IP Protection Rating
– CAISL models are rated to IP44 (with
option L1: IP65)
– CAIS models are rated to IP69K.
– The IP65/IP69K protection rating is
ensured only if the rubber gasket is
installed and all connections are
fastened securely (including the caps
on unused sockets).
Weighing platforms must be installed
and tested by a certified technician.
– If you install an interface port or
battery connection after setting up
your indicator, keep the protective
cap in a safe place for future use.
The cap protects the interface
connector from vapors, moisture
and dust or dirt.

Configuring Weighing Platforms
Analog/Digital Converter (ADC)
Purpose
Adjust the parameters of the analog/digital converter to the connected load cell or weighing
platform. After ADC configuration, the ADC in connection with the load sensor is defined as
a scale.
3
Once the ADC configuration has been locked, the indicator can no longer be used to
influence weighing results. The scope of functions available in the weighing instrument is
defined by the A/D converter. Weighing functions that can be activated include reading
weight values, taring, adjustment, reading the tare value, saving/deleting the tare entry.
Setup information
– ADC configuration is only possible when the menu access switch is open. Re-close the menu
access switch after ADC configuration.
– Before ADC configuration, you must first set whether or not the weighing platform will be
used as a standard or verifiable weighing platform.
– ADC configuration is carried out in the Service mode in the Setup menu under “
WP 1" for
the first weighing platform and “
WP 2" for the second.
– Entries made in ADC configuration will not be affected by a menu reset (returning the setup
parameters to their factory settings).
See also the overview in the “Setup Menu for A/D Converter Configuration" section.
Setting Parameters for ADC Configuration
Standard or Verifiable Configurations
In ADC configuration, you must first select whether the weighing platform should be
configured as a standard or verifiable (for use in legal metrology) weighing platform.
– Standard configuration “
Standard"
– Verifiable configuration “
Verifiable"
Select using the “
Q"or “q" soft key. Press the “O" soft key to confirm the setting and open
the Configuration menu.
Accuracy class
This menu item is not shown when the Standard configuration is active. When the Verifiable
configuration is active (for weighing platforms verified or verifiable for use in legal
metrology), only Class l/m can be selected. Activate the “
Accuracy class"
menu item, select “
Class III/IIII" and confirm your selection using the “l"
soft key.
Ranges
The capacity of the weighing platform can be divided into multiple ranges:
–“
Single-range mode":
The entire weighing range is divided into scale intervals on the basis of the lowest interval d
and the maximum load.
–“
Multi-interval mode":
The “Multi-interval mode” function divides the weighing capacity into as many as four
ranges, each with a different readability. Corresponding changes take place automatically.
Once the scale has been tared, the highest possible resolution is available even if the
weighing platform is loaded with a higher weight. This is only permitted in the accuracy
classes l/m for the verifiable configuration.
–“
Multiple-range mode":
Multiple-range mode has two or three weighing ranges. When the range limit is exceeded,
the scale switches into the next highest weighing range (lower resolution) and remains there.
The scale can be returned to the lower weighing range (higher resolution) only by pressing
the ( key and then unloading the scale.
Select the desired configuration using the “
Q" or “q" soft key. Confirm your selection using
the “
O" key. Make additional settings in the submenu: scale interval d/verification scale
interval e, minimum load (Verifiable configuration only), range limits (Multi-interval or
Multiple range mode only) and maximum capacity. Confirm using the “l" soft key or cancel
using “
Esc."
Scale interval d
Scale interval d indicates the resolution of the weighing instrument.
The scale interval d can be entered only in increments of 1, 2, 5, 10, 20, etc.
When using verifiable or verified weighing platforms, the scale interval d is the same as
the verification scale interval e.
Verification scale interval e
The verification scale interval e indicates the resolution of the weighing instrument in
legal metrology. The verification scale interval e can be entered only in increments of 1, 2,
5, 10, 20, etc. For weighing instruments of accuracy class l or m, e = d. This is why
the scale interval d does not need to be entered separately.
When “Standard configuration” is used, this menu item is not displayed.
Minimum capacity (min. cap.)
When “Standard configuration” is used, this menu item is not displayed. The minimum
load of the connected weighing platform is entered under this menu item.
The minimum load for scales of accuracy class l is 20 e and 10 e for class m.
Important Note: The function of the minimum load setting is to warn operators that
below this limit, the summation of tolerances might lead to significant measurement
errors. In Germany, for example, initial weights below the minimum load are not allowed.
Maximum capacity (Max. cap.)
The maximum capacity is the maximum load that may be placed on the weighing
instrument. When heavier weights are used the weighing instrument displays overload
“H.” The scale intervals of the weighing instrument are calculated using the maximum
load and the scale interval d (e.g. max. capacity = 15.000 kg, smallest scale interval
d = 0.005 kg yields 3000 scale intervals).
In legal metrology the total number of intervals must be no more than 3000 e, and when
using multi-interval scales there must not be more than 3000 e intervals per range.
In standard operation, as opposed to legal metrology, you can define a “Super Range”
weighing instrument of over 3000 intervals. These parameters, however, may be
influenced by physical restrictions.
Range 1, Range 2, Range 3
The range limits are entered for the individual ranges. The accuracy changes when these
limits are exceeded. The following applies when entering limits: range 1 < range 2
< range 3 < maximum capacity.
This means that the weighing range can be divided into a maximum of 4 ranges. The
resolution changes at intervals of 1, 2, 5, 10, 20 etc., where the lowest resolution is the
smallest scale interval entered. Set ranges that are not required for use to zero.
Available units
With this function, you can make particular weight units (weight unit x, x=1, 2)
inaccessible during weighing. Available units are indicated by a * on the display (more
than one can be selected).
To enable or disable a unit, select the unit by pressing the “
Q" or “q" soft key, and then
press the “l" soft key (toggle function).
Saving parameters
To save the ADC configuration, use the “
O" soft key to select “Yes" and confirm with
the “l" soft key. The device software is reset, and the scale returns to the normal
weighing mode. To exit the menu without saving configuration changes, press the “
o"
soft key.
Once these parameters have been configured, the A/D converter in conjunction with the
load cell(s) is defined as a weighing instrument. The A/D converter, in conjunction with
the weighing platform, can now be used like any standard weighing platform. In addition,
the weight unit must be defined and the weighing platform adjusted (calibration,
adjustment and linearization must be performed). For a detailed description of these
procedures, see the “Adjustment in Service Mode" section.

Entering geographical data allows the external adjustment of weighing equipment at a place
(e.g. at the manufacturer or vendor's place of business) that is not the same as the place of
installation. If the weighing equipment is adjusted at the place of installation, it is not
necessary to enter geographical data.
The sensitivity of weighing equipment changes depending on the place of installation as
it is dependent on the on-site gravitational force – or, more precisely, on gravitational
acceleration. Saving geographical data makes it possible to change the place of installation
of the weighing equipment after external adjustment has been carried out.
The adjustment of weighing equipment is valid at the place of installation and within a
specific tolerance zone. At 3000 e this zone extends ±100 km from the set geographical
latitude and ±200 m from the set elevation above sea level.
Installation Location in Germany
An exception to this is the setting for “Germany (Zone D):” If during external adjustment of
weighing equipment within Germany the geographical data
– Geographical latitude: 51.00 degrees
– 513 m elevation above sea level
are entered, the weighing equipment can be used throughout Germany. Gravitational
acceleration for “Germany (Zone D)” is 9.810 m/s
2
. On delivery the geographical data for
“Germany (Zone D)” are entered in the output device.
It is recommended to use the geographical data settings for “Germany (Zone D)” when
adjusting and delivering the weighing equipment within Germany.
Entering exact geographical data will lead to a higher level of accuracy but will also restrict
the tolerance zone.
Setup information
– It is only possible to enter geographical data when the menu access switch is open.
– When the Service mode is active, geographical data can be entered in the Setup menu under
“
WP 1" for the first weighing platform and “WP 2" for the second. Settings are made in
the “
Calibration/adjustment: Geographical data: Input
parameters" menu.
– You can enter either the “
latitude" (geographical latitude in degrees) and
“
altitude" (elevation in m above sea level) or the value for gravitational acceleration
“
gravity"
Gravitational acceleration takes precedence over the geographical latitude and elevation of
the location: If it has been entered, input fields for latitude and elevation show the values
“
99999.99" and “9999999" respectively. If only elevation and latitude have been
entered, “
0000000" is displayed for gravitational acceleration.
h
Then make sure that the geographical data for the adjustment location has been entered
correctly. If no external adjustment is carried out, enter the data for the installation location.
The data can be obtained from the relevant land registry or Ordnance Survey.
Procedure
t Remove the cap.
t Slide the menu access switch to the left (= “open" position).
If the device is part of a verified weighing facility, this will only be possible if the
verification seal is broken. The weighing equipment must then be verified again.
t Activate the Service mode, see “Service Mode."
t Select weighing platform “WP 1" in the “Device Parameters" menu item.
t If the “Internal" setting is not already activated (marked by “o"), select the setting
using the “
Q" or “q" soft key and confirm with “O."
y The menu for the “WP-1 INTERNAL" device parameters is displayed.
t Use the “Q" or “q" soft key to select and open the
“
Calibration/adjustment" menu using “O."
t Use the “Q" or “q" soft key to select and use “O" to open the “Geographical
data" menu.
t Use the “O" soft key to confirm “Input parameters."
Entering Geographical Latitude and Elevation
t Use the “Q" or “q" soft key to select the corresponding input field.
t Enter the number via the keypad and confirm using the “l" soft key.
y The next input field is selected.
In this example, the geographical data are entered for the respective platform as a value
pair “Latitude" and “Altitude." After this data was saved and the scale
returned to weighing mode, this pair of values is displayed again the next time the
display menu is opened. The input field for gravitational acceleration is empty.
In this example, the value for gravitational acceleration is entered for the place of
installation. The fields “
Latitude" and “Altitude" are invalid. The set value is
then re-displayed after it is saved and the input menu is re-opened. If you exit the Setup
menu and then open the Service mode, the set value for gravity is no longer displayed.

via the keypad and confirm using the “l" soft key.
Permissible value range:
9.700000 d < gravity 2 d < 9.900000
In the example shown here, the value for gravity has been changed.
The new value,
9.810000 m/s2 applies to the setting “Germany (Zone D).”
t Press the “o" soft key to exit the Input menu.
t Use the “Q" soft key to select the “Save parameters" menu item.
t Use the “Q" soft key to select “Yes" and use the “l" soft key to confirm.
y The message “Data stored" appears briefly.
The program then returns to the “
No" display status.
t Press M or “oo" to exit the Setup menu.
t Slide the menu access switch to the right (= “closed" position) and reattach the cap.
y The display goes out and the device restarts. Then weighing mode is active.
