READ_MEASUREMENT_DMM7510

Reads a single measurement from the DMM7510. Requires a CONNECT_DMM7510 block to create the connection. Params: connection : VisaConnection The VISA address (requires the CONNECTION_DMM7510 block). Returns: out : Scalar Measurement

Python Code

from typing import Optional

In this example, a DC voltage measurement was extracted from a Keithley DMM7510.

First the necessary blocks were added:

• CONNECT_DMM7510
• RESET_DMM7510
• FUNCTION_DMM7510
• DIGITS_DMM7510
• MEASUREMENT_PARAMS_DMM7510
• MEASUREMENT_FILTER_DMM7510
• READ_DMM7510
• BIG_NUMBER

The instrument address was set for each DMM7510 block. The FUNCTION_DMM7510 block was changed in order to extract the correct measurement. The parameters in DIGITS_DMM7510, MEASUREMENT_PARAMS_DMM7510, and MEASUREMENT_FILTER_DMM7510 blocks were changed as necessary. The READ_DMM7510 block was connected to the BIG_NUMBER block in order to view the reading.

The blocks were connected as shown and the app was run.
