Hello,

I have been using it as signal injector, it worked fine giving out voltage, current and temperature output until last week, I don't know how but I blew the fuses, I have changed the fuses. Now it gives voltage and temperature signals, but not current!!!

I set it as 4-20mA current source, but the output is zero amp when I tested it with my voltmeter. When I connected the signal injector into the socket for pressure transmitters, it keeps flashing "OL" on the device, and the controller on the front panel is not giving out any reading, I know for a matter of fact that the loop is fine, because I tested the loop before the Fluke device starting playing up.

I don't know what's wrong, it's really frustrating, please help.

Please Help.
Thanks !

I didn't find the right solution from the internet.
