Whtechnology equipment and domestic appliances you will be looking for efficiency, accuracy and reliability in your electronic test gear.
As a result of changing marketing condition the Seaward Company has designed and manufactured the professional pat testing kit, the Seaward Primetest 350 Portable Appliance Tester. This measurement instrument is five products in one - pat tester, Bluetooth scanner, printer, checkbox and record keeping software. This instrument performs all the pat tests recommended by the IEE (Institution of Engineering and Technology; basically, the IEE is a code of practice for the in-service inspection and testing of electrical equipment) including substitute leakage, and ELCB (earth leakage circuit breakers or safety switches; ELCBs are often known by other names, e.g. RCD ) trip time.
To begin testing, the domestic appliance (such as the kitchen blender) is connected to the Seaward Pat Tester 350. The asset ID is entered either by scanning the bar code on the kitchen blender, in this case, (or any other appliance) or manual entry using the instrument's keypad. Than simply choose the test sequence and enter the site, location, and test period in the appropriate boxes. After this the tests should execute. When the first test is done using the "User Comments" like the description of the appliance tested (in this case, the kitchen blender) can be entered before saving the test data in the instrument's memory. Than a "Pass/Failed" bar code label is produced via the Seaward Test n Tag Elite Printer. You should tape the label onto the blender.
The layout of the label can be simply personalized by the user to place the company logo and other important information such as telephone number. Every label must show the date of the test, retest date, the name of the person performing the test, and the test status. Once testing is completed the Seaward Pat Tester can download the test results and data via Bluetooth or USB to a personal computer's memory. Seaward's PATGuard Software is perfect for logging test results for auditing as well as producing reports for clients. This Seaward Pat Tester is definitely a great and time saving instrument.
The Primetest 100 is a Seaward Pat Tester which is extremely user-friendly backed up with an easy-to-use manual. The instrument has a three button operation with dial diagrams to ensure you are using the correct test for an appliance (e.g. kitchen blender) or a test lead. To use this pat tester just connect the plug of any kitchen appliance into the instrument's socket on the front of the pat tester. Than simply connect the lead to the exposed metal part of the appliance and press the appropriate "Class" button. The instrument will detect if the wrong "Class" button has been pressed and indicate which button should be used. During the measurement sequence the Seaward Pat Tester will test earth continuity, insulation resistance, and leakage current. The kitchen blender must be switched on to test insulation resistance and leakage current. If all three values are within acceptable limits the LCD display will indicate, "PASS."
To test an IEC (International Electrotechnical Commission) mains lead you can use the Seaward Primetest 100 PAT Tester. When testing an IEC mains lead it should be connected between the socket on the front of the pat tester and the IEC socket on top of the instrument and the "Cord" button depressed. The pat tester runs through the inspection to check the earth continuity, insulation resistance, and wiring polarity and displays the test data.
The Seaward PAT Checkbox is another useful instrument. It is used to verify that the Seaward PAT tester you are using is within its calibration limits. To do this first you must connect the Pat Checkbox to the Pat Tester (for an example the Seaward Pat Tester 100) socket (basically, it is compatible with any pat tester fitted with the UK made in socket). Earth continuity can also be checked by connecting the lead to the test point, "TP1" on the front panel of the instrument. The "Class 1" button is pressed on the pat tester to start the measurement sequence. Than the pat tester will test the reference earth resistance value in the pat check box and display this reading along with the tick enunciator. Than the instrument LCD display will show "Lo/ Lord." The "Class 1" button is pressed again to proceed with insulation resistance measurement sequence. And the Seaward Pat Tester will now test the reference insulation resistance value in the pat check box and show this reading on a display with the tick enunciator. Instrument will than measure the leakage. To confirm "Class 2" values you need to hold the mains lead on the test point and than simply press "Class 2" key.
To test an ELCB you can use the Seaward Primetest 220 PAT Tester. The ELCB is plugged into an outlet and reset. Than the instrument is connected to the multiway adapter by plugging its cord into the outlet. Than you need to select ELCB on the Seaward Pat Tester rotary switch. The tester will than measure the incoming main supply for correct live neutral polarity and the valid earth connection. If the main supply is correct both the "PE" and "PN" enunciators on the instrument will flash green on the instruments LCD display. Finally, the "Test" button is pressed to begin the measurement sequence. The pat tester will trip the ELCB and display the time needed for the instrument to finish testing.
The Seaward 1557 17th Edition Multifunction Tester is the first calibration verification instrument for pat and installation testers. This instrument can be used to verify the accurate operation of all tests commonly found on the 17th edition installation instruments or pat tester equipment. This multipurpose instrument can also be used on ELCB protective circuits and to check the operation of ELCB and pat testers without tripping the ELCB.
If you want to test the 17th edition test instruments simply plug it into a mains supply. The LED lights on the Powerchecker 1557 will illuminate to show it is turned on. To perform continuity check, you need to turn the dial to RPE and connect the tester to common terminal and "0.5 ohm" terminal. Than you simply hit the "Test" key. After this is completed, make sure you confirm that the reading is within the specified range. Than simply change the resistance to 2 ohms and hit the "Test" button again. Again, you must check that the displayed data is within a specified range. The "In" indicator will flash to show that the test current is correct.
To check the open circuit test voltage you must move the red lead into the "O/C" socket and hit the "Test" button. The "Un" indicator will flash if the open circuit test voltage is accurate. To check the operation of an ELCB tester plug the Seaward Pat Tester into the Powercheck 1557 and than turn the test current to match the test current on the tester.
The Seaward Powercheck 1557 can also be used on ELCB protected circuits without tripping the supply ELCB. Also, it can be used to test the insulation. For pat tester verification, simply plug the power check into the pat tester. After this, just select the "Pat" feature on the Powercheck 1557. This multifunction instrument is also capable of testing insulation, flash, sub leakage, leakage, and touch leakage. Overall, the Powercheck 1557 does not trip an ELCB protective circuit, verifies that your PAT and installation instruments are operating within specified range. The 1557 is compatible with all pat testers. This is a rugged and robust instrument.
And to complete the electrical measurement kit, get the Powerplus 1557 Installation Tester with built in 17th Edition Certificates. This is an installation tester capable of transferring test and inspection certificates between a personal computer and test instrument, removing the need for user to take a paper certificates or a PDA on site.
Using onboard certificates test and inspection information is saved right on the instrument saving time, reducing the opportunity for error and extremely reducing test and inspection times. Blank certificates are available on both the personal computer and the instrument itself; if needed the certificate can be partly filled out before it is transfered to the installation tester. When a tested value is required the Seaward Powerplus 1557 will automatically enable the right testing sequence and the "Test" button will illuminate. After the testing has been done the instrument automatically places it in the correct certificate box.
You can simply navigate around the onboard certificate by using the arrow keys to go to the needed section. Progress can be saved at any point that you make sure that the measurement data is kept. This certificate assistance can be used to scan the certificate and highlight any blank fields. These certificates can be transferred and saved to a personal computer for later reviewing.
Certificated can be over printed on to ECA (Electrical Contractors' Association), NAPIT (National Association of Professional Inspectors and Testers) or NICEIC (electrical contracting industry's independent voluntary body for electrical installation matters throughout the UK) preprinted stationary. Overall, the Seaward Powerplus 1557 Installation Tester is a high performance multi-function instrument. It can transfer test and inspection certificates between personal computer and tester. Also, it is capable of recording test and inspection information directly to certificate. It features a built-in certificate validation. This is a fast and efficient instrument that can save time and reduce paperwork.
