36、features of the S1-5010 should be regarded as additional safety features and not a substitute for normal safe working practice. When carrying out prolonged unattended tests, care should be taken ensure that harm or damage cannot be caused. When using theBURN feature, care must be taken that no harm

37、or damage can be caused. The test terminal area and side recess panel recess must be kept in a dry, clean condition. If any part of the instrument is damaged, it should not be used, but returned to the manufacturer or an approved repair company. Fuse replacement must be of the correct type and ratin

38、g. See Specification. Should the plug on the power cord not be the type for your socket outlets (receptacles), do not use an adaptor. Use a suitable alternative power cord. Wires in power cords are coloured as follows: -U.K / InternationalU.S.A. Earth (GroundYellow/Green Green NeutralBlueWhite Phase

39、 (Line) Brown Black If using a fused plug, a 3 Amp fuse to BS1362 should be fitted. Operation 13 The circuit under test must be completely de-energized and isolated before test connections are made Working with Capacitive Loads Charged Circuit Discharge Capacitive circuits charged to several kV can

40、be lethal. Circuits must be discharged before handling and connecting the test leads, and similarly before disconnecting the test leads. At the end of a test, any external capacitance is discharged automatically and the warning devices will continue to indicate until the terminals are in a safe cond

41、ition. While the instrument design incorporates maximum safety, safe working practice should assume that the instrument discharge circuit and warning devices could fail, and a shorting link should be connected across capacitive loads before handling them *Automatic discharge must not be relied upon

42、as an alternative to normal safe working practice. *Care must be taken to prevent capacitive circuits becoming disconnected during a test, leaving the circuit in a charged state. Dielectric Absorption Some capacitive items exhibit an effect called Dielectric Absorption. The dielectric can absorb cha

43、rge during the test. After the item is discharged, the absorbed charge is released back onto the capacitive plates effectively raising the voltage of the item, possibly to dangerous levels. Safe working practice dictates that tested items should be firmly shorted out with a shorting link, after disc

44、harge, until required for use Performing Tests - General Ensure that all test leads are clean and in good condition, and firmly connect them to the instrument and to the isolated circuit under test. Switch the instrument On by pressing the yellow On / Off switch once. The calibration check runs to c

45、heck the operation of the measurement system and correct any small calibration errors which may occur during the life of the instrument. The Menu screen is displayed on completion of the calibration check. If necessary, adjust the contrast setting using the .key. The key allows the back light to be

46、switched On or Off. (Switching the back light off, will conserve battery power by 10%). Select the required Test mode using the left hand cursor keys. Test time shown in the bottom right hand corner of the display indicates maximum test duration before it is stopped automatically. (Maximum test dura

47、tion is 90 minutes). Accept the default test time or use the right hand cursor keys to select and highlight the time indicator. Press the CHANGE key, followed by the + / -keys to set the required time. The required Test Voltage is selected with the right hand cursor keys. For specific types of test,

48、 pre-determined default voltages are set. For instance, the Step Voltage test only offers test voltage options of 2500 or 5000 volts. The VARI position gives the option to select a non- standard voltage between 25 and 5000 V d.c., or to continuously vary the voltage in 25 V steps during a test by us

If the battery becomes completely exhausted the instrument will refuse to operate. Recharge the battery as soon as possible. If the battery is not recharged it could degrade to a state where it will not recharge. Note:- Test results and settings are protected by a backup battery so these will not be lost. To start a Test, press the red button for at least one second. Two bleeps are sounded and the F, flashing test terminal indicator light, a
