Precaution
·Please read the notes and user's manual carefully before operation.
·Before measurement, please ensure that the mainframe and the tablet PC have power. If the battery is not enough, it should be ·recharged to avoid affecting the measurement.
·Prohibit misconnecting A, B, M, N ports and DC high-voltage port (DC HV+ and DC HV- ).
·WDDS-3C has built-in high-voltage battery and external DC high voltage for option. When usingthem together, the instrument will choose the power source with higher voltage.
·WDDS-3C built-in high-voltage power supply output current is small, the supply current should notexceed the maximum working current 300mA when using, if the supply current IP is greater thanthis value, please reduce the voltage of the DC high-voltage power supply.
·If system clews "Current supply is too large...", please turn off the mainframe to inspect whether AB is short-circuited or DC over-voltage.
·If system clews "A(B) current open circuit...", please turn off the mainframe to inspect whether AB is short-circuited or DC over-voltage.
·If the indicator light of built-in high voltage in WDDS-3C flashes, please exit measuringand turn off the built-in high voltage power source to inspect if the current supply istoo large or the instrument is over-temperature.
·DO NOT turn off WDDS-2C/3C or break off any connection during working.
·For 2P or 3P survey, the infinite electrode connect with "B(∞)"
·If the electrode array is 3P-PREL or 3P-VES, the infinity electrode should wiring B(∞) terminalsand transmitting of B electrode wiring B(3-pole).
·For new survey line, please set all working parameters correctly before measurement.
·The effective distance of Bluetooth communication is 10 meters, if exceed 10 meters, the communication fails and the Bluetooth needs to be paired again.
·The instrument should not be stored in humid or corrosive gas environment for a long time.
·DO NOT have the instrument work in or stared where the temperature is lower than -20ºC.
·The mainframe is not waterproof; DO NOT put the instrument in moist or gas-erosive environment.
·If the instrument is not to used for a long time, charge the lithium battery every 3 months, or the battery will be damaged.
