Pyserial Issues with Python3.7 and Fluke Multimeter

[jfisher930]

Thank you Larz60+, i will be sure to correctly post in the future. Here is the error i am seeing.

Error:
Traceback (most recent call last):
  File "C:\Users\JeffF\Desktop\Python 3.7\Fluke 8846A Mesurement.py", line 18, in <module>
    ser.write('SENS:VOLT:RANG 10 \r\n')
  File "C:\Users\JeffF\AppData\Local\Programs\Python\Python37\lib\site-packages\serial\serialwin32.py", line 308, in write
    data = to_bytes(data)
  File "C:\Users\JeffF\AppData\Local\Programs\Python\Python37\lib\site-packages\serial\serialutil.py", line 63, in to_bytes
    raise TypeError('unicode strings are not supported, please encode to bytes: {!r}'.format(seq))
TypeError: unicode strings are not supported, please encode to bytes: 'SENS:VOLT:RANG 10 \r\n'

Looking up this error it seems that i should be using the following:

ser.write('SENS:VOLT:RANG 10 \r\n'.encoder())

but using this function causes an endless loop after the time sleep command
