3.1.1 Mounting the clamping element
There are two options how to connect the device to the process:
Figure 1: mounting options: a) clamping block, b) clamping shoe
3.1.1.1 Mounting the clamping block
Required tools:
Hexagon socket wrench 3 mm (mounting screws)
Hexagon socket wrench 2 mm (vibration protection)
Turn back the vibration protection, so that it
does not exceed the semi-cycle groove for the
pipe (see picture to the right).
Mount the clamping block with the included
screws at the intended position on the pipe. Do
not exceed the allowed tightening torque of 2
Nm for pipe diameters up to 17,2 mm and 4
Nm for bigger pipes.
Hand-tighten the vibration protection. Do not
tighten the vibration protection screw too hard.
You might damage the clamping block or the
pipe.
Figure 2: Clamping block from below
3.1.1.2 Mounting the clamping shoe
Required tools:
depends on the used hose clamps
Mount the clamping shoe with two appropriate hose clamps or tightening straps.
The maximum width for a safe fit is 5 mm.
Tighten the clamps so that the clamping shoe cannot be moved by hand applying a
usual hand force.

Page 4/20
3.1.2 Mounting the measuring insert
The mounting procedure for the measuring insert is identical for all clamping elements.
First apply heat conductive paste to the tip of the measuring insert. Heat conductive paste
is mandatory for this type series for a good measuring accuracy.
Now insert the measuring insert into the bore in the clamping element. You can position
the insert in two ways. Choose the position that simplifies the later cable routing.
Finally tighten the connection by turning the screw connection (see figure 3). No tools are
required for this step. Never try to turn the housing, if you have a device with field housing
or integrated transmitter. You might destroy the device by this.
Do not turn or move the clamping element with a mounted measuring insert. You might
damage or destroy the insert.
Figure 3: Mounting steps for the measuring insert
3.2 Mount / Dismount Display
In order to dismount the display, turn off the device cover and pull out the display. The
three small studs at the outer diameter of the display (all 120°) facilitate removal.
The display cable can be disconnected either at the display or at the clamp module. When
reconnecting the cable, please take polarity (red lead) into account. Otherwise the cable
will not fit into the plug.
When mounting the display, you can choose its orientation. Complete the process by firmly
reattaching the cover.

4.1 Calibration
We recommend an annual recalibration.
Uninstall only the measuring insert. This way the measuring position remains unchanged
as it is defined by the clamping element.
Apply new heat conductive paste when you reinstall the measuring insert after the calibra-
tion. This ensures a good and constant thermal coupling between insert and pipe.
For further details please consult the separate calibration guideline for the Clamp-on family
(TA_008).
4.2 Maintenance / Service
When properly installed in accordance with applicable specifications, this device is
maintenance-free. However, we recommend an annual recalibration of the device.

When entering parameters, either numerical inputs or a selection lists with fixed options is
available.
In general, the actual selection will be displayed first (view mode). Press OK to switch to
edit mode to change the parameter. After this is done, the display will then switch back to
view mode so that you can check the new setting.
6.3.1.1 Selection of a value from a selection list
Up to four options are shown at the same time in one selection list. When the selection list
is longer, a scroll bar on the left side of the display indicates the position of the selected
item in the selection list.
When you press the ESC button, you cancel the entry and go back to view mode. The se-
lected value is not saved.
With the OK button, the selected value is saved. Saving the value is confirmed with an in-
formation window and the new value is shown in view mode.
With ESC, you leave the view mode and return to the menue.

6.3.2 Setting a numeric value
When setting numeric values, the screen shows the following elements (from top to bot-
tom):
Designation of the parameter that can be set (in header)
Help text (if applicable)
Numeric value and unit
Function of buttons (if applicable)
After selecting a menue item for numerical entry (e.g. Upper range value), at first the value
is displayed only. The numeric value itself is shown in square brackets and its unit behind
it or in the lower right area. Unused leading digits are marked with bottom lines. You need
to press OK again to enter the edit mode.

BA_084_2019-05_10.00 Temperature transmitter clamp-on
Page 13/20
Numeric values are entered digit by digit. First, always the leftmost digit is selected (visible
with a triangle above and below the number). By pressing OK, you go to the next digit.
Figure 9: Elements when setting a numeric value
You change the selected digit by pressing the or button. The higher value digit is
also increased or decreased when passing zero. For instance, you can easily go from 100
to 90 without having to edit two digits.
Lower value digits are not influenced, unless the parameter limit is reached. The value is
then set to the parameter limit.
You can set negative numbers by decreasing the value below zero.
When you press the ESC button, you can cancel the entry at any time and return to the
display of the set value. Any change of the value is not saved.
With the OK button you confirm the set digit value and jump to the next digit.
When you confirm the rightmost digit, the entire value is saved. You can save the new val-
ue from any digit by pressing and holding the OK button.

Table 8: "Adjustment" menue

BA_084_2019-05_10.00 Temperature transmitter clamp-on
Page 15/20
6.4.3.1 Upper and lower adjustment
The lower adjustment results in an offset of the characteristic curve. It thus affects the
measuring range.
The upper adjustment changes the slope of the characteristic curve by correcting the span
of the measuring range.
Execute the lower adjustment prior to the upper adjustment for a correct full adjustment.
Figure 11: Effect of the upper and lower adjustment on the characteristic curve
You can perform the upper and lower adjustment at any reference temperature level. For
instance, you can perform the lower adjustment of a -40…150 °C device at 0 °C. The ref-
erence temperature level for the upper offset can also be freely chosen. To ensure that the
adjustment is as precise as possible, the upper and lower adjustment should be performed
as close as possible to the lower range value and upper range value of the measurement
ranges.
6.4.3.2 Current adjustment
You can use the current adjustment, if the reading at the end of the measurement chain
(re-converted current value) does not correspond to the measured pressure. With this
function you can compensate deviations in the output stage as well as the downstream
measurement chain.
Proceed as follows (example for 4 mA):
Select function "Current adjust." –> "Adjust. 4 mA"
Use "OK" to activate constant current mode (4 mA). CAUTION! The output current
value now no longer corresponds with the measured value! This is indicated by the
icon "Function check" (see 6.2.3).
Read the displayed current value at the end of the measurement chain.
Enter this current value (e.g. 3.996) at the device. The device now corrects the cur-
rent output so that 4 mA are shown at the end of the measurement chain.
When leaving the function, the constant current mode is disabled and the current value
corresponds again to the measured value.

Maximum current
Limit of the upper output current (20…21 mA)
Table 11: "Measurement/Output" menue
Independent from the setting of the minimum and maximum current limit, the set measur-
ing range always corresponds to a current range of 4…20 mA.
6.4.5.1 Output function
You can set the output function proportionally rising to the measured value (selection "lin-
ear") or proportionally falling (selection "inverse").
6.4.5.2 Setting the measurement range
You can freely set the lower and upper range value within the nominal range of the device.
Please note that when the turndown is increased, the measurement error also increases. If
you use a very small range you must therefore accept a significant measurement error.
We recommended a maximum turndown of 10:1.
The lower range value must be below the upper range value. For an inverse characteristic
curve, select the output function setting “inverse”.
6.4.5.3 Minimum and maximum current
In the standard setting, the current output is limited at 3.8 and 20.5 mA, meaning a further
drop or rise in the measured variable does not change the current. You can freely select
these current limits for the lower limit between 3.8 and 4 mA and for the upper limit be-
tween 20 and 21 mA.
6.4.6 Menue "Diagnosis"
In this menue you can view and configure various diagnostic information. The following

6.4.8.1 HART address
This address corresponds with the short address which is used for the HART-
Communication. It can be set within a range of 0 to 63. Please note, that setting the short
address between 1 and 63 will not automatically activate the constant current mode. This
must be done under the menue “Current mode” (see 6.4.8.2).
6.4.8.2 Current mode
The current mode determines whether the output current of the device is set to respond
proportionally to the measured value (selection “proportional”) or whether it should remain
constant at 4 mA (selection “constant”). When the current mode “constant” is in use, the
measurement value can only be read using HART-commands (e.g. for HART-multidrop-
operation).
