pySartoriUSB

USB serial connection to Sartorius Scales

Example:

    import pysartoriusb as sub

    with sub.SartoriusUsb('COM4') as conn:
        result = conn.measure()

    assert result.mode == "G"
    assert result.value == "+3.4"
    assert result.unit == "mg"
    assert result.stable == True
    assert result.error == False
    assert result.calibration == True

Available Commands

There are two methods available to send commands to the scale:

• SartoriusUsb.send(cmd): just sends a command, results must be read programatically
• SartoriusUsb.get(cmd): send a command and return the answer from the scale

Since "printing" the current measurement and parsing the result is something very common, there is a simple method for it: SartoriusUsb.measure()

These commands are available:

• CMD_PRINT: "Print" the current measurement result

• CMD_TARA: performa a tara or set the display to zero

• CMD_EXPCLICIT_TARA: explicit tara only

• CMD_EXPCLICIT_NULL: explicit set display to zero

• CMD_INFO_TYPE: show scale type

• CMD_INFO_SNR: show serial number of scale

• CMD_INFO_VERSION_SCALE: show software version of the scale

• CMD_INFO_VERSION_CONTROL_UNIT: show the software version of the command and display module

• CMD_INFO_USER: display user and device id

• CMD_FILTER_ENVIRONMENT_VERY_STABLE: set the filter to "very stable enviroment"

• CMD_FILTER_ENVIRONMENT_STABLE: set the filter to "stable enviroment"

• CMD_FILTER_ENVIRONMENT_UNSTABLE: set the filter to "unstable enviroment"

• CMD_FILTER_ENVIRONMENT_VERAY_UNSTABLE: set the filter to "very unstable enviroment"

• CMD_KEYBOARD_LOCK: lock the keyboard on the command and display module

• CMD_KEYBOARD_UNKLOCK: unlock the keyboard on the command and display module

• CMD_KEYPRESS_PRINT: simulate a keypress on the command modules 'print' key

• CMD_KEYPRESS_CANCEL: simulate a keypress on the command modules 'cancel' key

• CMD_BEEP: make the scale beep

• CMD_ADJUST_INTERNAL: start internal adjustment

• CMD_ADJUST_EXTERNAL: start external adjustment with standard weights

• CMD_RESTART: restart the scale
