INTRODUCTION 4 General Description The S1-1052 is a microprocessor controlled 10 kV insulation tester offering measurement capability of up to 35 T. The instrument performs automatic tests and has data storage and data retrieval facilities. Polarizati
17、on index and dielectric discharge tests are performed automatically, and test duration and voltages can be adjusted according to user preference for these tests. A step voltage test can be performed automatically, with a default voltage of 1 kV , and test duration of 5 minutes. It is possible for th
18、e user to set different voltages and test durations for the step voltage test. The S1-1052 can be powered from the mains supply or by its own internal rechargeable battery, which provides for at least 4 hours of continuous testing. A battery level indicator on the LCD display indicates battery capac
19、ity. Connecting power to the mains supply connector will automatically charge the battery whether the instrument is switched on or off, except during testing. A high level of internal isolation allows the instrument to be used while the unit is supplied from the mains. An internal battery management
20、 system switches the instrument off after ten minutes of inactivity. If the battery approaches a very low state of charge the instrument turns itself off, and mains power must be applied before the instrument can be used again. Recorded test results and settings will not be lost when the instrument
21、is switched off. A comprehensive LCD display shows resistance, current, capacitance, time constant, voltage, timer measurements, and figure of merit measurements such as polarisation index. POWER LEAD AND BATTERY CHARGING 5 If the power lead supplied is not suitable for your mains connection, do not
22、 use an adaptor. Always use a power lead fitted with the correct plug. The instrument is fitted with a two-pin IEC60320 power inlet. Most power leads are made with three-core cable, so the ground connection will not be used. Power lead connection table ConnectionUK/InternationalUSA Earth/Ground Yell
23、ow/Green Green Neutral Blue White Live (Line) Brown Black If using a fused plug, ensure that it is fitted with a 3 Amp fuse. The instrument can be powered from 85 - 265 Vrms a.c. at 50/60 Hz. The battery will charge as long as the mains supply is connected, except when a test is in progress. The pow
24、er On/Off button has a green LED, which illuminates when mains power is present. For optimum battery life, charge the battery after each use. A completely exhausted battery will take 14 hours to recharge. INSTRUMENT CONTROLS AND INDICATORS 6 Measurement terminals -veguard+ve RS232USBLine input Time

Pressin
27、g either test voltage L or M button will then display the test voltage immediately before the end of the test. Test start / stop button A test will only start if this button is pressed, held and then released as soon as the red high voltage warning indicator LED lights. The LCD and red LED high volt
28、age warning indicators flash when the test starts. A test will not start if the button is released before the red LED shows, or pressed continuously for longer than 5 seconds. This is a safety feature to prevent a test being started inadvertently. The presence of a voltage greater than 50 V on the t
29、est leads is indicated with flashing high voltage warning indicators. Testing is disabled if the external voltage exceeds 80 V . Testing will stop if the test start / stop button is pressed again, the preset test time is reached, or, if the unit is not in burn mode, insulation breakdown is detected.
30、 When a test has finished, the instrument will discharge the load, which may take some time. The operator must always check the load has been discharged before touching the test leads. /I button Pressing this button toggles the digital and secondary displays. The details available when scrolling the
31、 secondary display will depend upon the test mode selected, whether timers T1 and T2 have been set, and the duration of the test. The digital display toggles between insulation resistance and current. Power On/Off button The instrument will only turn on if this button is pressed, held and then relea
32、sed when the display responds. The instrument will not turn on if the button is released before the display responds, or if the button is held down for too long. This is a safety feature to prevent the instrument being inadvertently turned on. The instrument is turned off either by pressing the butt
33、on again, or if the instrument is running on the battery, by timing out after 10 minutes of inactivity. Upon switching the instrument on the display will first show Ini while it undergoes a self-checking routine. When Ini disappears, the instrument is ready for use. Test voltage L and M buttons Usin
34、g these buttons one of six test voltages can be selected: 250 V , 500 V , 1 kV , 2.5 kV , 5 kV , and 10 kV . The selected voltage is shown on the display. A non standard voltage between 50 V and 10 kV can be selected by holding down the Fn function button whilst operating the buttons. The selectable
35、 voltage is adjustable in 10 V steps between 50 V and 1 kV , and adjustable in 25 V steps between 1 kV and 10 kV . An auto repeat facility is enabled when the button is held down, allowing faster travel through the range. If there is an external voltage greater than 50 V on the test leads, the high
36、voltage warning indicators are flashed, and the display shows this voltage instead. The instrument will not perform a test if this voltage is greater than 80 V . During a test the display shows the actual voltage on the test leads. If the test voltage is changed during a test, the new test voltage w
