[17] IMPORTANT: Before usage of product read with care and follow instructions. Store for later look-up. 1. Introduction a) Information for handling of instructions This instruction manual is part of the product “cmt Mini-Decade R1-3000” (hereafter “decade”) and gives you important notice and instructions for the intended use, safety and appliance of your new resistor decade. This instruction manual shall be kept in proximity of the decade.
[18] c) Limited Liability Every given information, data and notice refer to the latest state at date of print and refer to our best knowledge, expertise and experience. No right for claims can be derived from the given data, figures or descriptions. The manufacturer assumes no liability for damages due to inobservance of the given warnings and notices, misuse, inappropriate repair, unauthorised changes or use of nonapproved spare parts.
[19] 2. Safety a) Basic Safety Instructions For safe use of your decade consider the following basic safety instructions: Before every use check your decade for visible outer damage. Never use a damaged decade – there is a electric shock hazard, if you connect your damaged decade to voltages higher than 50 V AC rms or 120 V DC ! Repairing of your decade shall only be undertaken by authorised enterprise or the manufacturer. Non-appropriate repair may result in severe dangers for the users.
[20] A warning of this risk level indicates a possible damage of your decade and / or your equipment and points to a particularly noticeable fact. Follow the instructions to avoid damage of your equipment. A warning of this risk level indicates a possible damage of your decade and / or your equipment. Follow the instruction to avoid damage of your equipment. A notice gives additional information, which assists you in proper using your decade.
[21] 3. First Use a) Scope of Delivery • 1 Mini-Decade R1-3000 • 2 spare fuses • 1 instruction manual Check for the scope of delivery and possible visible damage. If you detect missing parts or damage due to transportation please contact the manufacturer. a) Packaging Packaging protects the decade from transportation damage. The packaging materials are selected from the point of view of their environmental friendliness and disposal technology and are therefore recyclable.
[22] is in the upper “1” position and “off”, if the corresponding slide switch is in the lower “0” position. The resulting total resistor value is calculated by the sum of all single activated resistors. refer to the example at the back side of the decade: Part from figure on the back side of the decade: It displays the connections of the decade. Right in black is the common connection. If you additionally use the middle (red) connection only the totally activated resistor value R is applied.

[24] c) Maximum Power Rating The decade has a total maximum power rating of 3 Watt. The maximum power rating shall not be exceeded, as damage or even destruction of the decade may occur. Limit applied voltage in relation to maximum activated resistor according to table 1.

[26] In relation to the activated resistor value the maximum allowed operational voltage Vmax may possibly be significantly lower than the maximum voltage of 250 VAC rms / DC due to the maximum power rating of 3 W ! Up to a maximum activated resistor value of 20kΩ the applied voltage must be lower than the maximum voltage of 250 V to avoid overloading of the resistors. Limit voltage to be applied according values given in table 1.
[27] If you have any further technical questions, please directly contact the manufacturer under: www.cosinus.de office@cosinus.de 5. Maintenance a) Change of Fuse The decade’s fuse may only be changed by a person belonging to the target group (cf. chapter 1 “Target group”).
[28] b) Fault Diagnostics If any disturbance occurs, first check the fuse for its function. In case of a triggered fuse, change it according to the previous chaper “change of fuse”. If the problem persists or the cause does not refer to the fuse, stop using the decade und contact the manufacturer, e.g. under office@cosinus.de. c) Calibrating Factory-provided every decade has been calibrated to ensure accuracy according to “technical data” in the appendix.
[29] 7. Disposal Do not dispose of the decade into normal household waste. This product is subject to the provisions of the European Directive 2012/19/EU (Waste Electrical and Electronic Equipment). Dispose the decade through an approved disposal centre or at your community waste facility. Pay heed to the currently applicable regulations. In case of doubt, please contact your local waste disposal centre. 8. Appendix a) Technical Data Maximum voltage ........................ Maximum power rating ........
