If the device is transported from a cold to a warm environment condensation may result 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.
2. If device is to be connected to other devices the circuitry has to be designed most carefully. Internal connection in third party
devices (e.g. connection GND and earth) may result in not-permissible voltages impairing or destroying the device or another
device connected.
3. 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. 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
In case of doubt, please return device to manufacturer for repair or maintenance.
4. Warning: Do not use this product as safety or emergency stop devices or in any other application where failure of the product
could result in personal injury or material damage.
Failure to comply with these instructions could result in death or serious injury and material damage.
5. The battery has to be taken out, when storing device above 50°C.
It is recommended to take the battery out, when storing device for a longer period of time.

In General: Measuring Temperature With Thermocouples
Temperature differences between the instrument and the probe connector may produce measuring errors. Therefore wait after
connecting or touching the connector until the temperatures have adjusted. (can take up to 15 mins. )
The device is suitable to measure large temperature ranges. But consider the allowable range of Your probe!
When measuring air temperature the probe has to be dry. Otherwise the cold due to the evaporation causes to low measurings.

Please note: Measuring keeps on running in the background, the MIN/MAX values are updated continuously.
Offset and Scale Adjustment
The offset and scale adjustment is mainly intended to be used to compensate errors of the external temperature probes.
The display value is given by following formula:
unit = °C: Display = (measured value - offset) * ( 1 + scale adjustment / 100 )
unit = °F: Display = (measured value - 32°F - offset) * ( 1 + scale adjustment / 100 ) + 32°F
To adjust a measuring offset and scale proceed like follows:
1. Switch off the instrument.
