Product features
- Assembly data acquisition devices and multiplexer together in the
same case,which not only reduce the volume but also decrease the
weight, thus avoid errors caused by operating the devices
separately and due to inconformity of switch parameter settings.
- Maintain all functions of DUK-2A Multi-Electrodes Resistivity
Survey System and conventional electrical method.
- Add high and low current transform taps, add high and low input
impedance transformation tap, and improve the acquisition
capability of weak signals.
- Add storage and output functions for compensation SP voltage value.
- Adopt 16-bit A/D and 16-bit D/A, thus improve the discernibility
for measurement of collected data.
- Add the function for automatically detect grounding resistance
before each measurement; give directions for the points exceed the
grounding resistance value, for automatically proceeding with
further measurement if required; the value at such point can be
replaced with a fixed symbol to facilitate the elimination of this
point while processing the information and data.
- Greatly enhance the repeatability of measured data.
