I have tried your scaling files, well the first 4, I copied them into a file and saved it as user.psc.
I then opened Enviromon and configured the equipment, so that the EL037 was found.
I then went to location and added a channel, in the 'Sensor Information' window where a channel is configured I did the following:
Set the channel up. eg. 1 - 4 for an EL005, 1 - 3 for an EL008
Set the convertor to: 4-20mA
Then in the Sensor dropdown box you will find all the sensors you have created. eg. sINK1, sINK2, sINK3 etc.
Your scaling files are fine and work correctly.
