Appendix D: Power LED Blink Codes

In the rare event that some electronics module fails, we include the start-up blink codes that the blue Power
LED flashes. Upon start-up, view the Power LED. If it blinks more than five times, or flashes one of the blink-
codes below, please call Gamry Instruments for service.

Normal Start-up

The Power LED flashes three times.

Failure in an electronics module

The Power LED flashes codes depending upon the failed module:
Problem
Post SDRAM unidentified problem
Post SDRAM size error
Post ROM checksum error
Post Serial init. RX buffer
Post Serial init. TX buffer
Post Serial init. UART
Post Communications module missing
Post Control missing
Post potentiostat missing
If there are multiple problems, the communications board takes code priority over the memory module.

Severe problem

The red LED, which normally switches off after a rapid boot-up, remains illuminated.
If you receive one of the above codes, please call Gamry Instruments Service Department for
assistance.

Error Messages and Limitations

The Interface 1000 has a subtype, Interface 1000T, which may generate error messages under certain run-time
conditions:

Error Message This instrument is not authorized for Freq=

The Interface 1000T is able to perform EIS at frequencies 20 kHz or lower. Higher frequencies generate this
error message. Decrease the upper frequency to continue.

Error Message This instrument is not authorized for IERange=

The Interface 1000T is able to operate at currents of 100 mA or lower. Higher currents generate this error
message. Decrease the current to continue.

Error Message This instrument is not authorized for ScanRate=

The Interface 1000T is able to scan at rates of 1 V/s or lower. Higher scan rates generate this error message.
Decrease the scan rate to continue.
