POWERING DOWN THE TESTER

9.0 POWERING DOWN THE TESTER

Note: The test system must always be shut down in a controlled

manner or data may be lost.

9.1 In order to properly power down the tester first all running processes must be halted and the disk drives must be unmounted. This process requires system root user privilege and must be performed by the test engineering department or its authorized representative.

9.2 Exit from all running BT-BASIC windows. At the HP VUE graphical interface, click the mouse on the terminal icon on the Workspace Manager bar displayed at the bottom of the screen.

9.3 This will open an hpterm window on the screen. If not currently logged into the system

as user root, type the following at the command line $ prompt: $ SU -root and press

the “ENTER” key on the keyboard.

9.4 Enter the correct password when queried by the system.

9.5 Type shutdown –h 1 at the command line # prompt and press the “ENTER” key on

the keyboard. The system will broadcast a message to all logged in users informing them that the system will be shut down in 1 minute.

9.6 When the shutdown procedure has completed the following message will appear on the

tester display:

System has halted

OK to turn off power or reset system

9.7 It is now okay to power off the tester. Caution must be exercised if the tester hardware

configuration consists of separate hard disk units and signal processor unit. In this case power off the Signal Processing Unit (SPU) first. Then power down the disk drives and other peripheral devices afterwards.

BT-BASIC commands used

8.10 Some of the most frequently used BT-BASIC commands used are: msi Changes default working directory. Mass storage is Same as “msi” cat Catalogs (list)the node names in the specified directory. get Brings the contents of a file into the system workspace. load Same as “get”. msi$ Returns the directory pathname of the current working directory. msi “..” Backs up one directory level. findn Locates the next occurrence of the a given sting in the workspace. 8.11 If you wish to invoke the HP Board Graphics Viewer, type board graphics at the BT-BASIC command line and press the “ENTER” key on the keyboard. 8.12 A HP Board Graphics Viewer window should now appear

Perhitungan & Cara Merubah Kumparan Blender Dari 220 V Menjadi 12 V

Seperti yang telah dijelaskan pada buku “menggulung motor listrik arus bolak-balik, servis peralatan listrik rumah tangga kelompok penggerak dan perbaikan peralatan listrik pertukangan”, bahwa motor penggerak yang digunakan pada perlatan listrik rumah tangga dan pertukangan seperti blender, mixer, bor tembak, gerinda dsb menggunakan jenis motor universal. Motor universal adalah jenis motor listrik yang dapat disuplai dengan sumber listrik arus bolak-balik (AC) dan arus searah (DC). Jadi peralatan-peralatan listrik rumah tangga dan pertukangan tersebut yang biasanya kita suplai dengan sumber listrik AC dari PLN atau Genset sebesar 220 V sebenarnya dapat juga kita suplai dengan sumber listrik DC yang tentunya tegangan juga harus sama yakni 220 V. Yang menjadi permasalahan bagaimana kalau peralatan listrik rumah tangga atau pertukangan tersebut, sebagai contoh misalkan blender yang ingin digunakan atau dioperasikan pada tempat yang tidak terdapat sumber listrik PLN ata

BT-BASIC command line

8.8 At the BT-BASIC command line type the command msi and the directory path, then press the “ENTER” key on the keyboard. Example: msi ‘/hp3070/boards/aspect/main’ 8.9 At the BT-BASIC command line type the command get ‘testplan’ and press the ENTER” key on the keyboard. You should now see the body of the testplan file displayed in the work space of the BT-BASIC window. 8.10 Some of the most frequently used BT-BASIC commands used are:

Testhead

4.3 Testhead The testhead is that portion of the tester that supports the PIN, ASRU and Controller cards. The testhead is divided into two BANKS and each BANK is divided into two MODULES, see figure 2 below. Bank 1 contains modules 0 and 1, bank 2 contains modules 2 and 3. The test fixtures are placed on the banks of the tester and locked down for board testing. The testhead cards interface to the test fixture through the spring loaded pogo pin “nails” at the top edge on each of these card types. 4.4 Support Bay The support bay is a stand-alone cabinet that houses the power supplies for the Unit Under Test. This bay also houses the test station power distribution unit and test station controller on earlier models. 4.5 Emergency Shutdown Switch The emergency shutdown switch is the large red button located at the lower left corner on the front of the testhead. It turns off all AC power to the testhead, and is equivalent to turning off the m

Kelebihan dan Kekurangan Saluran Listrik Jenis Saluran Udara dan Saluran Bawah Tanah

Berdasarkan pemasangannya, saluran distribusi dibagi menjadi dua kategori, yaitu : saluran udara (overhead line) merupakan sistem penyaluran tenaga listrik melalui kawat penghantar yang ditompang pada tiang listrik. Sedangkan saluran bawah tanah (underground cable) merupakan sistem penyaluran tenaga listrik melalui kabel-kabel yang ditanamkan di dalam tanah. 1. Saluran Bawah Tanah (Underground Lines) Saluran distribusi yang menyalurkan energi listrik melalui kabel yang ditanam didalam tanah. Kategori saluran distribusi seperti ini adalah yang favorite untuk pemasangan di dalam kota, karena berada didalam tanah, maka tidak mengganggu keindahan kota dan juga tidak mudah terjadi gangguan akibat kondisi cuaca atau kondisi alam. Namun juga memilik kekurangan, yaitu mahalnya biaya investasi dan sulitnya menentukan titik gangguan dan perbaikannya. Kedua cara penyaluran memiliki keuntungan dan kerugian masing-masing. Keuntungan yang dapat diperoleh dari suatu jaringan bawah tanah adalah
