The alphanumeric display clearly displays measured and computed parameters. Direct access to measurements and display scrolling is available through a single key. The MS-716’s flexibility enables a high degree of adaptability inside the instrument package. Numerous hardware inputs and outputs can be “soft” allocated to accommodate a range of typical application requirements. While configuring the instrument, the user “soft chooses” the use of each input/output.
Through a menu setting, the isolated analog output may be set to track volume flow, corrected volume flow, mass flow, temperature, or density. This approach is capable of assigning the majority of hardware functionality.
The user can configure the standard RS-232 Serial Port for data logging, transaction printing, or remote meter reading through a modem connection. During system setup, a service or test mode is available to aid the user by monitoring inputs, exercising outputs, and publishing the system configuration.
