Formula Zero point correction:
Displayed value = measured value – T.OF
Gradient correction °C:
Display = (measured value – T.OF) * (1 + T.SL / 100)
Gradient correction °F:
Display = (measured value – 32 °F – T.OF) * (1 + T.SL / 100) + 32 °F
Example calculation – Zero point correction T.OF to 0.00
– Gradient correction T.SL to 0.00
– Display unit UNIT to °C
– Display in ice water -0.2 °C
– Display in ice water setpoint T.OF = 0.0 °C

6 | Bases for measurement G 1730
16 / 25 B-H86.0.0D.DB2-1.0
6 Bases for measurement
6.1 Possible measuring errors
6.1.1 Immersion depth
Liquids Immerse to a depth of at least 20 mm and then stir. Otherwise, measuring errors can
occur due to the heat transmission of the sensor tube if the immersion depth is too
shallow.
Gases Immerse as far as possible into the gas to be measured so that the measuring sensor
is subjected to a heavy flow.
6.1.2 Surface effects and poor heat transfer
Surface temperature Special measuring sensors are required for this purpose. Surface characteristics,
design of the measuring sensor, heat transfer and environmental temperature influ-
ence the measurement result.
NOTE
Thermally conductive paste between the measuring sensor and surface can also in-
crease measurement accuracy in some cases.
6.1.3 Cooling / evaporation
Air temperature The measuring sensor should be dry; otherwise the temperature measurement is too
low.
6.1.4 Response time
Response time T90 An adequate wait time must be observed for the measuring process before reading
the measured value. The response time T90 describes the time in which the displayed
measured value reached 90% of the end value. See Technical data [}p.22].
6.1.5 Limit values
Temperature range
CAUTION
Destruction of the measuring sensor!
When conducting measurements in media with high or very low temperatures, there is
a risk that the measuring sensor is not designed for such extremes.
– The limit values must be observed!

7 Maintenance
7.1 Operating and maintenance notices
NOTE
The product and temperature probe must be handled with care and used in accord-
ance with the technical data. Do not throw or strike.
NOTE
If the product is stored at a temperature above 50 °C, or is not used for an extended
period of time, the batteries must be removed. Leaks from the batteries are avoided as
a result.
7.2 Battery
7.2.1 Battery indicator
If the empty frame in the battery display blinks, the batteries are depleted and must be
replaced. However, the device will still operate for a certain length of time.
If the BAT display text appears in the main display, the battery voltage is no longer ad-
equate for operation of the product. Now the battery is fully depleted.
7.2.2 Changing battery
DANGER
Danger of explosion!
Using damaged or unsuitable batteries can generate heat, which can cause the batter-
ies to crack and possibly explode!
– Only use high-quality and suitable alkaline batteries!
CAUTION
Damage!
If the batteries have different charge levels, leaks and thus damage to the product can
occur.
– Use new, high-quality batteries!
– Do not use different types of batteries!
– Remove depleted batteries and dispose of them at a suitable collection point!
NOTE
Unnecessary screwing places the water-tightness of the product, among other things,
at risk and should be avoided.

7 | Maintenance G 1730
18 / 25 B-H86.0.0D.DB2-1.0
NOTE
Read the following handling instructions before replacing batteries and follow them
step by step. If disregarded, the product could be damaged or the protection from
moisture could be diminished.
Description Proceed as follows to replace the batteries.
Prerequisites – The product is switched off.
– A suitable PH1 is available
Instruction 1. Unscrews the Phillips screws and remove the cover.
2. Carefully replace the two Mignon AA batteries. Ensure that the polarity is correct!
It must be possible to insert the batteries in the correct position without using
force.
3. The O-ring must be undamaged, clean and positioned at the intended depth. In or-
der to facilitate assembly and avoid damage, a suitable grease can be applied.
4. Fit the cover on evenly. The O-ring must remain at the intended depth!
5. Tighten the Phillips screws.
Outcome of an action The product is now ready for use again.
7.3 Calibration and adjustment service
7.3.1 Certificates
The certificates are categorised as ISO calibration certificates and DAkkS calibration
certificates. The purpose of the calibration is to verify the precision of the measuring
device by comparing it with a traceable reference.
NOTE
The ISO standard 9001 is applied for the calibration certificates. These certificates
area affordable alternative to the DAkkS calibration certificates and provide informa-
tion of the traceable reference, a list of individual values and documentation.
NOTE
The DAkkS calibration is based on DIN EN ISO/17025, the accreditation basis recog-
nised worldwide. These certificates offer high-quality calibration and consistently high
quality. DAkkS calibration certificates can only be issued by accredited calibration
laboratories which have demonstrated their expertise in accordance with DIN EN ISO/
IEC 17025. The ISO calibration includes any necessary adjustment with the purpose
of minimising a deviation of the measuring device.
DAkkS calibration certificates are accompanied with a list of individual measurements
before and after the adjustment, documentation and, if applicable, graphic representa-
tion, calculation of the expanded measuring uncertainty and traceability to the national
standard.
