• 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.

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.

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.
About 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
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.
129375 03
2017-08-11
12
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
• When drilling the holes it is important that the distance of the material between the drillings
is at least 2mm. If the distance is less than 2 mm the calibration result could be
compromised.

Main screen temperature values
Two temperatures are always displayed:
•
TRUE temperature: This is the reference temperature of the calibrator. The TRUE
temperature can either be the internal reference or the external reference.
•
SET temperature: This is the target temperature for the well. SET temperature displays the
last value entered. If no value has been entered previously, "---,--" is displayed.
Additional temperatures displayed:
•
If External reference is selected as TRUE temperature, the temperature of the internal
reference is also displayed.
4.2.2
Stability of temperature values
The stability of the TRUE temperature is indicated by the following messages:
•
•
•
"Not stable": Indicates that the measured temperature is not yet within the specified
stability criteria.
Indicates "Time to stable": The temperature changes are within the specified stability
criteria (see section 10.0) and states a time (in minutes and seconds) when the stable
situation can be achieved.
Indicates that the “stable” situation is achieved and for how long the calibrator has
been stable. When the calibrator has been stable for more than 99 minutes, only the
stable sign is displayed (time is no longer displayed).
•
If External reference is selected as TRUE, the stability criteria will refer to this.
The criteria can be changed, however, if the temperature stability criteria is set
wider or the stability time is set shorter, the calibrator may not reach the SET
temperature.
When the instrument is heating up and cooling down indication of this will be shown as
following symbols:
•
The instrument is heating up.
•
The instrument is cooling down (CTC-155 only).
•
The instrument is cooling down (CTC-350/660 only).

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

Storing and transporting the calibrator
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.
Warning
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.

Caution…
•
•
129375 03
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.
2017-08-11
35
Warning
•
•
•
129375 03
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.

Maintenance
9.1
Replacing the main fuses
Warning
• 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 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.
Fig. 6
Replacing fuses
A. Locate the main fuses in the fuse box in the power control switch and check the
voltage of the power control switch (on/off switch (230V/115V)). If the voltage of the
power control switch differs from the line voltage, you must adjust the voltage of the
power control switch.
B. Open the lid of the fuse box using a screwdriver and remove the fuse box.
C. Replace the fuses. The fuses must be identical and should correspond to the line
voltage.
115V: 10AF/250V =

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, lintfree, 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!
