Page 4: General Information
GENERAL INFORMATION Introduction This section contains a general description of your power supply as well as its performance specifications. Information about options and accessories are also provided. The TPS-3025 series has been designed and tested according to EN-61010-1, Safety requirement for Electronic Measuring Apparatus. - Page 5 Under certain conditions, dangerous voltages may exist even with power cable removed. To avoid injuries, always disconnect power, discharge circuits and remove external voltage sources before touching components. DO NOT SERVICE OR ADJUST ALONE Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present.

Page 8: Installation
INSTALLATION Introduction This section contains instructions for checking and mounting your power supply and connection your power supply to AC power. The power supply generates operating magnetic which may affect the operation other instruments. If your instrument is susceptible to operating magnetic fields, position it more than three inches from the power supply. -
Page 9: Getting Started
GETTING STARTED Front panel controls and output terminals Note ： most soft keys have two functions. The first function of the key is function entry (i.e. + Vset, -Iset, Tracking etc.)The second function for the soft keys is data entry (ji. E. 0~9). REFER TO THE FIGURE A. - Page 10 point key. (15) Beep (3) : Beeper control key which toggle the beeper on or off. Numeric entry key for number three. (16) Enter : Enter the values on the display for the specified function and return the display to output-off mode or metering mode. (17) Clear : Used in conjunction with the numeric entry keys to clear partially set commands.
