VIP
This device (VIP) is considered to be the strongest device used to search for gold and treasures in the world. It has highly sophisticated features that fit both the soil and the climate of the Middle East.

Features and Characteristics:

- Up to 3000V, 10A.
- Standard motor generator.
- Easy to use.
- Full microprocessor control.

VIP MAJOR BENEFITS:

- VIP is light in weight and endowed with a high voltage
  output (3000V):this is particularly convenient for IP
  surveys in high resistively rugged areas and for deep
  resistively sounding.
- VIP is powered from a standard single phase or three phase
  motor generator: this eliminates the maintenance and supply
  problems associated with custom power sources.

VIP MAIN FEATURES:

1-HIGH OUTPUT:

-In medium and high resistively areas, the amount of current driven into the ground depends on the maximum output voltage provided by the transmitter; in addition in low resistively areas, it is also dependent on the maximum output power.

The VIP features the following specification:

- High output voltage: 3000 V
- High output power: 5kW
- High output current: 10A

2-HEAVY DUTY CONSTRUCTION:

Very high quality connectors and heavy duty industrial components are used throughout. The VIP is shock resistant and weatherproof, for a higher reliability.

3-FULLY AUTOMATED:

The VIP is designed for ease of operation. It has a much simplified front panel:
Current setting is the only parameter to be selected by the operator. All the other functions, like voltage range setting, are fully automated.
 
 
4-PROGRAMMABLE:

Programming functions are also available through the front panel, but with a special key combination. These functions are used to select the parameters and options that are not normally changed during a survey: operating mode, time or frequency domain, cycle time, frequencies. This approach reduces front panel cluttering and drastically reduces the possibility of operator mistake. Instrument reliability is thus increased.

5-STANDARD MOTOR GENERATOR SUPPLY

Ion order to minimize transportation and maintenance costs, the local availability of a motor generator is a key factor. Being powered by a standard motor generator, the VIP offers the highest flexibility in its class. Its power input requirements are:

- 180 to 250 V voltage for maximum output power
- 45 to 800 Hz frequency
- Single phase or three phases
- Motor generator or power line supply

6-FULL MICROPROCESSOR CONTROL
 
The full microprocessor control of the VIP allows the following basic benefits:

- Ease of use through interactive menus
- User friendly selection of the current value
- Continuous display of output current, voltage, power, ground
  resistance values
- Display of intelligent messages and warnings in case of a problem
  or malfunction: overload, short circuit, input, under or over voltage.
 
 
7- INTELLEGENT REGULATION:

The VIP internal microprocessor is capable of excellent current regulation in almost any load. Current may be selected by operator in preprogrammed steps from 50 MA to 10 A. intelligent are always in operation. For example, the contact resistance will occasionally be too high for the VIP to provide the requested current setting. In such cases, the VIP will display a warning message and will set the current to the maximum value allowable under that combination of current setting and contact resistance. Some reserve current capacity will always be kept to insure that the current stays constant during the measurements, even with some contact resistance fluctuations.

8-COMPLETE DISPLAY:

A back-lighted crystal four lines alpha-numeric display is provided for the simultaneous indication of all output parameters. Output current, output voltage, contact resistance, and output power are continuously displayed.
