Page 8: Operating Instructions
A range of test voltages for insulation resistance tests up to 5 kV (S1-568), 10 kV (S1-1068) and 15 kV (S1-1568) are available, including a user selectable voltage range which can be set between 40 V and 5000V or 10000 V or 15000 V depending on the model. -
Page 9: Breakdown Vs. Burn Mode
Breakdown vs. burn mode For further explanation see, “Running an Insulation Test” on page In breakdown mode insulation tests are automatically stopped when a fault causes the applied voltage to drop rapidly. Burn Reset Default Settings mode IR tests ignore breakdown and continue to test the insulation and are therefore destructive tests. -

The setting does not change even if the instrument is switched off. Initial setup It is important to setup the Real Time Clock (RTC) on S1-568 and Alarm setting S1-1068 to ensure that records saved in the instrument are A low resistance alarm can be set to sound when the resistance of time/date stamped correctly. -

In the breakdown mode the breakdown icon will be indicated. The S1-568, S1-1068 and S1-1568 have been designed to handle high noise currents up to 8 mA. If currents above 8 mA are detected, In breakdown mode the test will automatically terminate on detection of a breakdown to prevent damage to the insulation. -
