Function/Application
The digital thermometer is used to measure temperature and temperature differences with the aid of exchangeable type K thermocouples/sensors. The digital thermometer is predominantly used for temperature measurement in laboratories and in industrial applications. With the aid of the MAX function, it is possible to determine limit temperature infringements in extended series of measurements. The 1/4“ tripod connection provides a flexible locking facility for stationary setups.

• Only hold the test prods by the handles. Do not touch the test prods, they can become very hot during the measuring procedure.
• Wherever possible the test prods should not be operated with an external voltage supply; if this is unavoidable pay particular attention to the maximum voltage with respect to earth potential and the maximum voltage between the two inputs T1 and T2. To avoid damaging the device, the external voltage supply must not be higher than 24 V AC or 60 V DC. Please note that the test prods are electrically conductive and may irreparably damage the test piece when measuring in connection with an external voltage supply.
• Use under high voltages or under high electromagnetic alternating fields can have an influence on the measuring accuracy.
• The device must only be used in accordance with its intended purpose and within the scope of the specifi cations.
• If you are working with voltages higher than 24 V AC/60 V DC, exercise extreme caution. Touching the electrical conductors at such voltages poses a risk of life-threatening electric shocks.
• If the device comes into contact with moisture or another conductive residue, work must not be carried out under voltage. When using the device outdoors, make sure that the weather conditions are appropriate and/or that suitable protection measures are taken.
• The measuring tools and accessories are not toys. Keep out of reach of children.

General information

• If the thermometer is subject to large fluctuations in the ambient temperature, after the temperature has stabilized, wait 20 minutes before performing a measurement.
• Always ensure adequate thermal coupling at the measuring point in order to avoid measuring errors caused by temperature loss.
• Please note that all thermometers with a contact sensor infl uence the measurement and their thermal capacity can reduce the actual temperature. More thermal energy should therefore be applied to the thermocouple than it can dissipate.
• OL is shown in the display when no measuring sensor is connected.
• The thermometer shows OL when the measured temperature is outside the measuring range.
• Only use the correct types of thermocouples plugged in at the K-type connection; the wrong type of thermocouple can cause considerable measuring errors.
• In addition to being subject to aging, a thermocouple is also greatly dependent on the operating conditions and should therefore be checked regularly.
•  High pressure or mechanical deformation can change the grid structure and therefore have an  infl uence on the thermoelectric voltage output.

4 Temperature measurements (T1, T2, T1-T2)
The temperature T1 or T2 is measured and displayed by pressing buttons „T1“ or „T2“. A thermocouple (type K) must be plugged in at connection T1 or T2. The differential temperature can be determined by pressing the button „T1-T2“ when thermocouples are plugged in at both connections.

The maximum temperature in an extended series of measurements is determined by pressing the „MAX“ button. The HOLD function shows the last measurement or measured value in the display.
6 Measured value resolution (0.1 °C/1.0 °C)
This function changes the measurement resolution is changed between 0.1 °C and 1.0 °C. The resolution of 0.1 °C is particularly useful for measurements ≤100 °C where it is necessary to determine the temperature exactly. A  resolution of 1.0 °C is recommended for measuring higher temperatures.
**!**  The device should be checked regularly to ensure it is functioning correctly. Calibration intervals of 1 year are recommended.
