To read features maximum number of timers:
operreg = localnode.define.MAX_TIMERS
Use to read power line frequency detected at power up.
To read line frequency:
frequency = localnode.linefreq

To achieve optimum noise rejection when performing measurements at integer
NPLC apertures, the line frequency setting must match the frequency (50Hz or
60Hz) of the AC power line.

When used in an expanded system (TSP-Link), localnode.linefreq is sent to the
Remote Master node only. Use node[N].linefreq (where N is the node number) to
send the command to any node in the system. See for details on TSP-Link.
To get the line frequency:
print(localnode.linefreq)
Use to query model number.
value = localnode.model
value: Represents model number.
To print model number:
print(localnode.model)
Output:
3700S
