3.1 Description
The general-purpose, intrinsically safe hand-held thermometers for demanding mobile
EN
temperature measurement, distinguished by flexibility and easy handling. Temperatures
from -200 ... +600 °C can be measured.
Low-drift measuring amplifiers ensure small measurement errors, while easy-to-use
adjustment features considerably simplify adjustments and calibrations:
■
Calibration by code for fast setting of standard probes via key data
■
Physical calibration of probe and display at one, two or three different temperatures
In this way it is possible to reduce measuring errors to a minimum and ensure a high
indication accuracy.
Intrinsically safe hand-held thermometer model CTH63I0, industrial version
Its design makes CTH63I0 especially suitable for the commissioning, maintenance and
service/calibration of temperature instruments and equipment.
Intrinsically safe hand-held thermometer model CTH65I0, precision version
Due to its high accuracy of 0.03 K in ranges from -50 ... +199.99 °C, the CTH65I0 can
also be used as a reference measuring instrument in biotechnology, pharmaceutical
and food industries. The CTH65I0 is thus ideal for all service and maintenance tasks.

For operation in non-hazardous areas, the temperature ranges specified in the specifications are valid (see chapter 9 “Specifications”). The highest permissible ambient
temperature for the measuring instrument is 40 °C.
EN
3.7.1 Connecting/replacing the temperature probe
1. Switch off the instrument for probe replacement.
2. Before switching the instrument on, connect the probe, otherwise it may not be
correctly identified by the instrument.
3. Do not apply force to plug the connector into the socket.
The digital instrument and the temperature probe are connected to each other electrically by means of a separate connection cable.
For probe replacement please pay attention to the following:
■
Do not apply force to plug the connector into the sockets.
■
To connect the temperature probe to the hand-held plug the 8-pin plug connection
according to the guiding into the connection port for temperature probes.
■
Connect the connector without crossing the threads. If the connector is positioned
correctly, it can be plugged in without any significant effort.
■
To disconnect the probe, do not pull on the cable, but rather only on the connector
sleeve.
4. Transport, packaging and storage
4.1 Transport
Check intrinsically safe hand-held thermometer 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
4.2 “Packaging and storage”.
16 WIKA operating instructions, models CTH63I0 and CTH65I0
14120692.01 04/2015 EN/DE
4. Transport, 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.
4.2 Packaging and storage
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:
■
Humidity: 35 ... 85 % relative humidity (no condensation)
■
Storage temperature: -10 ... +50 °C
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
Store the instrument in its original packaging in a location that fulfils the conditions
listed above. If the original packaging is not available, pack and store the instrument as
described below:
1. Place the instrument, along with shock-absorbent material, in the packaging.
2. If stored for a prolonged period of time (more than 30 days), place a bag containing
a desiccant inside the packaging.

DANGER!
Danger to life from explosion!
Through working in flammable atmospheres, there is a risk of explosion
which can cause death.
▶
Only carry out probe replacement in non-hazardous environments!
▶
In case of any defects, the measuring instruments must not be operated
in hazardous areas!
▶
Do not use the intrinsically safe hand-held thermometer in damaged
condition. Before using the instrument, check that there are no cracks
or missing plastic parts on the case. Pay particular attention to the
insulation of the connectors.
▶
Do not use the instrument if it is not working properly. The instrument
protection might be compromised. If in doubt, have the instrument
checked.
▶
The battery compartment must not be opened in hazardous areas!
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 with extreme temperature may be
present at the temperature probe.
▶
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 2.5 “Personal
protective equipment”).
5.1 Commissioning
Before switching on connect the temperature probe(s) to the intended female
connector of the hand-held and make sure that a fully charged 9 V battery is inserted.
The probe connection sockets are marked on the instrument case with 1 or 2
correspondingly. The USB interface is marked next to them.

5.2 Switching on/Switching off
To switch the measuring instrument on and off, press the ON/OFF key. After switching
the instrument on all segments are indicated on the display for approx. 1.5 seconds (full
segment indication). For the next approx. 1.5 seconds the instrument indicates the set
probe calibration code as well as the set measurement parameter for channel 1 (e.g.
CoFF for DIN characteristic curve and P for Pt100). After that the calibration data for
the 2nd channel are displayed.
Finally, the instrument switches automatically to the measuring mode and displays the
current measurement parameter. In the upper display line (large display) the measured
value is displayed, a bar graph is located beneath it for graphical measured value
representation. In all 2-channel instruments the 2nd channel is displayed in the lower
display line (small display).
Channel 1
Line 1: CoFF P = calibration on channel 1 per DIN, probe selection set to Pt100.
Channel 2
Line 2: CoFF P = calibration on channel 2 per DIN, probe selection set to Pt100.
EN
For all measuring instruments the measuring channels can be selected
according to the model-specific measurement parameters. For the version
with only one probe the correct measurement parameter is already set.
When using the measuring instruments with several channels and/or
different probes make sure that the correct measurement parameter is set
(see chapter 9 “Specifications”).
If no probe is connected to the measuring instrument during switching on,
“open” is indicated on the display (see chapter 8 “Faults”).
