Gain Lock

I use current loop (L) sensors with 100 ohm shunt, with 4-20 mA range. I have also set gain lock to 2V since the voltage over the resistor will be in the range 0,4 - 2V. Is it possible to get readings of over 100% if the signal reaches beyond 20mA?

If this is the case approx. how much "over-range" is allowed before the error indicator (99999) is returned?

Good afternoon baidarabj,

There will be a little over range but not much. I would not allow for any over range to be safe.

Cheers,

Thanks Roger,

do you think it is possible to get some indication on the limit?

Good morning Bertil,

The upper limit will vary somewhat between loggers due to the various tolerances of the individual components.
I will have to do a number of tests to establish a typical figure.
I'll add it to the list of jobs and will get back to you as soon as I can

Cheers,
Roger
