1 Instrument description and intended use TP 38 … / TP 38 … E

1 Instrument description and intended use

The calibrator is a portable unit for service, industry and laboratory tasks. The SIKA temperature calibrators
are intended to

calibrate thermometers,
temperature switches/thermostats,
resistance thermometers and
thermal elements.

The operational safety of the supplied instruments is only guaranteed if they are operated according to their
intended use (inspection of temperature sensors). Specified limit values (see “Technical Data”) should never
be exceeded.

It is your responsibility to select the instrument which is suitable for your specific application, to connect it
correctly, to carry out tests and to maintain all the components.

Various instrument versions are manufactured. The respective type plate on the calibrator displays the version
of each device.

These operating instructions apply to the following calibrator types:

TP 38 165 (cooling and heating) -35 °C up to 165 °C (with integrated measuring instrument)
TP 38 165 E (cooling and heating) -35 °C up to 165 °C (without integrated measuring instrument)
TP 38 650 (heating) ambient temperature up to 650 °C (with integrated measuring instrument)
TP 38 650 E (heating) ambient temperature up to 650 °C (without integrated measuring instrument)

The temperature calibrator consists of a controllable metal block that is capable of heating and cooling. The
metal block features the holder for the probe. You have to enter a setpoint value via an operator panel. The
nominal and actual values of the calibrator are displayed on the screen.

During the calibration, the temperature measured by the probe is compared to that displayed by the calibrator.
Various types of probes can be calibrated.

 Thermometers/SIKA machine thermometers/bimetal thermometer/dial thermometer

These are checked by comparing the temperature measured and displayed by the probe to that
displayed by the calibrator. Thereby take note of the test instructions of the thermometer producer.

 Temperature switches/Thermostats

The probe is inserted into the metal block and connected to an external display. The switch setting or
switch point is signaled via this monitoring display. In the case of calibrators with integrated measuring
instrument, the probe can be connected directly. An automatic temperature switch test can b e
performed. Thereby take note of the test instructions of the thermometer producer.

 Resistance thermometers and thermocouples

A separate temperature measuring instrument is required for the test. These devices are checked by
comparing the temperature displayed on the external measuring instrument with the block temperature.
In the case of TP 38… calibrators with integrated measuring instrument, the probe can be connected
directly. An automatic calibration can be performed.

The calibrators TP38 165 and TP38 650 are equipped with an integrated measuring instrument at which the
test specimen can attached directly. TP 38 165 E and TP 38 650 are supplied without an integrated measuring
instrument.

2 Safety instructions TP 38 … / TP 38 … E

2 Safety instructions

Always read the operating instructions carefully prior to using the new product. Always adhere to the
instructions contained herein, especially the safety instructions; otherwise, there is a potential risk of operator
injury and damage to the calibrator and the sensors being tested.

Even though SIKA provides assistance for the use of the product through personal consultation or the
respective literature, it is the responsibility of the customer to determine the suitability of the product for the
specific application.

The temperature calibrator is a state-of-the-art device. This relates to the accuracy, functioning and the safe
operation of the calibrator. However, professional and safety conscious conduct of the operator is required to
ensure safe operation.

2.1 Qualified personnel

 The personnel entrusted with start-up, operation and maintenance of the calibrator / micro calibration

bath have to be suitably qualified; the required knowledge can be gained via training courses or
appropriate on-the-job instruction. The personnel have to be familiar with the contents of these
instructions, which have to be available to them at all times.

 The electrical connection should only be carried out by a fully qualified electrician.
 All work has to be carried out in accordance with existing national regulations on accident prevention

and safety at work and with any internal regulations of the operator, even if they are not specified in
these instructions.

 Always observe the safety information contained in these operating instructions.

2.2 Basic safety regulations

 Only operate the calibrator when it is in correct, fully functional condition.
 The calibrator is energized with hazardous voltages via a mains cable. Improper use can result in

personal injuries.

 Correct and safe operation of the calibrator demands correct transport, storage, installation and

assembly, as well as proper use and careful operation and maintenance.

 The calibrator should only be used for its intended purpose. Furthermore, hazardous media should not

be used and all technical specifications have to be observed.

 If faults cannot be cleared, immediately shut down the calibrator and ensure that it cannot be started up

accidentally.

 Repairs should only be carried out by the manufacturer. Tampering with or modifying the calibrator is

strictly prohibited.

 Prior to replacing the safety fuse, always de-energize the calibrator completely by disconnecting the

mains cable from the mains outlet.

 Ensure that the complete operating instructions are always available in excellent condition at the

calibrator installation site.

 Ensure that calibrator operators receive regular instruction in the various aspects of occupational health

and safety and environmental protection and have full knowledge of these operating instructions and the
safety information contained herein.

 The customer is to verify the applicability of the product on the basis of our technical details. By this

checking, hazards and risks are subrogated to the customer and our warranty expires.

2.3 Safety instructions for TP 38 … / TP 38 … E

 Remove all highly combustible media from the vicinity of the calibrator and ensure that the calibrator

cannot come into contact with easily inflammable or explosive substances.

 Make sure that the integrated fans can always deliver sufficient cooling air. Do not impair the air supply

by placing the calibrators on a soft, resilient surface.

 Connect the calibrators to a power circuit with minimum risk of a power failure, since it will no longer be

possible to supply cooling air in the case of a power failure

2 Safety instructions TP 38 … / TP 38 … E
 Make sure that the adapter inserts and probes are not contaminated with any substances (e.g. oil) that

may cause ignition or explosion during heating.

 Attention

Never fill liquids into the adapter sleeve.

 Danger of burn!

Before touching the block or the adapter insert, check the current block temperature si nce a heated
calibrator bears the imminent risk of burns.

 Never remove adaptor inserts from a heated block since heated adapter inserts bear a fire hazard.
 Never remove probes from a heated block since these bear the imminent risk of burns.
 Never leave a heated calibrator unattended.
 Always let a heated calibrator cool to below 50 °C before disconnecting it from the mains.
 Transport the calibrator only after it has completely cooled.
 Since the housing of the calibrator is made of metal, only power cables with ground wire may be used.

Operate the calibrator exclusively with the power cable provided. The power cable connector is on the
bottom of the calibrator, i.e. when using a different type of cable, the calibrator may topple over.

 If the calibrator is not used for an extended period of time, humidity may penetrate into the heating

element due to the material used (magnesium oxide).
After transporting or storing the calibrator in a humid environment, the heating elements must thus be
heated slowly when starting the calibrator. During the drying process the calibrator will not have attained
the isolation voltage required for protection class I (refer to chapter 5).

 The noise levels of all block calibrators of the TP 38… / TP 38… E series are below 70 dbA.

2.4 Ground wire monitoring (TP 38 650 and TP 38 650 E)

For checking the basic isolation of the heater, the calibrator is equipped with a ground wire monitor. The
monitoring unit operates independently of the other controller components and switche s off the po wer supply
of the heater as soon as the calibrator loses the connection to the ground wire system of the isolation. This
condition can only be noticed by the fact that the calibrator will be cooled to room temperature. Once the
connection to the ground wire system has been re-established, the monitoring un it automatically reconnects
the heating circuit to the power system (refer to chapter "Troubleshooting").
