If these notices are disregarded, personal injury or death, as well as property damage can occur.

Danger! Incorrect area of application!
In order to prevent erratic behavior of the device, personal injury and property damage, the device must be used exclusively as described under intended use.

• Do not use in safety. Emergency Stop devices!
• The device is not suitable for use in explosion-prone areas!
• The device must not be used for diagnostic or other medical purposes on patients!

Safety instructions
Caution! Risk of injury at the temperature sensor!
Empty batteries and batteries of inferior quality can leak more easily, which can destroy the device.

Please also observe the instructions in the chapter “Operation and maintenance”.

Note

• This device does not belong in children’s hands!
• Make sure that no dirt gets into the openings of the sensor head. If this is the case, carefully unscrew the cap. Improper handling can damage the temperature sensor!

Intended use
The device measures the ambient or air temperature; it can be held in the hand (pivoting movement increases the response speed) or placed vertically or horizontally on a flat surface. Protect the sensor from moisture and dirt!

Qualified personnel
For commissioning, operation and maintenance, the relevant personnel must have adequate knowledge of the measuring process and the significance of the measurements. The instructions in this document must be understood, observed and followed.

Adjustment of the measuring input
The temperature input can be adjusted with the zero point correction and the gradient correction. If an adjustment is made, you change the pre-adjusted factory settings.
This is signaled with the display text T.OF or T.SL when switching on.

1. Switch the device off.
2. Hold the down button and press the On/Off button briefly to switch on the device and open the Adjustment menu.
3. The display shows the first parameter. Release the down button.

Formula used by device

Temperature = °C: Display = (measured value – T.OF) (1 + T.SL / 100)
Temperature = °F: Display = (meas. value – 32 °F – T.OF) (1 + T.SL / 100) + 32 °F

Measurement Basics

Measuring instructions
For fast measurements of ambient air: Hold device by the outstretched arm and sway back and forth (to fan) to accelerate the air exchange and the temperature matching.
As soon as the measured value is quite stable, it can be read off. It may make sense to press the hold key to “freeze” all values and therefore read them off easily.

Possible measuring errors

Cooling / evaporation
When measuring the air temperature, the probe should be dry, otherwise the temperature measured will be too low.

Response time
An adequate wait time must be observed for the measuring process before reading the measured value. The response time t90 describes the time in which the displayed measured value reached 90% of the end value.

Heat radiation (e.g. breathing air, body heat, sun)
If the device is held in the hand during the measurement, both temperature and humidity are altered by the body heat. To minimize this influences the device should be held as far away from the sensor as possible and a direct contact with the exhaled air should be avoided. Most accurate measurements are achieved, if the device is set down and the measured value (as soon as it is stable) is read at adequate distance.

When setting the device down, ensure that it is not exposed to any other heat source or, for example, in the sun.

Operation and maintenance

Operating and maintenance notices

Note

• The device and temperature probe must be handled with care and used in accordance with the technical data. Do not throw or strike.
• Plugs and sockets must be protected from soiling.
• If the device is stored at a temperature above 50 °C, or is not used for an extended period of time, the batteries must be removed. Leaks from the batteries are avoid-ed as a result.

Battery

Battery indicator
If the empty frame in the battery display blinks, the batteries are depleted and must be replaced. However, the device will still operate for a certain length of time.
If the BAT display text appears in the main display, the battery voltage is no longer adequate for operation of the device. The battery is fully depleted.

Changing battery

Danger! Danger of explosion!
Using damaged or unsuitable batteries can generate heat, which can cause the batteries to crack and possibly explode!
Only use high-quality and suitable alkaline batteries!

Caution! Damage!
If the batteries have different charge levels, leaks and thus damage to the device can occur.

• Only use high-quality and suitable alkaline batteries!
• Do not use different types of batteries!
• Remove depleted batteries immediately and dispose of them at a suitable collection point.

Note
Unnecessary unscrewing endangers the protection against moisture and should therefore be avoided.

• Read the following handling instructions before replacing batteries and follow them step by step.
• If disregarded, the device could be damaged or the protection from moisture could be diminished.

1. Unscrews the Phillips screws (A)and remove the cover.
2. Carefully replace the two Mignon AA batteries (B). Ensure that the polarity is correct! It must be possible to insert the batteries in the correct position without using force.
3. The O-ring (C) must be undamaged, clean and positioned at the intended depth.
4. Fit the cover (D) on evenly. The O-ring must remain at the intended depth!
5. Tighten the Phillips screws (A).
