Terminal communication

RS232, USB/RS232 or Bluetooth/RS232 communication with text command enable the easiest way to control all functions of the C300B in any system. If you want to use C300B calibrator in your own test system it will be fast and easy - just use the terminal.

To set 3-phase basic setting like voltage, current, angle and frequency, send commands:

RU_3,1,1 // voltage ranges 1-70V, 2-140V, 3-280V, 4-560V
U_230.000,60.0004,1.00000 // voltage values [V]
RI_1,3,4 // current ranges 1-0.5A, 2-6A, 3-20A, 4-120A
I_0.500000,10.2400,100.000 // current values [A]
FR_50.000 // frequency value [Hz]
FA_10.00,20.00,30.00,120.00,-120.00 // phase angle and angle between voltages [°]
STB_0,0,0,0,0,0 // U1,U2,U3,I1,I2,I3 1-standby/0-operate
