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. Inter-
nal connection in third party devices may result in not-permis-
sible 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).
5. If there is a risk whatsoever involved in running it, the device
has to be switched off immediately and to be marked accor-
dingly 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 unautho-
rized.
7. Any operation not described in the following instructions or
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 en-
sures 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).

At the left side of the device:
is located the mains adapter socket to connect the available
power supply unit (see valid price list of CTH 6200).

1.4 Display
1. Offset: indicates that zero point offset (offset) is activated.
2. Corr: indicates that correction factor is activated.
3. : indicates a low battery and other warnings.
4. Logg: Shown if logger function is selected, flashes if cyclic
logger is running.
5. AL: Flashes if alarm is present.
6. Main display: Currently measured temperature.
7. Min/Max/Hold: shows if a MIN, MAX or Hold value is displayed
in the secondary display.
8. Secondary display: shows MIN, MAX or Hold value acc. to
selected function.
1.5 Basic operation
When switching on the device and the logger function is not off
the time of the integrated clock will shortly be displayed. If a zero
point adjustment was carried out the display shows shortly "nuLL
Corr".
After changing the battery the clock-setting menu is activated
automatically (´CLOC´). Check the clock and adjust, if necessary
(see chapter 2).
