Keithley 2001

The Keithley 2001 is a digital multimeter.

Configuring the IOC

  • To configure the IOC, the user needs to set ACTIVATE_CHAN_%d macros to 1 in the client or globals.txt. In the macro, %d is a two-digit, zero-padded number between 1 and 10, e.g. 01, 05 or 10.

  • If one channel is activated, then the device reads the value using a single-shot protocol. If more than one channel is active, it scans through all of these channels quickly intern with a delay. The delay between scans is specified by the SCAN_DELAY macro in seconds.

Limitations of the IOC

  • The IRIS OPI and IOC macros are configured to allow the user only to activate channels 1,2,3,4,6,7,8,9.

  • The IOC is configured to only read DC voltage using the VOLT:DC measurement functions. This is the default behaviour of the device after the reset command, *RST, has been sent.

  • The OPI is designed to allow to view readings, view error messages and code, and reset the IOC in case the IOC gets into an error state.

Troubleshooting

  • If there are any problems, try clicking the “Reset IOC” button on the OPI.

  • If the device is not scanning on any channels, check that the IOC macros have been set in either the client or in globals.txt.
