Parse clean up data first then load into dataframe,a common way is to use regex with this.
Example.

data = '''\
PO_UI{DC volt
Current IR
Density mass kg
}PO_UI
****************************
Type of cell
Current mode
Voltage
*******************'''

>>> import re 
>>> 
>>> r = re.findall(r"\{(.*)\}", data, re.DOTALL)
>>> r
['DC volt\nCurrent IR\nDensity mass kg\n']
>>> 
>>> print(''.join(r).strip())
DC volt
Current IR
Density mass kg
