Features and functions

  •  The hand thermometers K101 and K102 are robust and precise devices for the measurement of temperature by optional K-type thermocouples.
  •  All commercial K-type thermocouples can be connected to the devices via a standard blade terminal. A selection of various thermocouples (temperature sensors) can be found in our catalogue.
  •  The K101 comes with one input port for the thermocouple and the K102 with two input ports.
  •  The maximum temperature range for these devices is -200 °C to +1370 °C or -328 °F to +2498 °F, depending upon the respective temperature sensor.

Safety instructions

Read the operating instructions carefully and especially observe the safety information. If you do not follow the safety instructions and information on proper handling in this manual, we assume no liability for any resulting personal injury or damage to property. Such cases will invalidate the warranty/guarantee.

General information

  •  The device is not a toy. Keep it out of the reach of children and pets.
  •  Do not leave packaging material lying around carelessly. This may become dangerous playing material for children.
  • 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.
  • Please handle the product carefully. Jolts, impacts or a fall even from a low height can damage the product.
  •  Consult an expert when in doubt about the operation, safety or connection of the appliance.
  •  Maintenance, modifications and repairs must only be completed by a technician or an authorised repair centre.
  •  If you have questions that remain unanswered by these operating instructions, contact our technical support service or other technical personnel.
  • Never exceed the maximum input limits.
  •  In commercial facilities, the electrical equipment safety regulations from the German Federation of Insti-tutions (HVBG) are to be observed.

Batteries

  • Correct polarity must be observed while inserting the battery.
  • The batteries should be removed from the device if it is not used for a long period of time to avoid dam-age through leaking. Leaking or damaged batteries might cause acid burns when in contact with skin, therefore use suitable protective gloves to handle corrupted batteries.
  • Batteries must be kept out of reach of children. Do not leave batteries lying around, as there is risk, that children or pets swallow them.
  • All batteries should be replaced at the same time. Mixing old and new batteries in the device can lead to battery leakage and device damage.
  •  Batteries must not be dismantled, short-circuited or thrown into fire. Never recharge non-rechargeable batteries. There is a risk of explosion!
  • Do not leave the battery lying around, there is a danger that a child might swallow it. Batteries that have expired or been damaged can cause skin burns. Do not throw batteries into the fire!

Operation

Inserting/changing the battery
The hand thermometer requires a 9V block battery to operate. When the battery is empty the display “Low Battery ” (14) will appear in the LCD display. The battery will need to be replaced as a correct display cannot be made when the battery is low.
The procedure for changing the battery is as follows:

  1. Disconnect the device from the temperature sensor/s and turn it off.
  2. Open the battery compartment (10) by pushing the battery compartment cover towards the bottom.
  3. Remove the empty battery and replace it with a new battery.
  4. Replace the battery compartment cover.

Switching on/off
Press the On/Off button (4) to switch the hand thermometer on or off.

Connecting the temperature sensors
Connect a commercial K-type temperature sensor to the input T1 (1) and T2 (2) (only for K102). If the temperature sensor is defective or not properly connected, “—-” will appear in the LCD display.

  • Take note that the maximum input voltage at the input, 60V/DC or 24V/AC, must not be exceeded!

Selecting the temperature unit °C/°F
When the hand thermometer is switched on the temperature is shown in degrees Celsius. To change the temperature to degrees Fahrenheit press the °C/°F button (8). To display the temperature back in degrees Celsius press the °C/°F button (8) once again.

Data-Hold function
The hand thermometer is equipped with a Data-Hold function. This allows the current temperature reading in the display to be “frozen”. To freeze the temperature reading press the hold button (6). When activated the Data-Hold function will be indicated in the LCD display with the “hold” symbol “ H ” (11). The hand thermometer continues to read the current temperature in the background. To deactivate the Data-Hold function, press the hold button (6) once again – the hold symbol “ H ” (11) will be extinguished. In the LCD display the current temperature will now be displayed.

  • When the Data-Hold function is activated, the Relative and MIN/MAX functions as well as the °C/°F switch are no longer accessible.

Relative function
The hand thermometer is equipped with a Relative function. By pressing the Δ Rel-button (17) the hand thermometer will register the temperature at the pressing of the Δ Rel-button (17). The difference between the temperature read-ings will be indicated in the LCD display. To deactivate the relative function, press the Δ Rel-button (17) once again.

Max/Min function
The hand thermometer is equipped with a Max/Min function. This function records the lowest (Min) and the highest (Max) temperatures during the measurement. As a result processes can be easily monitored. By pressing the Max/Min button (5) you will reach the Max/Min function. Through repeated pressing of the Max/Min button (5) you can scroll though the various temperatures (Min/Max/Current).

When “MAX” (13) is displayed, the highest temperature recorded will be shown, when “MIN” (12) is displayed, the lowest. When “MAX MIN” blinks simultaneously in the LCD display, the current temperature will be shown – the maximum and minimum temperature values will however continue to be updated and recorded.
To leave the Min/Max function press and hold the Max/Min button for approximately two seconds.

Deactivating the automatic shut off
In order to save the batteries, the device is equipped with an automatic power-off function (automatic shut off). If the device is not operated for more than 30 minutes it will automatically shut off. The automatic shut-off is activated when the hand thermometer is switched on. When activated, the automatic shut-off is signaled in the LCD display with the automatic power-off symbol “ ”.

To deactivate this function switch the hand thermometer off. Press and hold the Hold button (6) while switching the hand thermometer back on. The automatic shut-off is now deactivated and the automatic power-off symbol “ ” will be extinguished.

Calibration
The hand thermometer is calibrated in the factory. For precise measurements, the hand thermometer can be set to the respective temperature sensor. Hold the temperature sensor in a container of icy water (0 °C). Check the hand thermometer’s display after approximately one minute. If it does not read 0 °C it can be correctly set by turning the offset calibration screw (9). For more precise measurements the hand thermometer can be set with an optional thermocalibrator.

Care and cleaning

  • Do not use any aggressive cleaning agents, rubbing alcohol or other chemical solutions as they can cause damage to the housing and malfunction.
  • Remove batteries from the device when it is not to be used for an extended period.
  • Clean the product with a dry, fiber-free cloth.
  • Maintenance or repairs must be carried out by qualified personnel.
