1. INTENDED USE

This product is designed for temperature measurement and is especially suitable for use in laboratories and industrial areas. Temperature measurement is done via two temperature sensors. Temperature can be measured with temperature sensors of type K and J. Measurement readings can be frozen on the screen. The product can display the minimum, maximum and average readings of a particular measurement process. Temperature can be displayed in C (Celsius), F (Fahrenheit) or K (Kelvin). The product can calculate the difference between two temperature readings and display the result. The product features an auto-off and a backlight function. Power is supplied by three AAA batteries. Measurements should not be carried out under unfavourable ambient conditions. Adverse conditions are: Moisture or excessive humidity Dust and flammable gases, vapours or solvents. Thunderstorms or similar conditions such as strong electrostatic fields, etc. This product fulfils European and national requirements related to electromagnetic compatibility (EMC). CE conformity has been verified and the relevant statements and documents have been deposited at the manufacturer. Unauthorised conversion and/or modification of the device are inadmissible because of safety and approval reasons (CE). Any usage other than described above is not permitted and can damage the product and lead to associated risks such as short-circuit, fire, electric shock, etc. Please read the operating instructions thoroughly and keep them for further reference.

5. INSERTING / REPLACING BATTERIES
1. Unscrew the screw on the battery compartment cover using a Phillips screwdriver and take off the cover of the battery compartment. 2. Insert three AAA batteries, observing the correct polarity. Take note of the labelling on the inside of the battery compartment. 3. Close the battery compartment. Replace the batteries when the battery icon appears on the display.

3. SAFETY INSTRUCTIONS

We do not assume liability for resulting damages to property or personal injury if the product has been abused in any way or damaged by improper use or failure to observe these operating instructions. The warranty/ guarantee will then expire! The icon with exclamation mark indicates important information in the operating instructions. Carefully read the whole operating instructions before operating the device, otherwise there is risk of danger.

Persons / Product

The product is not a toy and should be kept out of reach of children! When used in conjunction with other devices, observe the operating instructions and safety notices of connected devices. Protect the product from extreme temperatures, direct sunlight, strong jolts, high humidity, moisture, flammable gases, vapours and solvents. Do not place the product under any mechanical stress. If it is no longer possible to operate the product safely, take it out of operation and protect it from any accidental use. Safe operation can no longer be guaranteed if the product: -- is visibly damaged, -- is no longer working properly, -- has been stored for extended periods in poor ambient conditions or -- has been subjected to any serious transport-related stresses. In schools, training facilities, hobby or self-service workshops, handling of electrical devices must be monitored by trained personnel. When operating on commercial premises, the relevant accident prevention regulations of workers compensation boards for electrical equipment must be observed. Make sure there are no devices with strong electric or magnetic fields such as transformers, motors, cordless telephones and radio-controlled devices in the vicinity of the product as these can influence the product. Do not switch the product on immediately after it has been taken from a cold to a warm environment. The condensation that forms might destroy the product. Allow the product to reach room temperature before switching it on.

6. operation

Do not measure the temperature of live parts or leads, as touching them might cause a potentially lethal electric shock. Also, the thermometer and sensors could be damaged. The sensors included with delivery can only be used for measurements in dry environments and on surfaces with a temperature of > -20 C and < +250 C. They are not suitable for use in humid environments or to measure the temperature of fluids. The accuracy of the gauge is only assured when the thermometer is operated at a temperature range of +18 C to +28 C (excluding the temperature sensors). The thermometer (excluding the temperature sensors) must not be used outside the operating temperature range. Please note the specifications on operating temperature in the Technical Data section. You can utilize the entire measurement range of the thermometer with optionally available temperature sensors.

1. Press and hold the SET button for approx. two seconds. SETUP will appear on the top left corner of the display. TYPE will appear on the bottom left corner. 2. Press the ENTER button to select the temperature sensor type. 3. Using the HOLD or MAX/MIN buttons, you can switch between types K and J. Confirm your selection by pressing the ENTER button. The display will show SLP. 4. Press the ENTER button to activate/deactivate the auto-off function. 5. Using the HOLD or MAX/MIN buttons, you can switch between SLP ON (auto-off function on, clock symbol appears top-right in display) and SLP OFF (auto-off function off, clock symbol no longer displayed). Confirm your selection by pressing the ENTER button. The display will show T1. 6. Press the ENTER button to compensate any deviation (OFFSET) in measurement accuracy of sensor T1. 7. Press the HOLD or MAX/MIN buttons to set any deviation adjustment ( 5 C; 9 F/K). The displayed reading changes accordingly. Confirm your selection by pressing the ENTER button. The display will show T2. 8. Proceed as described above to compensate a deviation in measurement accuracy of sensor T2. You can find further details in the section Determining deviation of a sensors measurement accuracy. 9. To return to the normal display mode, press and hold the SET button for approx. two seconds. If you only want to make a specific adjustment, press and hold the SET button and select the required point using the HOLD or MAX/MIN button. Then press the ENTER button and make the adjustment.
Determining deviation of a sensors measurement accuracy

Basic functions

1. Connect the temperature sensors to ports T1 and T2 on the top of the device. You may also connect just one temperature sensor. Only one direction is possible. Please note the polarity labelling on the temperature sensors plugs and on the side of the ports. You can also connect temperature sensors of type J to the thermometer; these are optionally available. 2. Press the on/off button to switch the device on. 3. Place the sensors at the locations which you want to measure. 4. The display will show the temperature readings (T1 top, T2 underneath). If no temperature sensor is connected, four horizontal bars will be displayed instead of a temperature reading. 5. Press the CFK button to switch between Celsius (C), Fahrenheit (F) and Kelvin (K).
1. Turn the thermometer on and place the relevant sensor in an optional temperature calibrator or in any other reference location with a known and stable temperature. 2. Wait until the thermometers display has stabilised. 3. If there is a difference, you can manually compensate it (see section Adjusting settings).
7. MAINTENANCE AND CLEANING
No maintenance is necessary for the device apart for occasional cleaning and the changing of the battery. Clean the exterior of the device with a soft, dry cloth or brush only. Never use aggressive or chemical cleaning agents, since this might damage the surface of the housing or impair operation.
