1.1 Safety Instructions

This device has been designed and tested in accordance with
the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be
guaranteed unless the standard safety measures and special
safety advises given in this manual will be adhered to when
using the device.

1. Trouble-free operation and reliability of the device can only be
guaranteed if the device is not Subjected to any other climatic
conditions than those stated under "Specification".

2. Device and sensors have to be handled with care (don't throw,
hit, etc.). Protect plugs and sockets from soiling.

3. If the device is transported from a cold to a warm environment
condensation may cause in a failure of the function. In such a
case make sure the device temperature has adjusted to the
ambient temperature before trying a new start-up.

4. If device is to be connected to other devices (e.g. via serial
interface) the circuitry has to be designed most carefully. Inter­nal connection in third party devices may result in not-permis­sible voltages impairing or destroying the device or another
device connected.

If device is operated with a defective mains power supply (e.g.
short circuit from mains voltage to output voltage) this may
result in hazardous voltages at the device
(e.g. at sensor socket or interface).

GB

5. If there is a risk whatsoever involved in running it, the device
has to be switched off immediately and to be marked accor­dingly to avoid re-starting.

Operator safety may be a risk if:

■ there is visible damage to the device

■ the device is not working as specified

■ the device has been stored under unsuitable conditions for

a longer period of time.
In case of doubt, please return device to manufacturer for repair
or maintenance.

6. Repairs should only be carried out by the manufacturer. All
other repairs or modifications of the transmitter are unautho­rized.

7. Any operation not described in the following instructions or

2146872 09/2004 GB/D

WIKA Betriebsanleitung Hand-Held Thermometer

WIKA Operating Instructions Hand-Held Thermometer

outside the specifications must not be carried out.

1.2 Operation and maintenance advice

■ Operation with battery or accu
If ∆ and ´bAt´ are shown in the secondary display the battery
has been used up and needs to be replaced, or resp. the accu
is empty and has to be recharged. The device will, however,
operate correctly for a certain amount of time. If ´bAt´ is shown
in the upper display the voltage is too low to operate the device;
the battery or accu has been completely used up.

We recommend to take out battery/accu if device is not used for a
longer period of time!

■ Mains operation with power supply

When using a power supply please note that operating voltage
has to be 10.5 to 12 V DC. Do not apply overvoltage! Cheap
12 V-power supplies often have excessive no-load voltage.
We, therefore, recommend using regulated voltage power
supplies. Trouble-free operation is guaranteed by our power
supply unit.
Prior to connecting the power supply to the mains make sure
that the operating voltage stated at the power supply is
identical to the mains voltage.

■ Connecting/Changing Sensors
Switch off device before changing the sensor. Connect sensor
before switching on the device. In such case take the plug not
at the casing but at the buckling protection at the end of the
plug. When connecting the probe the plug will slide in smoothly
if plug is entered correctly. To disconnect sensor plug do not
pull at the cable but at the plug.

Probes may be extremely hot or cold. Precautions must be
taken to prevent personal injury or damage to objects.

■ Maintenance advice

The digital instrument and sensors are completely of solid state
principle, not containing any moving parts. Dismantling of en­sures invalidates warranty.

If cleaning is necessary, use a cloth damp by a mild soap cleaner,
avoid any solvent or caustic abrasive agent.

As for measurement devices usual, the accuracy of the device
should be tested in regularly time periods (approx. 1 time per year

- see chapter 7).

1.3 Connections

At the top of the device:

are located the socket CH1 for connecting the temperature sensor
of the CPT-series (see chapter 4.1) and the socket for connecting
the interface converter (see chapter 5).

If keys ´Set´ and ´Store´ are pressed simultaneously for more the 2
seconds, the settings are reset of the settings ex-works.

If the logger memory contains data already, the menus/parameters
marked with (*) can not be invoked! If these should be altered the
logger memory has to be cleared before! (see chapter 3)

2. Configuration

To change device settings, press key: ´Set/Menu´ for 2 seconds.
This will call the configuration menu (main display: "SEt").
Pressing key: ´Set/Menu´ changes between the menus, pressing
key: ´Tara´ jumps to the referring parameters, which can be
selected with key: ´Tara´.
The parameters can be changed with key: ´Min´ or ´Max´. Pressing
key: ´Set/Menu´ again jumps back to the main configuration menu
and saves the settings.
Key: ´Store/Quit´ finishes the configuration and returns to stand­ard measuring operation.

2.1 (Unit) Temperature unit

The measured temperature can be displayed in °C or °F.

2.2 (rES) Display resolution

Standard setting: ´Auto´ ,i.e. the device automatically switches over
to the optimum resolution between 0.1 ° and 0.01 °.
If temperatures to be measured are near the switching threshold, a
fixed resolution may be better, e.g. for easy recording.
In such a case please select the optimum resolution manually.

2.3 (Lin E.751) Sensor curve

This function used the standard conversion of resistance to
temperature following EN60751 (Lin E.751).

WIKA Betriebsanleitung Hand-Held Thermometer

WIKA Operating Instructions Hand-Held Thermometer

2146872 09/2004 GB/D

Hand-Held Thermometer
CTH 6200

The sensor curve following EN60751 uses the international
temperature scale ITS90 and following formulas:

Temperatures <0 °C:
R

(T): = 100 [1 + 3,908310-3 * T - 5,77510-7 * T2 - 4,18310

neg

-12

* (T - 100) * T3]

Temperatures >=0 °C:
R

(T): = 100 (1 + 3,908310-3 * T - 5,77510-7 * T2)

pos

2.4 (OFFs) Zero point correction / Offset

A zero point correction can be carried out for the measured
temperature:

temperature displayed = temperature measured - offset

Standard setting: ´off´ = 0.0 °, i.e. no zero point correction will be
carried out. The zero point correction is mainly used to compen­sate for sensor deviations. Unless ´off´ is set, this value will be
displayed shortly after the device is switched on;
during operation it will be identified by means of the offset arrow in
the display.

2.5 (Scal) Scale correction

GB

The scale of the measuring can be influenced by this setting
(factor is in %).

displayed temperature [°C] = measured temperature [°C] * (1 + Scal/100)

or respectively

displayed temperature [°F] = (measured temperature [°C] - 32
°F) * (1 + Scal/100) + 32 °F

Standard setting: ´off´ =0.000, i.e. temperature is nor corrected.
Together with the zero displacement (see above) this factor is
mainly used to compensate for sensor deviations.
Unless the factor is set to ´off´, the Corr arrow in the display shows
an active scale correction.
