2.10.Measure soil resistivity.
2.11.Pylon measurement function(
2.7. With RS232 and USB interface
*PS.: RS232 and USB interface only for secondary development or improvement, can supply the Serial
Protocol, not provide the background software.
3. Technical breakthrough
3.1.Step voltage option can setting the current output time control, can set the constant current
output time as reqeust.
3.2.Storage uses keyboard input to convient query.
3.3.After step voltage testing, the voltage can input to print out.
3.4.Use external power supply mode can extand to the large current measurement
