VIP 4000RESISTIVITY & IP 4 kW TRANSMITTER • 3000V output voltage • Full microprocessor control • Ease-of-use • Standard motor generator The VIP 4000 is a four kilowatt current regulated Time Domain Induced Polarization transmitter. |^IP4000^AJOR^ENEFIT^^^| • Light in weight and provided with a high voltage (3000V) output, the VIP 4000 is particularly convenient for IP surveys in high resistivity rugged areas and for deep resistivity soundings. • Microprocessor controlled for ease of operation and protection against misuse. All injection parameters (current, voltages, ...) are controlled. The VIP 4000 can also be operated through its remote control port (RS232). • The VIP 4000 eight output dipoles provide for higher productivity in the field. Powered from a standard single phase motor generator, the VIP 4000 eliminates the maintenance and supply problems associated with custom power sources. HIGH OUTPUTS: • The VIP 4000 will generate up to 3000 volts for work in high resistivity areas and up to 5 amperes at 800 volts for low resistivity regions. With its weight of only 16kg, the VIP 4000 is the lightest 4000W unit on the market. FULLY AUTOMATED: • The VIP 4000 is designed for ease of operation. It has a much simplified front panel: current, dipole and frequency (in the frequency domain) settings are the only parameters to be selected by the operator. All the other functions, like voltage range setting, are fully automated. PROGRAMMABLE: • Programming functions are also available, either through the front panel, with a special key combination, or from an external computer terminal. 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 also increased. For example, it is not possible to switch dipoles when transmitting. This eliminates the possibility of burning out the selector switch or the output circuitry. HEAVY DUTY DESIGN: • Very high quality connectors, and heavy duty industrial components are used throughout. The VIP 4000 is shock resistant and weatherproof, for a higher reliability.

COMPLETE DISPLAY: A back- lighted liquid crystal alphanumeric display is provided for the simultaneous indication of all output parameters. Output current, output voltage, contact resistance and output power are continuously displayed. ERROR MESSAGES: Messages and warnings are displayed in case of problem or malfunction. Besides, the permanent storage of all the parameters relating to the operation of the unit make easier the remote identification of a trouble by the manufacturer for quicker instrument servicing. INTELLIGENT REGULATION: The VIP 4000 internal microprocessor is capable of excellent...
