Safety precautions

This product complies with the requirements of the following directives of the European Union for CE conformity: 2014/30/EU (electromagnetic compatibility), 2014/35/EU (low voltage), 2011/65/EU (RoHS).
To ensure the safe operation of the equipment and eliminate the danger of serious injury due to short circuits (arcing), the following safety precautions must be observed.
Damages resulting from failure to observe these safety precautions are exempt from any legal claims

• Prior to the connection of the equipment to the mains outlet, check that the available mains voltage corresponds to the voltage setting of the equipment.
• Connect the mains plug of the equipment only to a mains outlet with an earth connection.
• Do not practice the device unattended.
• The instrument must be set up so that the power plug can be removed from the socket easily.
• Do not place the equipment on damp or wet surfaces.
• Do not subject the equipment to direct sunlight or extreme temperatures, extreme humidity, or dampness.
• Replace a defective fuse only with a fuse of the original rating. Never short circuit fuse or fuse housing
• Conduct measuring works only in dry clothing and in rubber shoes, i. e. on isolating mats.
• Comply with the warning labels and other info on the equipment
• Do not cover the ventilation slots of the cabinet to ensure that air is able to circulate freely inside.
• Do not insert metal objects into the equipment by way of the ventilation slots
• Do not place water-filled containers on the equipment (danger of short-circuit in case of knock over of the container)
• Do not operate the equipment near strong magnetic fields (motors, transformer etc.)
• Do not subject the equipment to shocks or strong vibrations
• Allow the equipment to stabilize at room temperature before taking up measurements (important for exact measurements)
• The meter is suitable for indoor use only.
• Do not operate the meter before the cabinet has been closed and screwed safely as the terminal can carry voltage.
• Periodically wipe the cabinet with a damp cloth and mid-detergent. Do not use abrasives or solvents.
• Do not store the meter in a place of explosive, inflammable substances.
• Do not modify the equipment in any way
• Do not place the equipment face-down on any table or workbench to prevent damaging the controls at the front.
• Opening the equipment and any service- and repair work must be performed by qualified service personnel. Repair work should be performed in the presence of a second person trained to administer first aid if needed.
• – Measuring instruments do not belong to children’s hands-

Cleaning the cabinet
Prior to cleaning the cabinet, withdraw the mains plug from the power outlet. Clean only with a damp, soft cloth and a commercially available mild household cleanser. Ensure that no water gets inside the equipment to prevent possible shorts and damage to the equipment.

Introduction

Digitally controlled, high-precision DC power supply with variable voltage and current setting. An advanced microprocessor controls the generation, display, control, and protection of output voltage and current. This technology improves the accuracy of the generation and control of the output voltage and current and it also facilitates the operation and the reading of the values.
Henceforth should be emphasized that the voltage can be fixed over the whole range, making the convenience is increasing and unnecessary, inaccurate, steps can be prevented.

Caution!
The PeakTech 6075 provides a keylock function. Please read chapter 5.5 on page 25 for more detailed information.
Caution!
Laboratory Power Supplies are not designed for charging batteries. Any use of this type can cause serious damage to the device, which are exempt from any legal claims whatever.
