§ Close the Midrics indicator:

Re-attach the front panel and secure it with the 4 cap nuts

Establishing a Connection to the Power Supply

§ Check the voltage rating and plug design.

$ Power is supplied via the installed power cord that is supplied. The power supply is inte-

grated into the indicator. The device can be operated with a voltage of 100 V to 240 V. The printed voltage rating (see type label) must match the voltage in the place of installation. If the stated supply voltage or the plug design of the power cord does not comply with the standard you use, please inform your nearest Sartorius representative or your dealer. The power connection must be made in accordance with the regulations applicable in your country.

Connecting the device, rated to Class 1, to power supply (mains supply): The device must be plugged into a properly installed wall outlet which has a protective grounding conductor (PE). The power plug or a different, suitable disconnecting device for the power must be easily accessible.

Safety Measures

If you use an electrical outlet that does not have a protective grounding conductor, ensure that an equivalent protective conductor is installed by a certified electrician (as specified in the applicable regulations for installation in your country). The protective effect must not be negated by using an extension cord without a protective grounding conductor.

Warm-up Time

To return precise results, the device must warm up for at least 30 minutes after initial connection to the power supply. Only after this time will the device have reached the required operating temperature.

Using a verified device in legal metrology:

$ Ensure that there is a warm-up time of at least 6 hours after initial connection to the

power supply.

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 is defined as a scale in connection with the load sensor.

Set-up Information

– ADC configuration is only possible

when the menu access switch is open. Close the menu access switch after ADC configuration, as otherwise there will not be any display of the conditions “overload” (“H”) and “underload” (“L”).

– When the service mode is active, the

ADC configuration takes place in the Setup menu under “WP-1” under the menu item ADC-CON.

– Enter the maximum capacities in a suit-

able weight unit, without any decimal places (decimal places will be truncated by the rounding function).

!If you return to the highest level of the

menu without saving the configuration parameter beforehand (menu item save) any settings that have been made will be deleted.

– Entries made in the ADC configuration

will not be affected by a menu reset (returning the set-up parameters to their factory settings).

!Note:

Once the A/D converter 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, calibration, reading the tare value, saving/deleting the tare entry

Description of the Individual Menu

Items for the A/C Converter

Configuration

Standard or verifiable configuration

(menu items STAND. / VERIF.)

In ADC configuration it is first selected,

whether the weighing platform should

be configured as a standard or verifi-

able (for use in legal metrology) weigh-

ing platform. – Standard configuration (STAND.) – Verifiable configuration (VERIF.).

Accuracy Class (menu item CLASS)

Only displayed in verifiable configura-

tion.

Only menu items 3/4 (accuracy class

l/m) can be selected. If the menu item is

not already marked as being active with

a circle (o), the ) key must be pressed

once to activate it.

Range Selection (menu item RANGES)

Depending on the setting under this

menu item, the menu points RANGE 1,

RANGE 2 and RANGE 3 will either be

displayed or will not be displayed for

further configurations. – Single range mode (SINGLE)

The entire weighing capacity is divided

into decimal numbers dependent on the

smallest scale interval d and the maxi-

mum weight. The readability corre-

sponds to the scale interval d. – Multi-interval scale (MULT.INT.)

The function “multi-interval scale”

divides the weighing capacity into a

maximum of three intervals with differ-

ing readability. The corresponding

change takes place automatically at the

defined interval limits. After taring, the

best possible resolution (smallest scale

intervals) is available even when there is

a load on the weighing platform. – Multiple range mode (MULT.R.)

A multiple-range scale has two or three

weighing ranges. When the range limit

for the lower weighing range is exceed-

ed, the scale switches into the next

highest weighing range (lower resolu-

tion). The scale only switches back to

the higher resolution when the weigh-

ing platform has been completely

unloaded.

Scale Interval d

The scale interval d indicates the resolution of the weighing instrument. The scale interval can only be entered in increments of 1, 2, 5, 10, 20, etc. When “verifiable configuration” is used, this menu item is not displayed. When using verifiable or verified weighing platforms (classes l and m), 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 scale interval can only be entered in increments of 1, 2, 5, 10, 20, etc. When “standard configuration” is used, this menu item is not displayed.

Maximum Capacity (max. cap.)

The maximum capacity is the maximum load that may be placed on the weighing platform. When heavier weights are used the weighing instrument displays overload “H”. The scale intervals of the weighing instrument are calculated using the maximum capacity and the scale interval d (e.g. max. capacity = 15.000 kg, smallest scale interval = 0.005 kg yields 3000 scale intervals). In legal metrology the total number of intervals must be no more than 3125 e, and when using multi-interval scales there must not be more than 3125 e intervals per range.

Range 1, Range 2, Range 3 (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 < Max. cap. 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 weighing units (menu item UNITS)

This menu item is used to select the weighing units that have been cleared for use in weighing. All units marked with a circle (o) have been cleared for use, multiple selection is possible. If you need to use this indicator as a legal measuring instrument (legal for trade), be sure you have selected a permissible unit.

Save parameters (menu item SAVE)

The ADC configuration data is saved once at the end of defining the settings using the SAVE function.

Testing and configuration for operation in legal metrology

A metrology plate is included in the scope of supply of the indicator. Once ADC configuration is complete, record the metrological data for all ranges on the metrology plate. Attach the plate underneath the display and cover with the supplied waterproof foil.

Under menu item 1.7, check that only authorized weight units can be selected.

Entering Geographical Data

Purpose

Entering geographical data allows the external calibration 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 calibrated 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 calibration 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.

An exception to this is the setting for “Germany (Zone D)”: If during external calibration of weighing equipment within Germany the

geographical data – 51.00° geographical latitude – 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?.

On delivery the geographical data for

“Germany (Zone D)” are entered in the

output device.

It is recommended to use the geograph-

ical data settings for “Germany (Zone

D)” when calibrating 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.

Set-up Information

– It is only possible to enter geographical

data when the menu access switch is open.

– Geographical data can be entered when

the service mode in the Setup menu for “WP 1” is activated. The settings are made in the corresponding Setup menu under menu item 1.20.

– Either the geographical latitude in

degrees (menu item 1.20.1) and elevation in m above sea level (menu item

1.20.2), or the value for gravitational acceleration (menu item 1.20.3) can be entered. 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.

! If you return to the highest level of

the Setup menu without saving the configuration parameter beforehand (menu item 1.20.4) any settings that have been made will be deleted.

Procedure

– Open the menu access switch. 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. – Activating the service mode – Select the weighing platform – Enter the geographical data for the

place of calibration under menu items

1.20.1 to 1.20.3 and save them under

menu item 1.20.4. The data can be

obtained from the relevant land registry

or Ordnance Survey. – Carry out external calibration

(see page 20) – After the calibration, enter the geo-

graphical data for the place of installa-

tion under menu items 1.20.1 to 1.20.3

and save them under menu item 1.20.4. – Close the menu access switch. – The weighing equipment can now be

operated at the place of installation,

and within the abovementioned toler-

ance zone.

Note: The set geographical values are displayed during the calibration procedure if the display of the data has been activated in the Setup menu under “utilit” menu item 8.12.2 (factory setting: 8.12.1, display deactivated). When the display of the geographical data is activated the calibration procedure is as follows: If the elevation and geographical latitude are used, after the start of the calibration procedure “CAL” the word “ALTITUDE” will appear briefly followed by the set elevation (in meters above sea level). The display is confirmed using the ) key (and cancelled using the ( key). Then, the word “LATITUDE” will be displayed briefly, followed by the set geographical latitude in degrees. This can also be confirmed using the ) key (and cancelled using the ( key). After this, you will be prompted to place the calibration weight on the platform. If gravitational acceleration has been entered instead of elevation and geographical latitude, the word “GRAVITY” will appear briefly, followed by the set value for gravitational acceleration. The display is confirmed using the ) key (and cancelled using the ( key).

Calibration, Adjustment

Purpose

The accuracy of the measurement results must be checked. This is carried out using calibration and adjustment.

Perform calibration to determine the difference between the value displayed and the actual weight on the platform. Calibration does not entail making any changes within the weighing equipment.

During adjustment, the difference between the measured value displayed and the true weight of a sample is corrected, or is reduced to an allowable level within maximum permissible error limits.

Features

The configured weighing platform determines which of the following features are available:

– External adjustment with the weight

of the factory setting – standard weight (1.9.1), not for use in verified weighing instruments

– External calibration with a user-defined

weight (1.9.3), not for use in verified weighing instruments

– Block the key ) –> 2 sec to prevent

use of the functions described above (1.9.10):

– Calibration with automatic adjustment

(1.10.1), not for use in verified weighing instruments

– Calibration with the option of activat-

ing the adjustment function manually (1.10.2)

– Adjustment prompt – flashing W sym-

bol (1.15.2).

– Block external adjustment (1.16.2)

– Display of elevation and geographical

latitude, or gravitational acceleration

after CAL has been displayed at the

start of the calibration procedure (menu

item 8.12.2). These values will only be

displayed if they have been entered and

activated in the service menu.

For each of the parameters elevation,

geographical latitude and gravitational

acceleration, the term is displayed first

(Altitude, Latitude or Gravity) for 1 sec-

ond, and then the corresponding value

is displayed continuously until you

press the ) key.

Note

When using verified weighing instru-

ments, the external calibration function

can only be used when the menu access

switch is open once the verification seal

has been broken. The device must then

be verified again.
