The power supply to the switch, simply move it into the position corresponding to the required voltage.After that, with a voltmeter, make sure that it meets required.In unregulated unit-load output voltage may be somewhat overstated.The first time you load it the device which is not a pity to spoil (such as a light bulb, which consumes the same current), and after making sure that the voltage has dropped to a nominal, proceed to use the unit.
to the power supply with continuously variable output voltage with the handle outside, connect a voltmeter, if it is not a part of the unit.If you are around the handle has a graduated scale, set the voltage on it, but the accuracy of its installation will be small.Better check it on the voltmeter.
In some units there is n
ot one, and two handles.One of them allows you to set the voltage roughly other - exactly.Scale next to regulators such units do not usually have, but they are almost always equipped with a built-in voltmeter.
If the unit is equipped with a built-in voltmeter, before using the check the accuracy of exemplary, higher class.Further to carry out such inspections at least once a year.
very convenient power supplies Decades.In such a device set the voltage values bit by bit by rearranging the individual decades.Remember that when rotating in the opposite direction of the figure 0 is replaced by the figure 9, which could lead to a sharp increase in the output voltage and load of the system.
existing power supply and microprocessor controlled.They input voltage is performed using a keyboard or the encoder.In addition, some of these units have a menu that allows you to change the values of some auxiliary parameters.When working with such units be careful not to accidentally enter the keyboard high voltage value by typing, for example, this or that figure doubled.
number of power units equipped with not only a voltmeter and an ammeter.Use them to monitor the current consumed by the load, check its accuracy exemplary ammeter higher class.If the current consumption of the load, it is necessary to restrict use in some existing blocks automatic switching from the voltage stabilization in constant current mode.Switches will be carried out at the moment when the value of current through the set.The corresponding adjustment can be carried out also handles Decades or through the menu.When using decade switches to set the value of current and protection operation can be blind without the ammeter.
Tip 2: How to set the timings for the memory
In that situation, when you want to increase the performance of your computer without having to install new equipment, it is recommended to change the settings of CPU and RAM memory .Typically, these devices are set up in the menu BIOS.
1 Turn on the computer and wait for the operating system.Test the status of operational memory .To do this, open the "Start" menu and go to the control panel.Now, go to "System and Security" and select "Administrative Tools."
Run "Checking memory Windows».Confirm the restart your computer and wait for the completion of the test parameters of the RAM.Now again, restart your computer and hold down the Del.After logging in, open the BIOS menu item that allows you to change the settings of CPU and RAM memory .
first increase the voltage applied to the strips of RAM.This will prevent the emergency shutdown of the computer.Now find four indicators memory timings .Select the fourth paragraph and reduce its value to 0.5.Now apply the new settings of the RAM by choosing Save & amp;Exit.
After starting the operating system, repeat the procedure check the status of RAM memory .If the test did not reveal any errors, repeat the process of entering the BIOS menu.Reduce the value of the index of the third paragraph by one.Repeat algorithm to reduce timings and check the status of RAM as long as the testing program does not detect errors.
periodically raise the voltage supplied to the board RAM memory .If you require even greater performance RAM, then configure the frequency of the bus.Typically, the figure is over timings.Increase the frequency of the bus of 20-30 Hz.If the test program will not give the status of RAM errors, continue to improve the rate of frequency.
In no case do not reduce performance drastically delays.This may cause not only a malfunction of the computer, but also to the deterioration of memory cards .
