Page 13: Operation
The circuit under test must be completely de-energized and isolated before test connections are made • The S1-5010 can generate up to 5 mA at 5000 V. Circuit connections must not be touched when testing. • When turned On, voltage in excess of 5 volts across the + and - terminals will be indicated on the display. -
Page 14: Performing Tests - General
Operation 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 check the operation of the measurement system and correct any small calibration errors which may occur during the life of the instrument. -

An internal fault occurs. When the test is terminated the item under test will be automatically discharged. • To return to the menu display and start another test, press the ‘Menu’ key. • To switch the instrument Off, press the On / Off button once. Auto switch-off operates after 10 minutes inactivity. -

8. To return to the menu display press the ‘Menu’ key. 9. If required, Setup the test button to the ‘NOT LOCKED’ position. Remote operation A software package S1-S1 is available for controlling the S1-5010 directly from a PC. You may also automatically define certain test sequences. See ‘Accessories’. -
Page 17: Test Mode Summary
Test duration is typically 30 or 60 seconds and the S1-5010 will allow you to set this duration, and the test will finish automatically. The reading will not necessarily be the maximum value but if the same duration is used each test, then the same point on the curve of increasing apparent resistance is being compared. -
Page 18: Dielectric Discharge Testing
Test Mode Summary The value of PI can often help in the situation where past test record frequency are limited, by giving a rough guide to condition of insulator. The figures should always be interpreted in the context of the equipment history and your experience. -

The maximum DD value that can be measured (assuming the default test voltage of 500 V) is typically 20, if the capacitance of the test sample is 1µF, but decreasing to 2 for a capacitance of 10 µF. If the maximum value has been exceeded the result will show a ‘>’... -

‘Batch’ (downloading a single or multiple results after a test(s) has been completed and stored in the memory of the S1-5010). In both cases, the download of results takes place via the RS232 port of the S1-5010 to a COM port of the PC. -
Page 21: Application Notes
Application Notes Preventive Maintenance The proverb ‘A stitch in time saves nine’ inspired the title of an Megger Limited booklet on insulation testing, as it neatly sums up the benefits of preventative maintenance. The savings come in financial terms from costly repairs, lost production, lost profits and in human terms, from lives saved in the event of dangerous electrical faults. -
Page 22: Insulation Testing Concepts
Application Notes Insulation Testing Concepts Insulation resistance can be considered by applying Ohm’s Law. The measured resistance isdetermined from the applied voltage divided by the resultant current, There are two further important factors to be considered. These are (i) the nature of the current through and/or over the insulation, and (ii) the length of time for which the test voltage is applied. -
Page 23: Test Techniques
The guard lead can be used to remove the effects of surface leakage if necessary. The S1-5010 is capable of measuring up to 5 TΩ, and down to 0,01 nA (equivalent to 500 TΩ at 5000 V). When measuring resistances this high, the test leads should not be allowed to touch each other or any other object since this will introduce leakage paths. -

(Please note that most voltmeters do not like more than 1 kV). If you wish to perform a proper calibration check using external resistors, the CB101 5 kV resistor box with 10 MΩ, 100 MΩ, 1 GΩ and 10 GΩ resistors is available from Megger Limited. -
