  DJS-8BHigh Power IP Receiver

1.Rapid and Accurate: By adopting pulse delay synchronization mode and high-precision quartz clock synchronization mode, more accurate power-off delay is enabled , precise polarization measurement is realized , thus overcome the enlarging problem of apparent polarization error caused by large judgement error in power-off time for similar instruments.

2.Automation: SCM (Single Chip Micyoco) automatically execute self-potential compensation, gain adjustment, filtering and signal enhancement.

3.Time Parameter Recording: DJS-8B has auto travel time function, with measuring time stored together with measured results to facilitate the calculation of apparent resistivity.

4.Extra-large Storage: 15,000 groups of measured values can be stored, no loss even in case of power failure

5.Strong Anti-interference Capability: Adopt signal enhancement technology to suppress the interference a, thus highlight the effective signals.

6.RS-232C serial port can work with microcomputer (PC) on-line.

7.Fault Diagnosis: Fault location and damaged device can be accurately identified.
