1 Safety 1.1 Representations and symbols Important instructions, which involve safety, are highlighted with the appropriate mark: 1.2 Safety recommendations When using the weighing equipment in surroundings with increased safety requirements, the corresponding regulations must be observed. The weighing machine may only be used with the power adapter supplied exclusively for use with the weighing machine.
1.3 IP65 protection Your MRW weighing machine is rated to IP65. The IP rating system IP stands for Ingress Protection The rating’s first digit e.g. IP65 relates to the ingress protection against dust (6 means dust tight, see the table below) The second digit e.g.

2.2 Application, conformity 2.2.1 Correct use of the weighing machine The weighing machine may only be used for the weighing of solid-materials and of liquids filled into secure containers. The maximum allowable load of the weighing machine must never be exceeded, otherwise the weighing machine may be damaged.
3 Getting started with your weighing machine 3.1 Unpacking the equipment The machine is delivered in an environmentally-friendly carton, specifically developed for this precision instrument, which provides optimum protection for the balance during transportation. We suggest that you retain the original packaging in order to avoid transportation damage if re-shipping or transporting the balance and to allow the unit to be stored in the best conditions if it is out of operation for an extended period.
3.3 Assembling your weighing machine The weighing machine is delivered in partly dismantled condition. Assemble the individual components in the following sequence: Place the unit holder in position and add the weighing pan Insert the power adapter cable plug into the socket at the rear of the balance. 3.4 Choice of a suitable location The environment in which your weighing machine is used is very important. Air movement, temperature changes, vibrations, direct sunlight, etc.
4 Working with the application menu using the Intelligent Key-Pad 4.1 Display messages and key functions 4.1.1 Display messages 1. The STABLE icon indicates when the readings stabled. 2. The ZERO icon indicates when the weights tared to zero. 3. The LO-BAT icon indicates when running out of battery. 4.1.2 key functions 1. ON/OFF key turns the weighing machine on or off 2. UNIT key changes the weight units, kg, g, lb, oz, lb:oz 3. ZERO key sets display to zero or subtract the container weight 4.
4.2 Program options Besides performing accurate simple weighing, your versatile weighing machine can also perform pieces counting. 4.2.1 Pieces counting - Press ON/OFF key to turn on the scale - Wait for "0" to appear on the display.
5 Calibration - Using an External Calibration Weight: Calibration is required when the weighing machine is initially installed or if the scale is moved to a substantial distance from the original location. 10 minutes warm up of scale is always needed before calibration. Turn the scale on and then turn it off Press and hold ZERO key, and then press ON/OFF key to turn on the scale, the display will show CAPu= Press PCS key, display will show CAP.
6 Maintenance and service The weighing machine must be treated carefully and cleaned regularly. It is a precision instrument. For maintenance-work, the balance must be separated from the power supply (remove power adapter plug from socket). Also ensure that the balance cannot be reconnected to the power supply during the work by a third party. See Section 1.3 above regarding IP65. The scale may be washed down.
7 Transport, storage 7.1 Transportation and shipping of the weighing machine Your weighing machine is a precision instrument. Treat it carefully. Avoid shaking, severe impacts and vibration during the transportation. Take care that there are no marked temperature fluctuations during the transportation and that the weighing machine does not become damp (condensation). 7.
