1 Introduction Thank you for choosing a METTLER TOLEDO balance. The precision balances of the NewClassic line combine a large number of weighing possibilities with easy operation. These operating instructions apply to all balance models ML in the NewClassic line. However, the different models have different charcteristics regarding equipment and performance. Special notes in the text indicate where this makes a difference to operation. 1.
2 Safety Precautions Always operate and use your balance only in accordance with the instructions contained in this manual. The instructions for setting up your new balance must be strictly observed. If the balance is not used according to these Operating Instructions, protection of the balance may be impaired and METTLER TOLEDO assumes no liability. It is not permitted to use the balance in explosive atmosphere of gases, steam, fog, dust and flammable dust (hazardous environments).

4 Setting up the Balance The balance must be disconnected from the power supply when carrying out all setup and mounting work. 4.1 Unpacking and Delivery Inspection a) Open the packaging and carefully remove all components. b) Check the delivered items. The standard scope of delivery contains the following items: Components Balances with round weighing pan 0.
4.2 Installing the Components 5 4 3 2 1 Balances with readability of 0.1 mg, with draft shield (235 mm) Place the following components on the balance in the specified order: Note: Push the side glass door (1) back as far as will go.
Balances with readability of 1 mg, with flex draft shield (105 mm) 6 5 Place the following components on the balance in the specified order: 4 a) Place bottom plate (1) (push and turn) 3 b) Place pan support (2) with weighing pan (3). 2 c) Unfold the draft shield frame (4) and place it cor rectly. 1 d) Insert the glass panels (5) into the draft shield frame.
Balances with readability of 0.1 g with square weighing pan 2 1 Place the following components on the balance in the specified order: ● Pan support (1) ● Weighing pan (2) C 4.3 Selecting the Location and Leveling the Balance Your balance is a precision instrument and will thank you for an optimum location with high accuracy and dependability. 4.3.1 Selecting the Location Select a stable, vibration-free position that is as horizontal as possible.
Balances with 4 leveling feet a) First turn the two rear leveling feet all the way in. b) Adjust the two front leveling feet as previously described. c) Turn the rear leveling feet down onto the surface for extra stabiliz ing safety, so the balance cannot tilt over under eccentric loads. 4.4 Power Supply Allow your balance to warm up for 30 minutes (0.1 mg models 60 minutes) to enable it to adapt itself to the ambient conditions. 4.4.
battery fully 2/3 full When the balance is operating on its batteries, the battery symbol in the display lights up. The number of segments that are lit is an indica tor of battery condition (3 = fully charged, 0 = discharged). When the batteries are almost completely discharged, the battery symbol flashes. 1/3 full battery empty Inserting / Replacing Batteries The balance must be disconnected from the power supply when carrying out all setup and mounting work.
Transporting Over Short Distances For balances with a draft shield: Observe the following instructions to transport your bal ance over a short distance to a new location: Never lift the balance using the glass draft shield. The draft shield is not sufficiently fastened to the balance. Transporting Over Long Distances If you would like to transport or send your balance over long distances, use the complete original packaging. 4.
Requirement: To carry out this operation, in the menu topic "CAL" (Adjustment) of advanced menu "ADJ.INT" must be selected.

To avoid a division by zero, the fac tor division is not calculated at zero. d) Unload sample weight.
16 Application "Density" The "Density" application allows you to determine the density of solid bodies and liquids. Determination of the density uses Archimedes' principle according to which a body immersed in a fluid undergoes an apparent loss in weight which is equal to the weight of the fluid it displaces. To determine the density of solid bodies, we recommended you to work with the optional density kit which contains all the attachements and aids needed for convenient and precise density determination.
If you have selected water or ethanol as the auxiliary liquid: 20.0 21.8 a) Enter the current temperature of the auxiliary liquid (read off on thermometer). Change the value by scrolling up «+» or down «-». The temperature ranges from 10 °C to 30.9 °C. b) Press « » to confirm the value. Note: The densities of distilled water and ethanol in the range 10 °C to 30.9 °C are stored in the balance. If you have selected a freely definable auxiliary liquid: 01.

21 Error and Status Messages 21.1 Error Messages Error messages in the display draw your attention to incorrect operation or that the balance could not execute a procedure properly. Error Message Cause Rectification NO STABILITY No stability. WRONG ADJUSTMENT WEIGHT Wrong adjustment weight on pan or none at all. Reference for piece counting too small. EEPROM (memory) error. Ensure more stable ambient condi tions. If not possible, check settings for environment.
21.2 Status Messages Status messages are displayed by means of small icons. The status icons indicate the following: Status Icon Signification Service Reminder Your balance is due for servicing. Contact your dealer's customer service department as soon as possible to have a technician service your balance. (See menu topic "SRV.
22 Cleaning and Service Every now and then, clean the weighing pan, draft shield element, bottom plate, draft shield (depending on the model) and housing of your balance. Your balance is made from high-quality, durable materials and can therefore be cleaned using a damp cloth or with a standard, mild cleaning agent. Please observe the following notes: ● The balance must be disconnected from the power supply ● Ensure that no liquid comes into contact with the balance or the AC adapter.
23 Interface Specification 23.1 RS232C Interface Each balance is equipped with an RS232C Interface as standard for the attachment of a peripheral device (e.g. printer or computer). Schematic Item Specification Interface type Voltage interface according to EIA RS-232C/DIN66020 CCITT V24/V.
● The possible input for "text" is a sequence of characters of the 8-bit ASCII character set from 32 dec to 255 dec. ● Each command must be closed by CRLF (ASCII 13 dec., 10 dec.). The characters CRLF, which can be inputted using the Enter or Return key of most entry keypads, are not listed in this description, but it is essential they be included for communication with the balance. Example S – Send stable weight value Command S Get the current stable net weight value.
