USING AN SNMP PARAMETER AS A METER CHANNEL SOURCE
“Set by SNMP” has been selected in the Source dialog shown above. Clicking the Browse button invokes the
AutoLoad Plus
to identify the desired source parameter for the selected channel. If
the identified parameter is an integer, the MIB browser automatically populates the correct scale factor in
the Multiply by drop-down box. The final calculated result based on a retrieved test value can be displayed
by clicking the Calculate Value button. If desired, the scale factor used in the calculation can be manually
adjusted by changing the value in the Multiply by box.
In certain cases, a manufacturer may specify a MIB parameter with an integer data type when it is actually a
floating point number. This is to overcome an inherent limitation in the SNMP data formats. Usually in these
cases the text description field will include an indication such as “Type: float”. For this type of parameter,
the IEEE Float button can be manually selected to force proper interpretation of the retrieved value. The
Calculate Value button can be used to verify correct interpretation of the data.
