Important: always send the final FRA2CAL.INI (for the FRA2 module) or the determined C1 and C2 values (for the FRA32M module), together with the serial number of the instrument to Metrohm Autolab by email ([email protected]). This is important for future service. If not sent back, Metrohm Autolab will not be able to service this instrument properly.

15.2 – No calibration possible

If you do not have a Faraday cage or if you are not able to calibrate, you can fill in the typical values for C1 and C2 given in Table 2. This will however affect the accuracy of the measurement.

Instrument type C1 C2

PGSTAT30 1.6E-11 5.0E-13

PGSTAT302 1.6E-11 3.0E-13

PGSTAT12 2.6E-11 1.0E-12

PGSTAT100 1.6E-11 5.0E-13

15.3 – Verification of the calibration of the FRA module

A dedicated test for the FRA module is provided in NOVA. Please refer to section 16 for more information on the testing of modules in NOVA.

The calibrated module must pass the described test. If the values are out of range, something is wrong with the installation or with the calibration. Please check the complete installation procedure. If re-calibration is necessary, please remember to set C1 and C2 values back to zero in the Hardware setup of Nova.

16 – Module test

After installation of the module, the following tests should be taken to verify that the module is working as expected:

1. Connect mains power. 2. Switch Autolab on. 3. Install the delivered software if necessary (please refer to Table 1 for the software

version requirements for each module). 4. Select Hardware setup and activate inserted module.
