Conversion of values from milliampere to ampere

Dear support,

we use the OpManager to monitor PDUs with a web-management over SNMP.

The PDU displays several values for power and amperage. The OpManager is
installed in the build 11600 and contains two PDUs. Here a following example
of my issue:

- I already create an own device template for the PDUs and created several
performance monitors to show values about the OIDs.

- Now i want to convert the amperage from milliamper to ampere, because
the OID for the amperage of the PDU will only display a value in milliampere.

- I already started to create a new performance monitor for the amperage of the
PDU and used the following formula "(OID)/1000" to get displayed the value in
ampere.

- Normally the value should be displayed now for example like this "0,8A". But i
will only show "0,0" in the performance monitor and it doesn't work to show
two decimal digits.

Is there a possibility to change it in the database of OpManager to get the correct
value displayed in the performance monitor with two decimal digits?

Attached you will find two screenshots about the configuration and the output
of the screenshot of the performance monitor.

Thank you very much for your help in advance and best regards,
Niklas
