UM Temp74 PT100 Vio EN rev.1 19.05.2023
The proper functioning of the device and the safety of the operator are only guaranteed if all normal laboratory
safety regulations are observed and if all specific safety measures described in this manual are followed.
•Basic requirements for safe use
The proper functioning of the device and the safety of the operator are only guaranteed if all of the following
points are observed:
•the instrument may only be used in accordance with the mentioned specifications;
•the instrument must only operate under the environmental conditions described in this manual;
•the only part of the instrument that can be opened by the user is the battery compartment.
Perform other operations only if explicitly authorised by the manufacturer.
•Unauthorised use
The instrument must not be operated if:
•it’s visibly damaged (e.g. due to transport);
•it has been stored for a long period of time under adverse conditions (exposure to direct light, heat sources or
places saturated with gas or vapours) or in environments with conditions other than those mentioned in this
manual.
•Device Maintenance
If used correctly and in a suitable environment, the instrument requires no special maintenance procedures.
It is recommended to occasionally clean the instrument casing with a damp cloth and mild detergent. This
operation should be carried out with the instrument switched off and only by experienced and authorised
personnel. The housing is made of ABS/PC (acrylonitrile butadiene styrene/polycarbonate). This material is
sensitive to certain organic solvents, e.g. toluene, xylene and methyl ethyl ketone (MEK). If liquids were to enter
the housing, they could damage the instrument. Do not open the instrument housing: it contains no parts that can
be serviced, repaired or replaced by the user. In case of problems with the instrument, please contact your local
distributor. It is recommended to use only original spare parts. Contact your local distributor for information. The
use of non-original spare parts can lead to malfunction or permanent damage to the instrument. Furthermore, the
use of spare parts not guaranteed by the supplier can be dangerous for the user.
•Responsibility of the instrument owner
The person who owns and uses the instrument or authorises its use by others is the owner of the instrument and
as such is responsible for the safety of all users of the instrument and third parties. The owner of the instrument
must inform users of its safe use at their place of work and of the management of potential risks and provide the
required protective equipment. When using chemicals or solvents, follow the manufacturer's safety data sheets.

•Offset adjustment
All instruments are factory pre-calibrated and remain stable over time, but in the event of a reading error, the
measuring chain can be recalibrated to eliminate this error.
In the setup menu- Temp Settings- Probe Offset it is possible to adjust the measurement of each individual
channel independently or to align the measurements of all channels to the reference channel.
Example: Single channel calibration at 0.0 °C
To recalibrate the instrument at 0.0°C, proceed as follows:
•prepare ice with double-distilled water;
•put ice cubes in a 500 ml beaker up to half the volume;
•add double-distilled water to ¾ of the volume;
•place the beaker on a magnetic stirrer under gentle agitation;
•immerse the probe in the beaker, ensuring that it is immersed in water and does not touch the beaker wall;
•cover the beaker with polystyrene to isolate the water/ice mixture from the air as much as possible;
•leave to stir for about 10 minutes;
•wait until the temperature reaches 0°C.
If the instrument reads 0.0°C (± measuring chain accuracy), this means that the measuring chain is correctly
calibrated. Otherwise:
•access the Setup menuTemp SettingsOffset probes;
•select the channel to be adjusted;
•the display will show the current temperature, which is to be corrected, and the adjustment value, with
flashing cursor;
•using the keys correct the value to 'Current Temperature' to 0.0 °C;
•press to confirm and record the adjustment.
Note : The adjustment affects the entire measurement scale, e.g. if you correct by -1.0°C, then the
measurement shifts by -1.0°C over the entire range. The setting made in this way remains in memory
both after switching off the instrument and in case of replacement of batteries.
If the sensor is replaced, we recommend resetting the factory calibration from the Temp Settings
menu
 Reset and proceed with a new calibration if necessary. If the sensor is replaced, we recommend resetting
the factory calibration from the Temp Settings menu
 Reset and proceed with a new calibration if necessary.
If there is no probe connected to the selected channel, the offset cannot be changed.
