12.9 Checking the performance of the 795x If you want to check that the external connections are working properly, the Health Check facility can help you. It
shows, for each external connection:
• the name of the input or output
• the value of the data
• the units for the data
• whether the data is live or set
• the Modbus or location ID, or nothing.
If the data is live but the value appears to be unusually high or low, this may be because the external connection
is not working properly.
12.10 Giving your 795x a tag number If you have more than one 795x you may want to give each instrument a tag number so that, in printed reports
for example, you know which one the report refers to.

3. Input the identifier you want. This over-types any existing identifier.
