2.2 Description
The general-purpose, intrinsically safe hand-held thermometers for demanding mobile
temperature measurement, distinguished by flexibility and easy handling.Temperatures
from -200 ... +600 °C (-392 ... +1,112 °F) 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.

The instruments have been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specifications contained in these operating instructions must be observed.
Improper handling or operation of the instruments outside of its technical specifications
requires the instrument to be taken out of service immediately and inspected by an
authorised WIKA service engineer.
Handle the hand-held instruments with the required care (protect from humidity, impacts,
strong magnetic fields, static electricity and extreme temperatures, do not insert
any objects into the instrument or its openings). Protect the plugs and sockets from
contamination.
The manufacturer shall not be liable for claims of any type based on operation contrary to
the intended use.
3.3 Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and injuries.
▶Refrain from unauthorised modifications to the instrument.
▶Do not use any third-party manufacturer's temperature probes.
▶Do not use the instrument with abrasive media.
▶Avoid any external forces such as impacts or pressure
▶Only use the USB interface outside the hazardous areas.

The BAT segment indicates that the battery must be replaced soon. At this point correct
measurements can be performed for approx. 2 hours.
A 9 V battery is used as voltage supply of the instrument.
To avoid false readings, replace the battery as soon as the battery indicator appears.
For information on the battery see chapter 8.2 “Battery replacement”.
If the instrument is not used for a long time, the battery should be removed.
The battery must only be used in a proper fashion and must be disposed
of properly in line with the current, national regulations.When storing the
instrument at over 50 °C (122 °F), the battery must be taken out.
4.5 Temperature probe
DANGER!
Danger to life due to loss of explosion protection!
The use of incorrect temperature probes can lead to a loss of the explosion
protection.
▶Only use the Pt100 temperature probes supplied for hazardous areas!
Different temperature probes guarantee flexibility (see chpater 10 “Specifications”).
Fig. top: immersion probe
Fig. bottom: penetration probe
At the measuring point (measuring probe), the temperatures (dependent on the
temperature class) are permitted (see chapter 3.6 “Explosive atmospheres”).
For operation in non-hazardous areas, the temperature ranges specified in the
specifications are valid (see chapter 10 “Specifications”).The highest permissible
ambient temperature for the measuring instrument is 40 °C (104 °F).

Connecting/replacing the temperature probe
1. Switch off the instrument to connect or change the temperatrue probe.
2. Before switching the instrument on, connect the temperatrue 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.
4.6 USB interface
DANGER!
Danger to life from explosion!
Through working in flammable atmospheres, there is a risk of explosion
which can cause death.
▶Using the USB interface is not allowed in hazardous areas!
The model CTH63I0 or CTH65I0 has a USB interface as standard.The serial data
transmission can be used for configuration, calibration and for the transmission of
measured values from the hand-held thermometer.

5. Transport, packaging and storage
5.1 Transport
Check the 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 5.2 “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.
5.2 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 (14 ... 122 °F)
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 use the Pt100 temperature probes supplied for hazardous areas!
▶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!
▶Only replace the batteries outside the hazardous area, see chapter
8.2 “Battery replacement”!
▶Using the USB interface is not allowed in hazardous areas!
6.1 Commissioning
Before switching the instrument on, connect the temperture probe,
otherwise it may not be correctly identified by the instrument, see chapter
4.5 “Temperature probe”.
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.
6.2 Operation
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 Pfor Pt100). After that the calibration data for the
2nd channel are displayed.

Channel 2
Line 2: CoFF P = calibration on channel 2 per DIN, probe selection set to Pt100.
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 10 “Specifications”).
If no probe is connected to the measuring instrument during switching on,
“open” is indicated on the display (see chapter 7 “Faults”).
