Safety Warnings 1. Safety Warnings The safety instructions given in this document are indicative of safe practice and are not be considered exhaustive. Additionally, they are not intended to replace local safety procedures in the region where the instrument is used. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
All test leads, probes and crocodile clips must be in good order, clean and with no broken or cracked insulation. Verify the integrity of the test leads before use. Only “Megger” approved test leads must be used with this product. The safe maximum limit of a measurement connection is that of the lowest rated component in the ...
The warning will not operate if the instrument is set to Off. Internal Error Warning Internal Error Warning switch off and bACk on. Contact Megger if not cleared. Read the User Guide Refer to the user guide if this message shows.
In addition the IMT100 also incorporates temperature measurement and compensation (for Insulation Resistance and DLRO tests), direction of rotation plus supply phase rotation tests. All these new test abilities go together to make the IMT100 a real world, versatile, hand held test instrument for rotating machinery.
