6、 a wide viewing angle type of display with high intensity, and clearly indicates information in clearly readable large letters and in color annunciators. The indicated information includes test conditions, instrument status, readback current, result of pass/fail judgement, etc., assisting you to con

7、duct your tests accurately and efficiently. 8. Analog/digital voltmeters The TOS5052 is furnished with an analog voltmeter (5% full-scale) and a digital voltmeter (1.5% full-scale). The analog voltmeter serves as an output indicator and the digital voltmeter as a high-precision output voltmeter for

8、accurate and prompt testing. (Neither analog nor digital voltmeters can be used to measure any external voltages that are present outside the TOS5052. An attempt to apply an external voltage to their output terminal would cause fatal damage to the TOS5052.) 9. A digital ammeter The TOS5052 has a dig

9、ital ammeter to measure the current that flows through the DUT (device under test). 10. A window comparator for pass/fail judgement The TOS5052 has a window comparator for pass/fail judgment with reference to both upper (U) and lower (L) criteria (cutoff current). The comparator generates a FAIL sig

10、nal when the measured current that flows through the DUT is greater than the preset upper limit criterion or even when it is less than the preset lower limit criterion. The L FAIL detection function contributes to improve the test reliability by detecting open-circuiting or imperfect contacting of t

11、he test leadwires. Separately for each of U type and L type of fail, the TOS5052 indicates a fail annunciator message on its display and delivers a fail event signal, allowing you to immediately find out the type of the fail. You can preset the upper limit and lower limit currents (cutoff currents)

12、mutually independently of each other (0.1mA to 110mA, AC). 11. A digital timer The timer allows you to preset the period during which the test voltage is to be applied to the DUT. The preset range is 0.3 to 999 seconds. When the timer function is ON, the preset period is decremented and the timer in

13、dicates the remaining period; when it is OFF, time is incremented and the timer indicates the elapsed period. 12. Remote control provision The tester has provisions for remote start/stop control operation. That is, it has a 5-pin DIN connector (for the optional Remote Control Box or High Voltage Tes

14、t Probe) on its front panel and a 14-pin Amphenol connector on its rear panel. The remote control function, together with the status signal function, will help you conduct efficient automatic labor-saving tests. TOS5052SETUP1-5 Secure adequate space around the power plug. Do not insert the power plu

15、g to an outlet where accessibility to the plug is poor. And, do not place objects near the outlet that would result in poor accessibility to the plug. 1.3 Checking AC Line Voltage The AC line requirements of the TOS5052 are as follows. Voltage tolerance range : 90 V to 110 VAC Allowable frequency ra

16、nge : 45 Hz to 65 Hz The TOS5052 might not only malfunction but also develop a mechanical breakdown at AC line voltage outside the above range. Make sure that the TOS5052 is run within the specified AC line voltage range. Do not use the AC power cable that comes with the product as a AC power cable

17、for other equipment. The TOS5052 is available in three models with different AC line requirements. Contact your Kikusui agent. 1. 104 to 125 VAC (110/120VAC model) 2. 194 to 236 VAC (220VAC model) 3. 207 to 250 VAC (230/240VAC model) WARNING The AC line voltage must be adjusted only by the Kikusui-

18、qualified service engineer. Before turning on the TOS5052, make sure that the AC line voltage is set up correctly. The AC line voltage setting (labeled SETTING SUPPLY) is indicated on the rear panel. No mark indicates the default 90/110 VAC setting. The AC line voltage of the TOS5052 is set at the f

19、actory or by a qualified service engineer. If the AC line voltage range is altered, a mark is placed on the left of the voltage label.

20、S5052 2) Initial Setup Procedure 1.-Make sure that the POWER switch is in the OFF position. 2.-Connect the AC input power cable (supplied as an accessory) to the AC LINE connector on the rear panel. 3.-Connect other end of the AC input power cable to an AC line outlet of the correct voltage. 4.-Keep

21、ing the SHIFT key pressed, press the POWER switch. The Vacuum Fluorescent Display will start illuminating, indicating that power has been turned ON. (The DC illuminator turns on but it has nothing to do with the operation of the TOS5052.) 5.-Release both SHIFT key and POWER switch. 6.-Within several

22、 tens seconds from the above, the Version Number and Model Number of the TOS5052 will appear on the display screen. The three digits on the left hand side indicate the version number; those on the light hand side are of the three least-significant digits of the model number. 7.-The initial test setu

23、p data will appear on the screen. If no messages at all appear on the screen when more than 60 seconds has elapsed from the above, repeat the procedure all over again from its beginning. 3.3 Checking the Tester Operation The TOS5052 will generate no output unless you reset protection using the inter

24、lock function for the SIGNAL I/O connector on the rear panel. Run your TOS5052 tentatively using the attached 14-pin Amphenol plug. WARNING Pins 9 and 14 of the 14-pin Amphenol plug are short-circuited to reset protection. Before making a practical withstanding voltage test, reset the interlock func

25、tion. For details, see the section entitled Interlock Function. CAUTION This operation check initializes the setup data. Any existing setup values are lost. TOS5052OPERATING PRINCIPLE5-3 Voltmeters The TOS5052 is furnished with a digital voltmeter (1.5% full-scale) and an analog voltmeter (5% full-s

26、cale). （a）Digital voltmeter This digital voltmeter divides the output voltage with high-precision high- voltage resistors and supplies the output to the AC/DC converter circuit where DC voltage is generated. This DC voltage is sent to the A/D converter and indicate the display during the test. （b）An

27、alog voltmeter The analog voltmeter rectifies the current that flows through the divider resistors to drive the DC ammeter. Current detector circuit The current detector circuit converts the current flowing over the output terminal to develop a voltage across the reference resistor. This voltage is

28、converted in the AC/ DC converter circuit to a DC voltage. The digital ammeter takes in this voltage using its A/D converter and indicate it on the display. The ammeter range and resolution are determined by the UPPER value. Upper cutoff current0.1-7.5mA7.6-30mA31-110mA Resolution4A16A64A i10mA.mA.m

30、efined upper or lower cutoff current. When the current proves to be greater than the upper cutoff current, the judgment circuit flags a withstanding voltage error and shuts off the test voltage. It also signals a broken high-voltage test leadwire or poor connection condition and shuts off the test v

31、oltage when the current proves to be smaller than the lower cutoff current. Control circuit The control circuit contains a 8-bit single-chip CPU that provides voltage and current measurement control, pass/fail judgment, test time and test voltage rise time management, and sequence control. It saves

32、the test voltage, cutoff current values, and test time in EEPROM before the CPU is reset following the detection of the POWER switch off condition. 7-2SPECIFICATIONSTOS5052 7.1 Specifications Item Output block Output voltage range0.50 kV to 5.00 kVAC (100 mA output possible range) Voltage setting ra
