1 Safety
1.1 General note
Read through this document attentively and make yourself familiar to the operation of the device before you
use it. Keep this document in a ready-to-hand way in order to be able to look up in the case of doubt.
Mounting, start-up, operating, maintenance and removing from operation must be done by qualified,
specially trained staff that have carefully read and understood this manual before starting any work.
The manufacturer will assume no liability or warranty in case of usage for other purpose than the intended
one, ignoring this manual, operating by unqualified staff as well as unauthorized modifications to the device.
The manufacturer is not liable for misprints.
1.2 Intended Use
The device is designed for temperature measurements in various media in seconds.
The measuring range is -50... +1150 °C.
The device has a 2-pole standard flat-plug connection suitable for all type K thermocouple probes. Refer to
chapter 6 Type K-sensor to view a selection of the available probes.
The safety requirements (see below) have to be observed.
The device must be used only according to its intended purpose and under suitable conditions.
Use the device carefully and according to its technical data (do not throw it, strike it …)
Protect the device from dirt.
1.3 Qualified staff
All instructions have to be well understood and complied with.
To be sure that there´s no risk arising due to misinterpretation of measured values, the operator must have
further knowledge in case of doubt - the user is liable for any harm/damage resulting from misinterpretation
due to insufficient knowledge.
1.4 Safety signs and symbols
Warnings are labeled in this document with the followings signs:
Caution! This symbol warns of imminent danger, death, serious injuries and significant
damage to property at non-observance.
Attention! This symbol warns of possible dangers or dangerous situations which can
provoke damage to the device or environment at non-observance.
Note! This symbol point out processes which can indirectly influence operation, possibly
cause incorrect measurement or provoke unforeseen reactions at non-observance.

1.5 Reasonably foreseeable misuse
This device must not be used at potentially explosive areas!
Do not use these products 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.
This device must not be used at a patient for diagnostic or other medical purpose.
1.6 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.
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.
Due to the pointed probe design there is a risk of stitch injury for devices with insertion
probe.
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 0
Specification.If the device is transported from, a cold to a warm environment condensation
may cause 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.

2.2 Operating and Maintenance
Battery operation:
If the "BAT" symbol is displayed at the bottom left of the display, the battery is weak and should be replaced
soon. However, the device will still operate for a certain length of time.
If an additional "BAT" symbol is shown in the display, the battery is depleted. Battery replacement: (see
chapter 7 Fehler! Verweisquelle konnte nicht gefunden werden.).
The battery has to be removed, when storing device above 50°C.
We recommend taking out the batteries if device is not used for a longer period of time.
Treat device and probes carefully. Use only in accordance with above specification. (do
not throw, hit against etc.). Protect plug and socket from soiling.
Make sure that the device and the probe plug are always exposed to the same
temperature. Therefore, do not hold the probe plug in your hand too long and do not
expose the device to an additional heat source; otherwise faulty measurements can occur.
Wire probes, e.g.: GTF 300 can be shortened or, in case of a break, repaired by stripping
about 10mm of the insulation off of the wire ends and twisting them together.
Measurement is not possible with open wire ends.

4 Adjustment
The device is calibrated and adjusted at the factory so that any standard probe offered by Greisinger can be
plugged in without recalibration. If the value deviates excessively over time, we offer factory re-calibration.
4.1 Manual Adjustment
Manual adjustment changes the factory settings, which can no longer be simply restored!
If you want to adjust the device to the available probe, the probe must be plugged in first. Then the zero-
point potential must be adjusted. See chapter Fehler! Verweisquelle konnte nicht gefunden werden.
Connections.
Ensure that the thermometer has adjusted to room temperature for the zero-point
potentiometer adjustment!
4.1.1 Zero point-Adjustment
Put ice cubes in a glass and pour cold water until ice cubes are almost covered. Put sensor into glass, wait
approx. 30 minutes, then stir water with a spoon handle. Wait for stable value to be displayed, and then turn
zero point potentiometer by means of a screwdriver until display shows 0.
4.1.2 Scale Adjustment
An additional temperature reference is required for the scale adjustment. Adjust the display with the gradient
potentiometer (scale) to the desired reference value.

Validity
1
K
+/- 1.5 °C
-40… +375 °C
5.2 Possible errors
5.2.1 Immersion depth
For measurements in liquids the probe should be immersed sufficiently deep (depending on probe
diameter, at least 20 mm with Ø 3 mm and 10 mm with Ø 1.5 mm) and subsequently stirred.
When measuring gases the probe should also emerge as deep as possible in the gas to be
measured (e.g. when measuring in channels/pipes) and the gas should flow around the probe at
sufficient flow.
5.2.2 Surface effects and bad heat transfer
For surface temperature measurements special surface probes are necessary. Surface quality, heat
transfer and ambient temperature have an influence on the measurement result.
Thermally conductive paste between the probe and surface can also increase
measurement accuracy in some cases.
5.2.3 Cooling (evaporation)
For air temperature measurements, the probe should be dry, otherwise it can be possible that a too
low temperature could be measured.
5.2.4 Response time
Before reading the measured value at the measuring process, it is necessary to wait a sufficient time
(see chapter 6 Type K-sensor).

5.2.5 Limit values
If this is disregarded, the probe can be destroyed!
Thermocouples are suitable for detecting very large temperature ranges. However, the permissible limits of
your probe must be observed when measuring high temperatures. See chapter 6 Type K-sensor.

7 Replacing batteries
The use of damaged or unsuitable batteries could lead to further heating, whereby the
batteries can burst or in the worst case exploding.
Ensure that the device is switched off when replacing the battery. The switch must be in Position 0, see
chapter Fehler! Verweisquelle konnte nicht gefunden werden. Fehler! Verweisquelle konnte nicht ge
funden werden. and turn it over so that the rear side is facing upwards.
1.) Open the cover of the device by carefully pushing it off of the device.
2.) Pull the battery out of the compartment and disconnect it.
3.) Ensure correct polarity when replacing the battery!
4.) Insert the battery in the compartment. Then position the cover correctly and slide it in until it engages.
