Typically, these testers are used to take a series of
measurements over a period of time which will show the
gradual decline that takes place in the insulation during its
operational life. Such monitoring enables the user or to
anticipate future performance and to plan ahead for
repairs. They are also used to show improvements in the
insulation of motor, transformer and generator windings
that result from drying-out procedures used after exposure
to excessive humidity or water.
FEATURES AND BENEFITS
• Guard terminal to eliminate surface leakage current
• High-resistance readings up to 20,000 MΩ (analog
• Digital autoranging with readings up to 1999 MΩ (digital
• Multiple test voltages
