Current Monitoring:
The typical 0 to ±10 V (full-scale) current sense signal output by the electronic load
or programmable power supply is shown as “Imon” in the block diagram of Appendix C. “Imon” is fed by a
coax cable to the LPI D-sub Module where it is divided down to 0 ±0.100 V (full-scale). This signal is then
fed into the Work Electrode pin of the Interface 1010 cell connector.
Voltage Monitoring:
The DUT terminal voltage is divided down in the LPI Cable End Module using resistor-
capacitor networks. The dividers ensure that the voltage out of the LPI Cable End module equals ±10 V at
the full-scale rating of the LPI cable. For example, the 1 kV LPI cable divides the DUT voltage by 100 and
the 10 V LPI cable divides it by 1. This 0 to ±10 V signal (full-scale), shown as “LV” in the block diagram of
Appendix C, is fed by a coax cable to the LPI1010 D-sub Module. The “LV” signal is buffered by unity-gain
amplifiers in the LPI D-sub Module and fed differentially into the Reference Electrode and Work Sense
Electrode of the Interface 1010 cell connector.
Install the Interface 1010 potentiostat
The LPI1010 is used with the Gamry Instruments Interface 1010E Potentiostat/Galvanostat/ZRA. Follow the
installation instructions in the Interface 1010 Operator’s Manual (988-00063). The current version of this manual
can be downloaded on Gamry’s website at
https://www.gamry.com/support/documentation-downloads/
.
Install the LPI1010
1)
Ensure that the DUT is not connected to anything
2)
Verify that both the Interface 1010’s Power switch is turned OFF and the electronic load or programmable
power supply is turned OFF
3)
Connect the LPI1010 D-sub Module to the Cell Cable connector on the Interface 1010’s front panel, as
shown in Figure 4-2

4)
Hand-tighten the jackscrews of the LPI1010 D-sub Module until they are snug.
Please refer to the Interface 1010 Operator’s Manual for detailed information about
connections, speficiations, and general usage.
