1. Prior to operation
•Prior to using the instrument (commissioning / assembly) the
user is requested to thoroughly read the instruction manual and
comply with it in all points.
•Never take measurements on live parts.
•Please observe the measuring ranges of the different sensors
(Overheating may cause irrversible damage).
•Take care of storage and transport conditions (No direct
exposure to solar radiation).
•Temperature adjustments may only be carried out with proper
reference material.
•In case of use in changing locations with different climatical
conditions the instrument requires a recovery period of several
minutes.
•Technical data, storage and transport conditions can be found
on the technical data sheet.

Proper use:
•The instrument may only be used under the conditions defined
in the technical data sheet.
•The measuring instrument may only be used under those
conditions and for those purposes for which it was built.
•Operational safety can no longer be ensured when the
instrument is opened or modified.

4. Operating the instrument
In contrast to most traditional hand held instruments, the
THERMOPORT 20 do not have a key field but a
“THUMB-WHEEL” on their left side.
The wheel permits a 15º turn up and downwards and can additio-
nally be pressed in the central position.
Aturn upwards selects the upper menu whereas the lower menu for
configuration and adjustment is selected by turning the wheel
downwards.
For switching the instrument on and off or confirm the selection of
values the thumb wheel has to be pressed in the central position.

One point temperature calibration
CAL1: CAL1 (one point calibration) gives the user the possibility to
define an offset for temperature 1. The offset is displayed in the
lower part of the screen. Maximum offsets are:
PT100 channel: +/- 2.5°C/°F in 0.01°C/°F steps
TC channel: +/- 10°C/°F in 0.1°C/°F steps.
The offset will be valid over the complete measuring range.
Factory calibration can be obtained by setting the offset to 0.0.

page 33
Manual THERMOPORT 20 english
CAL2: CAL2 (one point calibration) gives the user the possibility to
set an offset for temperature 2. The offset is displayed on the upper
part of the screen.
The maximum offset on the TC channel is +/- 10°C/°F in 0,1°C/°F
step.
The offset is valid over the complete measuring range.
Factory calibration can be obtained by setting the offset to 0.0.
Important: Calibrations only make
sense if they are carried out by special-
ly skilled persons using appropriate
calibration equipment.

Calibration of the PT100 channel by means of coefficients
CAL1 LH: Every characteristic curve of a PT100 sensor can be
defined by a polynomial. Polynomials are used for minimizing errors
and non-linear behaviour of a sensor element.
For temperatures -200°C...0°C (-328...32°F) the characteristic of a
PT100 corresponds to the following polynomial:
Rt = R0 [1 + At + Bt² + C(t-100°C) t³]
For temperatures > 0°C the polynomial is:
Rt = R0 [1 + At + Bt²]
Rt is the resistance at temperature t, R0 resistance at temperature
0°C. A,B and C are coefficients of the polynomial equation.
In menu CAL1 LH these coefficients as well as the value R0 can
be set.
Important: the determination of the
coefficients A,B,C and R0 must only be
carried out by accredited laboratories.

7. Changing the battery
The letters "BAT" on the display indicate a remaining operating time
of a few hours. Open the battery case on the back of the instrument.
Remove the empty batteries and insert new ones.
Please use only batteries type IEC LR6 AA.
Do not use rechargeable batteries!
Reverse polarity may destroy the instrument. Make sure to place
the batteries in the correct position and to use high quality batteries
only.

8. Maintenance and adjustment
For use in climatological purposes we recommend a yearly
maintenance.
Before checking or adjusting the instrument it should be left in an
environment of 20ºC to 25ºC (68°F to 77°F) temperature for about 12
hours.
Recalibrations should recommendably be carried out only by skilled
persons or even better by accredited laboratories.
For cleansing the instrument use humid cloth. Do not use any
detergents but only clear water.
