Page 2: Safety Warnings
SAFETY WARNINGS Safety Warning must be observed during use. The circuit under test must be switched off, de-energised, isolated and checked to be safe before insulation test connections are made. Make sure the circuit is not re-energised whilst the instrument is connected. Circuit connections must not be touched during an insulation test. -

The dielectric absorption ratio is automatically calculated if the corresponding timers are set. The S1-1054 can be powered from the mains supply or by its own internal rechargeable battery, which provides for at least 4 hours of continuous Either burn or breakdown selectable in insulation resistance mode. -

POWER LEAD AND BATTERY CHARGING Cleaning If the power lead supplied is not suitable for your mains connection, do not use an adaptor. Always use a power lead fitted with the correct plug. Disconnect the instrument and wipe it with a clean cloth slightly damped The instrument is fitted with a two-pin IEC60320 power inlet. -

- Test V Alternatively, screened leads are available as an optional accessory from Megger. The lead to the negative terminal is fully screened. The screen is plugged into the Guard terminal, diverting any stray leakage currents. This considerably improves measurements made with a floating output, where Ground the leads might touch each other or anything other than the test piece. -
