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.
In order to avoid any risks arising from interpretation of the measurements in
the concrete application, the user must have additional expertise. The user is
solely liable for dam-
ages/danger resulting from misinterpretation due to inadequate expertise.

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.
- Switch the device off.
- Hold the down button and press the On/Off button briefly to switch on the device and open the Adjustment menu.
- The display shows the first parameter. Release the down button.
Parameter | Values | Meaning |
---|---|---|
T.OF | Zero point correction | |
0.00 | No zero point correction | |
-5.00 … 5.00 | Zero point correction in °C. (at °F -9.00 .. 9.00) | |
T.SL | Gradient correction of the temperature | |
0.00 | No gradient correction of the temperature | |
-5.00 … 5.00 | Gradient correction in % |
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.
- Unscrews the Phillips screws (A)and remove the cover.
- 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.
- The O-ring (C) must be undamaged, clean and positioned at the intended depth.
- Fit the cover (D) on evenly. The O-ring must remain at the intended depth!
- Tighten the Phillips screws (A).

Calibration and adjustment service
The purpose of the calibration is to verify the precision of the measuring
device by comparing it with a traceable reference.
Both ISO calibration certificates and DAkkS calibration certificates are
available from Senseca.
Explanation
-
The ISO standard 9001 is applied for the isocalibration certificates.
-
These certificates area affordable alternative to the DAkkS calibration certificates and provide information of the traceable reference, a list of individual values and documentation.
-
The DAkkS calibration is based on DIN EN ISO/17025, the accreditation basis is recognized worldwide. These certificates offer high-quality calibration and consistently high quality. The DAkkS calibration includes any necessary adjustment with the purpose of minimizing a deviation of the measuring device.
-
The device is delivered with a test report.
This confirms that the measuring device has been adjusted and tested, without making any statement about the accuracy of a temperature sensor. -
Only the manufacturer can check the basic settings and make corrections if necessary.
