Measure control panels:

Measure control panel

This controls the modules that are placed in the measurement-slots. These 2 (identical) slots are located left to the dual iso-amp output. The switches only control logic lines to the module where solid state or relay switching of the real signals takes place. The switch lines are in each module galvanically isolated from the signal circuits.

Panel Layout:
Version2:(as drawing) Text around switches is labelled for standard modules
For M1 (current meas.), switch functions are as mentioned on the right side of the knobs. For M2 (voltage meas.), read functions at the left side.

Underneath each control/readout a general name (F1,F2 etc) is given as a reference for new modules in which the controls can have other functions. For each module an control implementation is given which refers to the general names.

Version1:(as picture) Text around switches is labelled for standard modules ,red=M2 (voltage measurement), green=M1 (current measurement), black=both Development of additional modules still goes on, so when using other (special) modules, text on controls may not match to module functions, corresponding functions-switchsettings are mentioned on the front of that modules. Some modules have their own control switch on the front, this is because of technical convinience (e.g. the gain switch on the Tohm 5fA amplifier)


Source control panels:

Source control panel

This controls the modules that are placed in the source-slots. These 2 (identical) slots are located to the right of the iso-amp input. The switches only control logic lines to these module where solid state or relay switching of the real signals takes place. The switch lines are in each source-module galvanically isolated from the signal circuits.

Some source-modules have control switches on the module itself, manual control is mentioned in their description.

Panel Setup:

Version2:(see drawing) Text around switches is labelled for 2 standard modules
For S3 (voltage source), switch functions are as mentioned on the left sideof the knobs. ForS4 (current source), read functions at right side of the knobs.
The LED (max) indicates internal clipping in the current source S4 but can have other functions for different modules
Underneath each control/readout a general name (LED=D1, gain=G1..G7 etc) is given as a reference for new modules in which the controls can have other functions. For each module an control implementation is given which refers to the general names.

IVVI-DAC: 2xSource1xMeasure control panel

This controls the modules that are placed in the source-slots. These 2 (identical) slots are located to the right of the iso-amp input. One measure slot is also controlled (next slot following source 1/2). The switches only control logic lines to these module where solid state or relay switching of the real signals takes place. The switch lines are in each source/measure-module galvanically isolated from the signal circuits.

Some modules have control switches on the module itself, manual control is mentioned in their description.
