Documentation:
The keithley 2701 is a multichannel multimeter with a socket interface. Different kind of thermocouples measuring, voltage, current, resistance and frequency are possible. These macros have been tested only with thermocouples of type K and 4-wire pt100. Even if the code could, in principle, support other types of measuring, precise configuration may be necessary. This device is not recommended for fast measuring. At the ESRF an alternative solution is to use wago modules. Typical overhead measuring times for a Keithley 2701 are around 200 ms for one channel, around 400 ms for a three channel configuration compared with just a few ms for wago modules. Nevertheless this device presents at least two advantages. One is the flexibility and easyness of its setup. The second one is that some features are available that are not available with wago: for example, the higher accuracy obtained with a 4wire pt100, instead of only 3-wire supported by the corresponding wago module. The keithley tcp/ip socket connection is a single client connection. This would, in principle, stops several application configuring measuring channels on the device at the same time as only one can have an open socket to the device. It is possible to have a multi-client setup by using a Socketserver proxy device server (check your bliss contact to set it up). Nevertheless, as clients may have different measuring configurations, a conflict could quickly arise. Multiple clients MUST use exactly the same channel configuration.

Macros:
Usage: k2701setup cntlname device Defines a keithley 2701 controller in the system. Parameter ident is an arbitrary name to identify the controller later. Parameter device can take two forms: The socket naming is simple and does not require any extra software on the other hand k2701 devices only support one simultaneous client to talk to it. If you want to have it configured at the same time in more than one spec application or GUI, the second option must be used. For this it is necessary to run a tango server that needs to be configured and started beforehand. k2701add Usage: k2701add <mne> <ctrl-ident> <ch> <readtype> Add a counter on one Keithley 2701 controller previously defined with k2701setup Parameters are: k2701init Usage: k2701init Initializes controllers. Includes a reset after configuration k2701show Usage: k2701show Not implemented yet | ||||||
