4.2 Adjustment of the measuring input
The temperature input can be adjusted with the zero point correction and the gradient
correction. If an adjustment is made, you change the pre-adjusted factory settings.
This is signalled with the display text T.OF or T.SL when switching on.
1. Switch the device off.
2. Hold the down button and press the On/Off button briefly to switch on the device
and open the Adjustment menu.
3. The display shows the first parameter. Release the down button.

Formula used by device:
Temperature = °C: Display = (measured value - T.OF) * (1 + T.SL / 100)
Temperature = °F: Display = (meas. value - 32 °F - T.OF) * (1 + T.SL / 100) + 32 °F
Adjustment example:
Temperature unit= °C, the adjustment is carried out in 2 separate steps at 0 °C (e.g. ice
water) and at a reference temperature (e.g. clinical thermometer with water bath 37 °C).- First
set the values of t.oF and t.SL in the adjustment menu to 0
Zero point: - Set the temperature probe to 0 °C and let it adjust.
- Start the adjustment menu and enter the display value at 0 °C for t.oF
- After leaving the menu, the device should now display 0.0 °C.
Slope: - Set the temperature sensor to the reference temperature and let it adjust.
- Calculate slope correction:   󰇡

G 1700 series 5 | Measurement Basics
B-H86.0.0X.DK2-3.1 13 / 20
5 Measurement Basics
5.1 Sensor/device accuracy
The device can be equipped with different interchangeable sensors. The temperature
sensors are divided into the following classes according to EN 60751.
class
deviation
temperature range
B
±0,3 °C ±0,5 % of measured value
-50 … +500 °C
A
±0,15 °C ±0,2 % of measured value
-30 … +300 °C
AA = 1/3 DIN B
±0,1 °C ±0,17 % of measured value
0 … +150 °C
In order to achieve high exchange accuracy without the necessity of an additional
correction, we recommend using class A or AA temperature sensors.
5.2 Possible measuring errors
5.2.1 Immersion depth
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.
Gas: Immerse as far as possible into the gas to be measured so that the measur-
ing sensor is subjected to a heavy flow.
5.2.2 Surface effects and poor heat transfer
Special measuring sensors are required for this purpose. Surface characteristics, de-
sign of the measuring sensor, heat transfer and environmental temperature influence
the measurement result.
NOTE: Thermally conductive paste between the measuring sensor and surface can
also in-crease measurement accuracy in some cases.
5.2.3 Cooling / evaporation
When measuring the air temperature, the probe should be dry, otherwise the tempera-
ture measured will be too low.
5.2.4 Response time
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.

6 Operation and maintenance
6.1 Operating and maintenance notices
_
NOTE
The device and temperature probe must be handled with care and used in accordance
with the technical data. Do not throw or strike.
_
NOTE
Plugs and sockets must be protected from soiling.
_
NOTE
If the device 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.
6.2 Battery
6.2.1 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
adequate for operation of the device. The battery is fully depleted.
6.2.2 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!
_

G 1700 series 6 | Operation and maintenance
B-H86.0.0X.DK2-3.1 15 / 20
CAUTION
Damage!
If the batteries have different charge levels, leaks and thus damage to the device can
occur.
–Only use high-quality and suitable alkaline batteries!
–Do not use different types of batteries!
–Remove depleted batteries immediately and dispose of them at a suitable collec-
tion point.
_
NOTE
Unnecessary unscrewing endangers the protection against moisture and should
therefore be avoided.
NOTE
Read the following handling instructions before replacing batteries and follow them
step by step.
If disregarded, the device could be damaged or the protection from moisture could be
diminished.
1. Unscrews the Phillips screws (A)and remove the cover.
2. Carefully replace the two Mignon AA batteries (B). En-
sure that the polarity is correct! It must be possible to in-
sert the batteries in the correct position without using
force.
3. The O-ring (C) must be undamaged, clean and posi-
tioned at the intended depth.
4. Fit the cover (D) on evenly. The O-ring must remain at
the intended depth!
5. Tighten the Phillips screws (A).

10.2 Calibration and adjustment service
The purpose of the calibration is to verify the precision of the measuring device by
comparing it with a traceable reference.
Both ISO calibration certificates and DAkkS calibration certificates are available from
Greisinger.
_
Explanation
The ISO standard 9001 is applied for the iso-calibration certificates.
These certificates area affordable alternative to the DAkkS calibration certificates and
provide information of the traceable reference, a list of individual values and documen-
tation.
The DAkkS calibration is based on DIN EN ISO/17025, the accreditation basis is
recognised worldwide. These certificates offer high-quality calibration and consistently
high quality. The DAkkS calibration includes any necessary adjustment with the pur-
pose of minimising a deviation of the measuring device.
_
NOTE
The device is delivered with a test report.
This confirms that the measuring device has been adjusted and tested, without making
any statement about the accuracy of a temperature sensor.
_
NOTE
Only the manufacturer can check the basic settings and make corrections if necessary.
