    Measuring Frequency Measurement MC4 measures frequencies between 0.0027 Hz (10 cph) to 50 kHz. Frequency Measurement Function: Trigger Level Also check the setting. There you can specify the trigger level and whether to use a test voltage during the frequency measurement.

  • Page 55: Pressure Measurement

    Pressure Measurement Pressure Measurement MC4 supports the use of an internal pressure module (if installed). When connecting an external pressure module to MC4, it is automatically detected and there is a possibility to immediately put the connected external pressure module to use.

  • Page 56: Connecting And Disconnecting External Pressure Modules

    An external pressure module may be connected and disconnected at any time. If a removed module was part of an active measurement, MC4 emits a "bleep" to inform you of the fact that the external pressure module used for pressure measurement was removed. The window where the external pressure measurement was configured reverts to "None/No Function".

  • Page 68: Current Generation

    Generating/Simulating Current Generation MC4 is able to generate current both in source and sink mode. In source mode MC4 provides the supply power to the loop. In sink mode an external power supply is used and MC4 controls the current flow.
  • Page 69 Make sure that you don't exceed the maximum current allowed by the instrument under test. If you open the current generation loop, MC4 tries to maintain the current by increasing the output voltage. If you then close the loop again, the current is first too high, but returns quickly to the correct level.
