2.2 Operating and Maintenance
Battery operation:
If the battery has been used up and needs to be replaced, the empty frame of the battery symbol starts
blinking. The device will, however, continue operating correctly for a certain time.
The battery has been completely used up, if ´BAT ´ is shown in the main display.
Battery replacement: (see chapter 8 Adjustment of temperature input).
Temperature measuring / probe connection:
To optimize the accuracy, an offset and a slope correction can be executed, (take a look at chapter 8).
Treat device and probes carefully. Use only in accordance with above specification. (do
not throw, hit against etc.). Protect plug and socket from soiling.
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.

3.3 Connections
BNC- socket:
connection for temperature probe
Usage of BNC plug:
Lock/ unlock with turnable ring at cable
socket.
The connections are only waterproofed when a plug declared as waterproof is connected
4 Start operation
Be sure that suitable batteries are inserted (see chapter 10 Replacing batteries).
Turn device on via key “on/off”.
After segment test the device displays some information about his configuration in the “auxiliary display”:
T.OF If there are made a zero point correction for the temperature (see chapter 8 Adjustment of temperature input).
T.SL If there are made a slope correction for the temperature probe (see chapter 8 Adjustment of temperature
input).
POFF If “auto-power-off” is active - after the set time the instrument is switched off if no key is pressed (see chapter
7 Configuration).
When using interchangeable probes the accuracy of the whole measuring instrument can be
optimized with slope- and zero point correction. (see chapter 8 Adjustment of temperature
input).
Attention: If a correction is done this is only suitable for this specific probe.
After that the device is ready for measuring.
5 Basics of the measurement
5.1 Possible errors
5.1.1 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.
5.1.2 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.
5.1.3 Cooling (evaporation)
For air temperature measurements, the probe should be dry, otherwise it can be possible that a too
low temperature could be measured.
5.1.4 Response time
Before reading the measured value at the measuring process, it is necessary to wait a sufficient time
(see chapter 13 Specification –Response time 90).

H86.0.04.6C-01 Operating Manual Gourmet Thermometer Page 8 von 14
_____________________________________________________ _____________________________________________________________________________
6 Temperature probe
6.1 Probe accuracy/device accuracy
The device can be equipped with different interchangeable temperature probes. These are classified into the
following classes (EN 60751):
Class
Maximum deviation
Are of validity
B
± 0.3 °C at 0 °C ± 0.5 % of measured value
-50 … 250 °C
A
± 0.15 °C ± 0.2 % of measured value
-30 … 250 °C
AA (=1/3 DIN B)
± 0.1 °C ± 0.17 % of measured value
0 … 150 °C
To receive high exchange accuracy without necessity of additional adjustment (see chapter 8 Adjustment of
temperature input) we recommend the usage of temperature probes from the class “A” or “AA”.
Do not touch the hot temperature sensor or cable during the cooking process or directly
thereafter with your bare hands. Always wear heat-resistant gloves.
6.1.1 Extra-thin insertion sensor
GF 2T Pt1000 –Precise, waterproof, extra-thin Class
B insertion sensor for quick measurements. Is
suitable for use in gases, liquids and soft plastic
materials. The stainless steel tube of the extra-thin
insertion sensor is designed for permanent contact
with food.
6.1.2 Durable insertion sensor
GF 3T Pt1000 –The Class B insertion sensor is
suitable for use in gases, liquids and soft plastic
materials. The stainless steel tube of the insertion
sensor is designed for permanent contact with foods.
The 1-metre-long glass fibre insulated cable is
encased with a stainless steel braided jacket, heat-
resistant to 400 °C and equipped with a BNC plug
connector. Ideal for long-term measurements in
ovens or grills.
It can be cleaned with a damp cloth.
Water or moisture in the cable can cause produce faulty measurements. The error can be
corrected by drying the cable.

Slope correction of temperature measurement in [%]
The temperature input can be adjusted with offset (T.OF) and scale (T.SL). A reasonable adjustment presumes
reliable references (e.g. ice water, controlled precision water bath, etc.).
If the inputs are adjusted (i.e. offset and scale are different from factory settings) the device will shortly
display “T.OF“/ “T.SL“ after turned on.
Default setting for offset and scale are “OFF“= 0.00, i.e. inputs are not changed.
Zero point correction:
Displayed value = measured value –“ T.OF”
Zero point and slope correction:
Displayed value = (measured value - T.OF) •(1 + T.SL / 100)
Displayed value °F = (measured value °F - 32°F - T.OF) •(1 + T.SL / 100)
Example: Before starting the measurement, the values for “T.OF”and “T.SL”are set to “0.00 (OFF)” – “°[“ is
selected for the parameter “UN,T”. For reference in a water bath, a clinical thermometer is
used.
Display value in ice water (given value offset = 0.0 °C):
Display val. offset = -0.2 °C
Display value in water bath (given value slope = 37.0 °C):
Display val. slope = 36.6 °C
Calculation: T.OF= display value offset - given value offset= -0.2 °C –0.0 °C = -0.2 °C
T.SL = (given value slope / (display val. slope - T.OF) - 1) * 100
= (37.0 °C / (36.6 °C - (-0.2)) - 1) * 100 ≈0.54 (rounded)

9 Accuracy check / adjustment service
You can send the device to the manufacturer for adjustment and inspection.
Calibration certificate - DKD certificate - official certifications:
If the measuring instrument is supposed to receive a calibration certificate, it has to be sent to the
manufacturer (declare test points, e. g. –20 °C; 0°C; 70°C).
If the device is certificated together with a suitable sensor very high overall accuracies are possible.
Basic settings can only be checked and –if necessary –corrected by the manufacturer.
A calibration protocol is enclosed to the device ex works. This documents the precision reached by the
production process.
10 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.
Before changing batteries, please read the following instruction and follow it step by step.
Not following the instruction may cause harm to the instrument or the protection against
ingress of water and dust may be lost! Avoid unnecessary opening of the instrument!
Unnecessary disassembly puts the device at risk, i.e. the water tightness of the device,
and should be avoided.
Do not use different types or batteries with different state of charge. We recommend using
new and high quality alkaline batteries.
10.1 Required tools: 1x Phillips screwdriver PH 1
1) Unscrew the two screws (a) and remove the cover (b).
2) Exchange the two batteries (type: AA) (c) carefully. Ensure correct
polarity –the correct position of the batteries is drafted on the circuit
board. The batteries must slide in without force.
3) Check: O-ring seal (d) undamaged, clean and in the intended cavity? To
make the assembly easier and prevent damage, a dry O-ring can be
greased with suitable grease.
4) Put on the cover (b) straight. The device is starting automatically.
Note: the O-ring (d) has to been in the cavity, when pushing on the
cover (b)
5) Tighten the screws (a).
