2.3 Safety guidelines
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. If the device is transported from a cold to a warm environment condensation may cause in a failure of the func-
tion. In such a case make sure the device temperature has adjusted to the ambient temperature before trying a
new start-up.
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 for a longer time.
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.
Read this document carefully and get used to the operation of the device before you use it. Keep this document
within easy reach near the device for consulting in case of doubt.
3 Product Specification
3.1 Scope of supply
The scope of supply includes:
Device, incl. 9V battery block
Operation Manual
3.2 Operation and maintenance advice
•Battery operation:
If ‘bAt’ is shown in the lower display the battery has been used up and needs to be replaced. However, the device
will operate correctly for a certain time. If ‘bAt’ is shown in the upper display the voltage is too low to operate the
device; the battery has been completely used up.
The battery has to be taken out, when storing device above 50 °C.
We recommend taking out battery if device is not used for a longer period of time.
Treat device carefully. Use only in accordance with above specification. (do not throw, hit against etc.). Protect
plug and socket from soiling.
Make sure that sensor and device are always subjected to the same temperature, i.e. try to avoid holding sensor
plug in your hand for a longer period of time as well as subjecting device to an additional heat source as this may
result in measuring inaccuracies.

4 Notes to Functions of Device
4.1 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 measuring.
4.2 MIN-/MAX Value Memory
watch MIN value (Lo): press key ‘Mode‘ shortly once display changes between ‘Lo‘ and MIN
value
watch MAX value (Hi): press key ‘Mode‘ shortly once again display changes between ‘Hi‘ and MAX
value
restore current value: press key ‘Mode‘ shortly once again current value is displayed
clear MIN-/MAX- value: press key ‘Mode‘ for 2 seconds MIN and MAX value are cleared. The dis-
play shows shortly ‘CLr‘.
4.3 Hold –Function
By shortly pressing the ‘Hold‘ key the currently measured value is ‘frozen‘,
The display changes between ‘Hld‘ and the ‘frozen‘ value
Pressing the key ‘Hold‘ shortly once again resets the display to the current value.
Please note: Measuring keeps on running in the background, the MIN/MAX values are updated continuously.
4.4 Offset and Scale Adjustment
The offset and scale adjustment is mainly intended to be used to compensate errors of the external tem-
perature probes.
The display value is given by following formula:
unit = °C: Display = (measured value - offset) * ( 1 + scale adjustment [%] )
unit = °F: Display = (measured value - 32°F - offset) * ( 1 + scale adjustment [%] ) + 32°F
To adjust a measuring offset and scale proceed like follows:
1. Switch off the instrument.
2. Press the ‘Hold‘ key while switching on the instrument.
Keep ‘Hold‘ key pressed until ‘OFS‘ appears in the display (about 3 seconds).
3. Press ‘Mode‘ or ‘Hold‘ key, the currently selected offset adjustment appears.
4. Choose the desired value by pressing ‘Mode‘ or ‘Hold‘ key. (max. input range: ±5.0°C or ±9.0°F)
5. Enter by pressing On/Off-key: SCL appears in the display
6. Press ‘Mode‘ or ‘Hold‘ key, the currently selected scale adjustment appears
7. Choose the desired value by pressing ‘Mode‘ or ‘Hold‘ key. (max. input range: ±5.00%)
The input is displayed in %.
example: scale adjustment is 4.00 => scale is increased by 4.00% => Scale = 104%
At a measured value of 100.0 (without offset correction) the instrument would show 104.0
8. Store the values by pressing ‘On/Off‘ key.
Please note: If during the changing of the offset adjust no key is pressed within 20 seconds, the input
will be aborted. Eventually made changes won’t be stored!

5 Configuration Of The Instrument:
To configure the instrument proceed like follows:
1. Switch off the instrument.
2. Press the ‘Mode‘ key while switching on the instrument, keep ‘Mode‘ key pressed until ‘PoF‘ appears (about
3 seconds).
5.1 Auto Power Off Time
The auto power off time is entered in minutes. If no key is pressed during a measuring, the instrument switches itself
off automatically after the entered period of time.
3. Press ‘Mode‘ or ‘Hold‘ key, the currently selected power off time will be displayed (off, 1..120min)
4. Enter the desired time by pressing ‘Mode‘ or ‘Hold‘ key.
Possible input: off: The auto power off function is deactivated (permanent operation)
1...120: auto power off time in minutes.
5. Confirm the value by pressing ‘On/Off‘ key, ‘Uni‘ appears in the display
5.2 Display Unit: Choice of the temperature display unit °C or °F
6. Press ‘Mode‘ or ‘Hold‘ key, the currently selected unit will be displayed (°C or °F)
7. Enter the desired unit by pressing ‘Mode‘ or ‘Hold‘ key.
8. Confirm the value by pressing ‘On/Off‘ key, ‘rES‘ appears in the display
5.3 Display Resolution: Choice of the temperature display resolution 1° or 0.1°
9. Press ‘Mode‘ or ‘Hold‘ key, the currently selected resolution will be displayed (1° or 0.1°)
10. Enter the desired resolution by pressing ‘Mode‘ or ‘Hold‘ key.
0.1°: Display 0.1°C or 0.1°F. When exceeding the display range (>199.9°) the display automatically changes
to 1° resolution
1°: Display with 1°C or 1°F resolution
11. Confirm the value by pressing ‘On/Off‘ key. The vales will be stored, the instrument will restart (segment test).
Please note: If during the configuration no key is pressed within 20 seconds, the configuration will be
aborted. Eventually made changes won’t be stored!
6 System Messages:
Er. 1 = measuring range has been exceeded
Er. 2 = meas. values have fallen below perm. range
Er. 7 = System fault - the device has detected a system fault (defective or far outside allowable ambient tem-
perature range)
--- = No temperature probe connected or probe defective
If the symbol "BAT“ is displayed at the left side of display, the battery is weak, measuring can be continued for a
certain time. If “bAt“ is displayed in the main display the battery is used up and needs to be replaced. Measuring is
no more possible.
