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). 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.
2146872 09/2004 GB/D
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.

1.2 Operation and maintenance advice
GB
■ 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.
2146872 09/2004 GB/D
Probes may be extremely hot or cold. Precautions must be taken to prevent personal injury or damage to objects.

Hand-Held Thermometer CTH 6200 If keys ´Set´ and ´Store´ are pressed simultaneously for more the 2 seconds, the settings are reset of the settings ex-works.
GB
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
2146872 09/2004 GB/D
This function used the standard conversion of resistance to temperature following EN60751 (Lin E.751).
12
WIKAWIKA Operating Betriebsanleitung Instructions Hand-Held Thermometer
Hand-Held Thermometer CTH 6200 The sensor curve following EN60751 uses the international temperature scale ITS90 and following formulas:
GB
Temperatures <0 °C: Rneg(T): = 100 [1 + 3,908310-3 * T - 5,77510-7 * T2 - 4,18310-12 * (T - 100) * T3] Temperatures >=0 °C: Rpos(T): = 100 (1 + 3,908310-3 * T - 5,77510-7 * T2)
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 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
2146872 09/2004 GB/D
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.

2.6 (P.oFF) Power off function If there won't be pressed any key and no interface communication takes place for the time of the power off time setting (P.off), the device will be switched off automatically to save battery power. If P.oFF = oFF then the automatic switch off is deactivated. 2.7 (Out) Serial interface The output can be used as serial interface. If none needed, we suggest to switch the output off, because battery life then is extended. 2.8 (Adr.) Interface base address In preparation for use with multiplexer. 2.9 (AL.) Alarm There are three possible settings: Alarm off (AL. oFF), on with horn sound (AL. on), on without horn sound (AL. no.So). Following conditions will display an alarm, when the function is activated (on or no.So): ■ Value is below lower (AL. Lo) or above upper alarm rail (AL.Hi). ■ Sensor error (Sens Erro) ■ Low battery (bAt) ■ Fe 7: System error (always with sound) In case of an alarm, the alarm arrow flashes, and when polling the interface the prio-flag is set in the returned interface message.
The real time clock is used for the logger function: Recorded values are also containing the point of time, when they were measured. Please check the settings when necessary. If the battery was replaced the referring menu ´CLOC´ will automatically be started.

3. Operation of logger The device supports two different logger functions: "Func-Stor": each time when the key: ´Store/Quit´ is pressed a measurement will be recorded. "Func-CYCL": measurements will automatically be recorded each interval, which was set in the logger menu ´CYCL´ until the logger will be stopped or the logger memory is full. The recording is started by pressing key: ´Store/Quit´ for 2 seconds. The logger records 1 measurement result each time. For the evaluation of the data the WIKA Data logger evaluation software GSOFT (V 1.7 or higher) has to be used. The software also allows easy configuration and starting of the logger. When the logger is activated (Func Stor or Func CYCL) the hold function is no more available, the key: ´Store/Quit´ is solely used for the operation of the logger functions.
3.1 Func-Stor": Storing single measurements Each time when key: ´Store/Quit´ is pressed a measurement and its time stamp will be recorded. The recorded data can be viewed either in the display (when calling the configuration an additional menu "REAd LoGG" is displayed, see below) or by means of the interface and a PC with GSOFT-software. Max. number of measurings:
99
A measuring max. contains:
2146872 09/2004 GB/D
■ Current measuring value at the time of recording ■ Min.-Peak, Max.-Peak since last recording ■ Time and date of the recording After each recording "St. XX" will be displayed for a short time. XX represents the number of the recording.

4. General information about temperature sensors ■ Heat loss caused by probe construction: Especially when measuring temperatures which deviate very much from the ambient temperature, measuring errors often occur if the heat loss caused by the probe is not considered. When measuring fluids therefore the probe should be emerged sufficiently deep and be stirred continuously. When measuring gases the probe should also emerge as deep as possible in the gas to be measured (e.g. when measuring in channel/pipes) and the gas should flow around the probe at sufficient flow. The tube length should be selected long enough, that temperature keeps low at the handle. ■ Self Heating The measuring current of the instrument is just 0.3 mA. Because of this comparably low current practically no self heating effect has to be considered, even at air with low movement the self heating is <= 0.01 °C. ■ Cooling by Evaporation When measuring air temperature the probe has to be dry. Otherwise the cold due to the evaporation causes too low measurings.
4.1 Available sensors The device is designed to be connected to all sensors of the CTH6200 series (see valid price list CTH6200).
By means of the serial interface and a suitable electrically isolated interface adapter the device can be connected to a computer for data transfer (USB-adapter on request), to visualise the data with the WIKA Datalogger evaluation software GSOFT (see valid price list CTH6200). To avoid transmission errors, there are several security checks implemented e.g. CRC.
