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.

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.

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.
