I wish to add custom dial with Fan Status

I found the OID Object : .1.3.6.1.4.1.43.45.1.10.2.6.1.1.1.1.19.10

In the MIB browser works fine:

h3cEntityExtErrorStatus.10:-->fanError(41)

When I add the monitor in my device template how can I add in the units field to see the status like an error?

If I add % I see the status green with 41% value

Thanks
