs supplied by AMETEK Denmark A/S.

About the fuses:

 The fuse box must not be removed from the power control switch until the mains

cable has been disconnected.

 The two main fuses must have the specified current and voltage rating and be of

the specified type. The use of makeshift fuses and the short-circuiting of fuse holders are prohibited and may cause a hazard.

Caution – Hot surface

This symbol is visible on the grid plate.

Do not touch the grid plate, the well or the insertion tube as the calibrator is

heating up – they may be very hot and cause burns.

Do not touch the tip of the sensor when it is removed from the insertion tube/well

– it may be very hot and cause burns.

Do not touch the handle of the calibrator during use – it may be very hot and

cause burns.

Over 50°C/122°F

If the calibrator has been heated up to temperatures above 50°C/122°F, you must

wait until the instrument reaches a temperature below 50°C/122°F before you

switch it off.

Do not remove the insert from the calibrator before the insert has cooled down to

less than 50°C/122°F.

Caution – Cold surface

Below 0°C/32°F (applies only to the CTC-155 C models)

Do not touch the well or insertion tube when these are below 0°C/32°F - they

might create frostbite.

If the calibrator has reached a temperature below 0°C/32°F, ice crystals may form

on the insertion tube and the well. This, in turn, may cause the material surfaces to oxidize To prevent this from happening the insertion tube and the well must be dried. This is done by heating up the calibrator to 100°C/212°F until all water left has evaporated. Remove the insulation plug while heating up.

It is very important that humidity in the well and insertion tube is removed to prevent corrosion and frost expansion damages.

129375 00 2016-05-18 9

Caution…

About the use:

Do not use the instrument if the internal fan is out of order. Before cleaning the calibrator, you must switch it off, allow it to cool down and

remove all cables.

bout the well, insertion tube and grid plate: The well and the insertion tube must be clean and dry before use. Do not pour any form of liquids into the well. It might damage the well or cause

a hazard.

Scratches and other damage to the insertion tubes should be avoided by storing

the insertion tubes carefully when not in use.

The insertion tube must never be forced into the well. The well could be

damaged as a result, and the insertion tube may get stuck.

Before using new insertion tubes for the calibration, the insertion tubes must be

heated up to maximum temperature 350°C(662°F) / 660°C (1220°F) for a period of minimum 30 minutes (CTC-350/660 only).

The insertion tube must always be removed from the calibrator after use.

The humidity in the air may cause corrosion oxidation on the insertion tube inside the instrument. There is a risk that the insertion tube may get stuck if this is allowed to happen.

If the calibrator is to be transported, the insertion tube must be removed from

the well to avoid damage to the instrument.

Note…

The product liability only applies if the instrument is subject to a manufacturing

defect. This liability becomes void if the user fails to follow the instructions set out in this manual or uses unauthorised spare parts.

3.2 Choosing an insertion tube

Caution…

To get the best results out of your calibrator, the insertion tube dimensions, tolerance

129375 00 2016-05-18 12

and material are critical. We highly advise using the JOFRA insertion tubes, as they

guarantee trouble free operation. Use of other insertion tubes may reduce

performance of the calibrator and cause the insertion tube to get stuck.

Caution…

Before using new insertion tubes for the calibration in the CTC-350/660 instruments

the insertion tubes must be heated up to maximum temperature 350°C(662°F) /

660°C (1220°F) for a period of minimum 30 minutes.

Insertion tubes are selected on the basis of the diameter of the sensor to be calibrated.

Use the table for insertion tubes in section 3.2.1 to find the correct parts number.

Alternatively, you may order an undrilled insertion tube and drill the required hole yourself. The finished dimension should be as follows:

 Sensor diameter ød+0.2 +0.05 / -0.00 mm.

 Reference sensor hole ø4.2mm +0.05 / -0.00 mm

1. Press one of the (Arrow) keys and the (Enter) key to access the Mode

menu.

129375 00 2016-05-18 23

You can choose between one of the following sensor constellations:

 Internal reference source (A and C models)  External reference source (C models only)  SET follows TRUE (C-models only)

Internal reference source

The internal reference sensor will be displayed as the TRUE value on the main screen.

The calibrator has a set of internal stability criteria it shall meet before stability is indicated. The stability time may be set beyond the internal stability criteria.

The stability time can be set (in minutes) using integers from 5 – 99

External reference source (C-models only)

The TRUE value on the main screen will be read from the Intelligent Reference Sensor connected to the REF. INPUT on the front panel (see section 4.3, fig 3). The calibrator automatically reads the calibration data and serial number of the Sensor.

SET follows TRUE (C-models only)

This function enables you to reach the TRUE temperature measured by the External reference sensor.

129375 00 2016-05-18 24

Note…

that when “SET follow true” is selected, the calibrator will control the temperature to the TRUE temperature. This means that it could take longer time before the calibrator indicates stability.

5.4 Stability setting

True: Internal reference

When internal reference is selected the calibrator uses a set of minimum internal stability criteria that shall be met before stability is indicated.

The stability time can be adjusted from the minimum internal stability time (typical 5 min) up to 99 min.

True: External reference

When internal reference is selected the user can adjust both stability tolerance and stability time.

The Stability tolerance can be set between 0.01°C to 1.00°C. The tolerance should be set low enough to utilize the good temperature stability of the calibrator –

however a low value also gives a longer time to be stable.

The stability time can be set from 1 – 99 minutes.

When the TRUE temperature has reached the specified Stability tolerance during the specified Stability time, then the stability indicator in the main screen will turn green.

5.5 Selecting the set-temperature Note…

5.7.2 The calibrator's Switch Test procedure

1) Once the Switch Test is started, the calibrator starts working towards T1 as quickly as possible. The calibrator's temperature changes (heating or cooling) and switch status are shown in the display.

2) When T1 is achieved and the temperature is stable, the text and the graphic in the bottom of the screen will change accordingly.

3) The calibrator now starts working towards T2 at the specified Rate.

4) In a normal situation, the thermostat changes state before T2 is achieved. If T2 is achieved and the temperature is stable, no results will be displayed.

5) When dead band is not selected (single temperature change) (the graphic indicates the choice), the finished switch test result is displayed.

When dead band is selected (two switch changes), the calibrator starts working towards T1 at the specified Rate.

6) Normally, the thermostat changes state before T1 is achieved. If T1 is reached and the temperature is stable, no results will be displayed.

7) The finished switch test results are displayed in the results list by pressing (F3). The results show the temperature when the thermostat has closed and the temperature when it has opened – whichever comes first. The difference between these 2 temperatures is calculated as the dead band.

6.0 Storing and transporting the calibrator

Warning

Caution…

The following guidelines should always be observed when storing and transporting the calibrator. This will ensure that the instrument and the sensor remain in good working order.

The calibrator must be switched off before any attempt to service the instrument is

made. There are no user serviceable parts inside the calibrator.

The following routine must be observed before the insertion tube is removed and the

instrument switched off:

Over 50°C/122°F

If the calibrator has been heated up to temperatures above 50°C/122°F, you must

wait until the instrument reaches a temperature below 50°C/122°F before you

switch it off.

Below 0°C/32°F (applies only to the CTC-155 models)

 Do not touch the well or insertion tube when these are below 0°C/32°F - they

might create frostbite.

 If the calibrator has reached a temperature below 0°C/32°F, ice crystals may

form on the insertion tube and on the well. This, in turn, may cause the material surfaces to oxidize.

To prevent this from happening, the insertion tube and the well must be dried.

This is done by heating up the calibrator to min. 100°C/212°F until all water left has evaporated.

Remove the insulation plug while heating up.

It is very important that humidity in the well and insertion tube is removed to

prevent corrosion and frost expansion damages.

1. Switch off the calibrator using the power control switch.

Note that the calibration procedure may be interrupted at any time using the power

control switch. Switching off the calibrator during the calibration process will not damage either the instrument or the sensor.

2. Remove the insertion tube from the calibrator using the tool for insertion tube

supplied with the instrument as shown in fig. 5.

129375 00 2016-05-18 35

Caution…

 The insertion tube must always be removed from the calibrator after use.

The humidity in the air may cause corrosion oxidation on the insertion tube inside the instrument. There is a risk that the insertion tube may get stuck if this is allowed to happen.

 If the calibrator is to be transported long distances, the insertion tube must be

removed from the well to avoid damage to the instrument.

Warning

 Never leave hot insertion tubes which have been removed from the calibrator

unsupervised – they may constitute a fire hazard or personal injury.

If you intend to store the calibrator in the optional aluminium carrying case after use,

you must ensure that the instrument has cooled to a temperature below 50°C/122°F

before placing it in the carrying case.

 Never place a hot insertion tube in the optional carrying case.  Do not touch the well or insertion tube when these are deep frozen – they might

create frostbite.

9.3 Cleaning

Caution…

 Before cleaning the calibrator, you must switch it off, allow it to cool down and

remove all cables.

 The insertion tube must always be removed from the calibrator after use.

The humidity in the air may cause corrosion oxidation on the insertion tube inside

the instrument. There is a risk that the insertion tube may get stuck if this is allowed to happen.

Caution – Hot surface

Do not remove the insert from the calibrator before the insert has cooled down to

less than 50°C/122°F

Warning (all versions)

 Never leave hot insertion tubes that have been removed from the calibrator

unsupervised – they may constitute a fire hazard or personal injury.

If you intend to store the calibrator in the optional aluminium carrying case after use,

you must ensure that the instrument has cooled to a temperature below 50°C/122°F

before placing it in the carrying case.

 Do not touch the well or insertion tube when these are deep frozen – they can

create frostbite.

Users should/must carry out the following cleaning procedures as and when required:

 The exterior of the instrument – Clean using water or isopropyl alcohol and a soft cloth.

The cloth should be wrung out hard to avoid any water penetrating the calibrator and

causing damage.

The keyboard may be cleaned using isopropyl alcohol when heavily soiled.

 The insertion tube - Must always be clean and should be regularly wiped using a soft, lint-

free, dry cloth.

You must ensure there are no textile fibres on the insertion tube when it is inserted in the

well. The fibres may adhere to the well and damage it.

If the calibrator has reached a temperature below 0°C/32°F, ice crystals may form on the

insertion tube. This, in turn, may cause the material surfaces to oxidize (CTC-155 only).

To prevent this from happening, the insertion tube must be dried. This is done by heating up

the calibrator to min. 100°C/212°F until all water left has evaporated.

Remove the insulation plug while heating up.

It is very important that humidity in the insertion tube is removed to prevent corrosion and

frost expansion damages.

 The well - Must always be clean.

Dust and textile fibres should be removed from the well using e.g. compressed air.

Warning

REMEMBER! Wear goggles when using compressed air!

If the calibrator has reached a temperature below 0°C/32°F, ice crystals may form on the

well. This, in turn, may cause the material surfaces to oxidize (CTC-155 only).

To prevent this from happening, the well must be dried. This is done by heating up the

calibrator to min. 100°C/212°F until all water left has evaporated. Remove the insulation plug while heating up.

It is very important that humidity in the well is removed to prevent corrosion and frost

expansion damages.

9.4 Adjusting and calibrating the instrument

You are advised to return the calibrator to AMETEK Denmark A/S or another accredited laboratory at least once a year for calibration.

9.5 Maintenance of STS-reference sensor

Use the configuration software CON050 supplied with the CTC to update calibration information in the intelligent reference sensor.

Read the STS- and CON050 manuals for instruction about calibration and up-/download procedure.

The following information in the sensor is used by the CTC and must be filled in correctly:

 Serial number  Model number  Sensor type  Temperature range Min/Max  Electrical output Min/Max  RTD type (CvD or ITS-90)  Calibration date  Calibration initials  Calibration period  R0, A, B and C (RTD type = CvD)  RTPW, A(LR), B(LR)C(LR)/C1(LR), C2(LR), C3(LR), C4(LR), C5(LR) A(HR), B(HR),

C(HR), D(HR) and W(HR) (RTD type = ITS-90)

All other data are not used by the CTC.
