circumstances be stored at ambient temperatures
above 50°C (122°F) or operated at ambient
temperatures above 40°C (104°F). Doing so may cause
a hazard.
About the front panel:
•For B and C versions only, the sockets on the input
module must NEVER be connected to voltages
exceeding 30V with reference to ground.
•Thermostats must not be connected to any other
voltage sources during test.
About insertion tubes, insulation plugs, well and
sensor:
•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
carrying case after use, you must ensure that the
instrument has cooled down to a temperature
below 100°C/212°F before placing it in the carrying
case.
•Never place a hot insertion tube in the optional carrying
case.
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.
About the liquid bath (RTC-158/250 A/B/C only):
•For liquid bath ensure that the sensor is absolutely
clean and dry as a few drops of water in the well (liquid
baths) might cause a steam explosion.
•Do not pour cold fluid into a hot well – it might cause
an explosion.

•AMETEK Denmark A/S does not take any
responsibility, if the well is filled with other fluids than
those recommended.
•Liquid baths should only be operated by trained
personal.
•Heat transfer fluids must only be used in calibrators
prepared as a liquid bath. If these fluids are heated
above specified temperature they will create noxious or
toxic fumes. Proper ventilation must be used.
•To avoid hazards from treating fluids in a wrong
manner, always reduce the "Max. SET-temperature
allowed” in the CALIBRATOR SETUP MENU according
to the specifications of the fluid to be used.
If using a calibrator outside of the fluids specifications
there is a risk of fire hazards, personal Injury or chemical
release.
By reducing the "Max. SET-temperature allowed”, the
calibrator cannot be used outside this temperature
range.
Be aware of the flash point, the boilling point and other
fluid properties applicable to the usage when setting the
Max. SET-temperature. Read the MSDS (Material
Safety Data Sheet) of the liquid before use. The Max.
SET-temperature must never exceed (liquid flash point –
50°C).
•Always remove the liquid from the calibrator before
transportation.
•Product information on the fluid must be carefully
investigated before use.
•Do not handle hot fluid.
•If the oil is heated beyond the flash point, it may
constitute a fire hazard.
•Do not pour water or any other fluids into a bath filled
with hot oil, because only a few drops of water might
cause a steam explosion, if poured into above 100°C
hot oil.
•Do not under any circumstances pour water on burning
oil. It might cause a dangerous steam explosion.

Caution – Hot surface
This symbol is engraved in the grid plate.
•Do not touch the grid plate, the well or the insertion
tube when the calibrator is heating up – they may be
very hot and cause burns.
•Do not touch the lid or the spill tray when the calibrator
is heating up – they may be very hot and cause burns
(RTC-158/250 A/B/C only).
•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 RTC-156/157/158/159/187 A/B/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 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

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 liquid bath (RTC-158/250 A/B/C only):
•Be careful not to overfill the well with oil.
•Avoid getting silicone oil on the clothes. It is impossible
to wash off.
•The oil level rises several centimetres when the
temperature is rising. Please read instructions in
section 3.3.2 about oil level. To stop overflow switch off
the main power and the oil level will decrease when
cooled down.
•Carefully wipe off all silicone oil from the sensor under
test to avoid spreading of the silicone oil.
•Be careful to select the right oil for the right task. Using
other than the recommended oils might cause damage
to the calibrator or degrade the performance.
•Remove excess hot fluid with the outmost care, as it
might be very hot.
•Do not attempt to remove hot fluid with the liquid
drainage tube, as it might melt.
About the well, insertion tube and sensor:
•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.
•Do not use any alkali, acid or ionic fluids in the
aluminium well as it might be damaged.

•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 – 250°C (482°F) / 700°C (1292°F) - for a
period of minimum 30 minutes (RTC-250/700 A/B/C
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.
•The tip of the sensor should rest at the bottom of the
sensor basket for optimum results (liquid baths only).
•Be careful not to submerge the handle or wire inlet of
the sensor-under-test in the fluid, as this might damage
the sensor (liquid baths only).

3.2 Preparing the dry-block calibrator
Warning
•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 free within an area of 20
cm on all sides and 1 metre above the calibrator due to
fire hazard.
