Isolation Measuring Device (IMD)

The IMD is a device for isolation measurement in Flying Probe Testers for PCBs.

The IMD is perfectly driven and controlled by the FourStars-ES ProbeStar Software.

The main functions of the IMD is:

• High Resistance measurement up to 10 G-Ohm ( 10000 MOhm)

                            IMD     (modified picture sharpness to save IP)

The IMD contains:

• Power connector for single 24V DC supply
• Local voltage regulators
• References
• High voltage generator
• High voltage n-/p-channel switches
• Analog components (converters, amplifiers, etc. )
• Interface to the measuring probes
  max. cable length to contacting probes: 8 m each
• USB-Interface to the controlling PC

Specification:

• Resistance Measurement:
  • Test-Voltage 50V <= voltage <= 1000V
  • 10kOhm <= resistance <= 10 GOhm
  • Auto ranging   (5 discrete ranges)
