The instrument is microprocessor controlled and features a large, clear LCD combining digital and analogue readings of insulation resistance.The digital full scale of 5 T can b

12、e set to display leakage current instead of resistance. In this mode of operation, higher resistances can be measured. The S1-5001 has selectable test voltage options of 500 V, 1000 V, 2500 V and 5000 V. A variable output voltage setting provides a range of 25 V to 5000 V incremental in 25 V steps.

13、At switch on, the instrument carries out a calibration self check which automatically adjusts the measurement system. The calibration sequence inhibits any testing if the measurement system fails to meet preset limits. On starting a test, the HV warning LED on the front of the instrument flashes, to

14、gether with the display HV warning symbols. The integral timer starts automatically and displays minutes and seconds elapsed since the start of the test. The timer can be used to set the duration of a test, and will automatically stop the output voltage when the set time has expired. Battery capacit

15、y is continuously displayed by a segmented indicator. The indicator flashes when the battery requires recharging. Power is obtained from two parallel connected sealed rechargeable lead acid batteries. If either battery fails (or an internal protection fuse ruptures) the instrument will continue to o

16、perate on the alternative battery. The battery is recharged by external 95 - 265V a.c., 50-60 Hz, or 12 V d.c.supply. Test Mode Summary 5 Insulation Resistance Testing (R) This mode measures insulation resistance at the selected voltage to provide an instantaneous spot reading. Final test result is

17、given sequentially with the corresponding leakage current and capacitance value. Test Current measurement (I) This mode measures insulation at the selected voltage to provide an instantaneous spot reading, but displays leakage current value on the digital display. (N.B. The analogue scale always dis

18、plays resistance). Final test result is given sequentially with the corresponding resistance and capacitance value. Fault Conditioning (Burn) This feature is used to carry out continuous testing under breakdown conditions. General Notes: 1) Acapacitance value reading is only available if the test ha

25、charge the battery before the instrument is put into service for the first time. Charging is carried out by external a.c. mains supply, or by 12 V d.c. supply. A 12 V charging lead fitted with an automotive cigar lighter plug is available for charging the battery from a vehicle.Testing is inhibited

26、during charging. Mains supply re-charging Mains input recharging requires a voltage within the range 95 - 265 V a.c., 50 - 60 Hz. Disconnect the test leads and connect the mains supply to the IEC 320 connector in the charging recess. Confirm that the red indicator lamp is illuminated. Charging is au

27、tomatic as soon as the mains supply is connected. To fully recharge the battery takes about 16 hours. Eight hours charging (from a fully discharged state) will achieve at least 90% of full charge. Turn the instrument on and check the battery capacity indicator to show the state of charge. 12 V d.c.

28、supply re-charging This method of re-charging should only be carried out if a mains supply is unavailable as it is slower and less efficient. If using a vehicle as the charging source, the engine should be running. Observing correct polarities shown, connect the 12 V DIN socket to the external 12 V

29、d.c. supply and switch on. Caution: Applying more than 15 V to this socket will overcharge the battery. 12 V DIN socket (Viewed from front of panel). Battery Charging Notes 1)Do not leave battery in a totally discharged state. Frequent charging to keep the battery topped up will maximise battery lif

30、e. 2)Battery charging should be carried out in a dry environment (the IP54 environmental protection applies with the charging cover securely closed). 3)When charging the battery indoors, the area should be well ventilated. 4)The battery should only be charged at temperatures in the range 0 C to 40 C

31、. 5)It is beneficial to continue charging and no harm will occur to the battery if the charger is left on indefinitely. 6)If the instrument is idle for long periods, recharge the battery for at least 24 hours every 6 months.

37、 during a test. 3. The S1-5001can give an electric shock. Highly capacitive circuits (e.g. long lengths of cable) charged to several kV can create a potentially lethal charge. 4.Care must be taken to prevent capacitive circuits becoming disconnected during a test, leaving the circuit in a charged st

When carrying out prolonged tests unattended, care should be taken that no harm or damage can be caused. 7.When using the BUR

39、N feature, care should be taken that no harm or significant damage can be caused. 8.In certain circumstances, break-down of the circuit under test may cause the instrument to terminate the test in an uncontrolled manner, possibly causing a loss The circuit under test must be completely de-energized

The flashing red LED and the flashing H.V. symbols warn that a test is in progress. 7.When testing resistive or modera

41、tely capacitive loads (up to about 1F) the test voltage will appear within a few seconds. The test voltage is controlled to within 5% of nominal, adjusting itself for changes in resistance. The actual output voltage is displayed during tests. On large capacitive items the voltage rise will be notice

42、ably slower and on low resistances (less than 10 M) the voltage may never rise to its nominal value. 8.Insulation resistance readings are updated once every second for measurements up to about 100 M. For measurements between 1 G and infinity the sample frequency rate will slow to 20 seconds. 9.A tes

43、t can be manually aborted at any time by pressing the red test button. A test will automatically terminate if: - The set test duration is reached. - The insulation under test suffers a complete breakdown. - Excessive electrical noise interference (2 mA at 5 kV). - The battery becomes exhausted - Fus

Auto switch-off operates after 10 minutes inactivity. 9 Performing Tests - General 1.Switch the S1-5001On by p

45、ressing the On/Off switch once. All LCD segments appear for 5 seconds, then the word CAL appears for about 5 seconds. When the word CAL disappears, the instrument is ready for use, and in standby mode. Note: When not testing (i.e. in standby mode) the S1-5001 acts as a voltmeter. (50 V to 1000 V). 2

46、.Ensure that all test leads are clean and in good condition, and connect them to the isolated circuit under test. If an external voltage 50 V is detected the voltage is displayed together with high voltage symbols. 3.Select the required test mode using the Range keys to move the right hand cursor. 4

47、.Unless accepting a default test time, use the Selector keys to move the left hand cursor to the timer position and increment to the desired test duration using the Range keys. Setting zero time inhibits any testing. (Maximum test time is 90 minutes). 5.Use the Selector keys again to set the require

48、d test voltage. The variable voltage 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. To select, move the left hand cursor to the variable voltage position and adjust the output terminal voltage us

49、ing the Range keys. The voltage set is shown at the top of the display. When set to variable voltage, the test mode cannot be altered. Note: Changing the voltage during a test will temporarily alter the reading. A steady reading will appear when the new voltage Test Current measurement (I) This test mode measures insulation continuously at the selected voltage, but displays leakage current value instead of resistance. This enables even higher resistances to be calculated. Using this method it is theoretically possible to measure resistance up to 500 T at 50
