An Inverting and Non-Inverting Amplifier are configurations of an Operational Amplifier (Op-Amp) used to amplify input signals. The inverting amplifier produces an output signal that is 180° out of phase with the input, while the non-inverting amplifier preserves the input signal's phase. Both are widely used in audio, signal processing, and instrumentation systems.

Key Features:

Inverting Configuration: Output is inverted relative to input, with a phase shift of 180°.

Non-Inverting Configuration: Output signal remains in phase with the input.

Voltage Amplification: Provides controlled amplification of weak input signals.

High Input Impedance: Ensures minimal loading on the input signal source.

Low Output Impedance: Ensures efficient signal transfer to subsequent stages.

Adjustable Gain: Gain can be varied using external resistors.

Versatile Applications: Used in audio amplifiers, filters, signal conditioning, and voltage followers.

Fault Locator or Fault Finder is a device or system used to detect, locate, and diagnose faults or failures in various engineering systems, such as electrical networks, mechanical structures, pipelines, and communication systems. These tools are essential for identifying issues quickly, minimizing downtime, and preventing damage or safety hazards

The vt 395 handheld meter features sophisticated circuitry that produces

Higher accuracy than other pocket-sized meters.  This allows for the same

Advantages as megohmmeters, but at an economical price.

Utilizing color-coded zones, the led scale is easy to read and interpret. 

Half decade measurements give a closer indication to actual value.  A

Specially colored “warning” stage alerts the auditor to material

Approaching the upper end of the dissipative scale, so that it can be

Designated as nearly out of specifcation.
