Page 5: Introduction
EXD in a sine-wave for EIS. The EXD must be equipped with an analog control input port for connection with the FRA-X. The analog control input of the EXD should be in the range of ≤ ±10 V. -

(f > 1 kHz). To compensate for the usual slow nature of the EXDs, the EXD involved in the FRA-X setup is only used to output the sine-wave signal and the FRA-X measures the current and voltage responses in the device under test (DUT) itself via transducers. -

Fig. 1: Connection scheme of FRA-X setup The FRA-X is delivered with a voltage transducer from TESTEC which is powered up with a USB cable and a USB plug. The PAD4 card is optional in the FRA-X setup shown in Fig. 1. - Page 8 FRA-X...

Page 9: Setting Up Fra-X
FRA-X. Before setting up the parameter for the FRA-X setup, the EXD must be turned off or the output from the EXD must be turned off. By turning off the output of the EXD, you disconnect the DUT from the FRA-X and avoid possible damage to the connected DUT. -

4.1 Input signals 4.1.1 Current transducer Zahner offers multiple current ranges for the transducers. For a transducer, a suitable current-in gain [A_cell/V_acq] must be set in the Global Measurement Settings window. The default current-in gain values for different current transducers are provided in Table 1. - Page 11 FRA-X -10- 3. Pass one current-carrying cable from the power supply to the DUT through the current transducer. In the case of small currents, one may pass multiple turns of a cable through the current transducer to increase the accuracy of current measurement. In this case, the default current-in gain must be divided by the number of cable turns.

4.1.2 Voltage transducer Zahner offers multiple voltage ranges for the transducers. For different voltage ranges suitable voltage-in gains [V_cell/V_acq] must be set in the Global Measurement Settings window. The gains for each voltage range are provided in Table 2. - Page 13 12. Repeat steps 6 to 11 until the voltage output from the power supply and the Thales software match across a broad voltage range. The user must activate the Z-mode to see the correct current/voltage values in the FRA-X mode.

Page 14: Output Signal
-13- 4.2 Output signal For controlling an EXD via an FRA-X, one needs to set up the voltage- and/or current- out gains ([V_cell/V_ctrl] and [A_cell/V_ctrl], respectively) and offsets. The voltage- and current-out gains can be calculated from the equation below. -
Page 15: Saving Setup
EXD can only supply negative values. 4.4 Saving setup The user only needs to set up the gains, offsets and range for their FRA-X setup once. After setting up all the required setting parameters, the user can save the setting in the Global Measurement Settings by clicking on Save Preset. -
Page 16: Fra-X With Regatron Power Supply
Start the Thales software from Zahner and the G5.Control software from Regatron. Set the parameters for the FRA-X operation as it is defined in this manual. In the G5.Control software, the user needs to connect the device, and choose the I/O option so that the FRA-X can control the Regatron’s power supply.
