Multilog Application Guide
Configuring the N4L PPA Power Analyzer for
Data logging
The Multilog (MULTIL) command provides an excellent
method for data logging up to 64 parameters of
information via one query command - MULTIL?
The instrument will return a comma-separated string
which relates to the MULTIL,X,X,X setup commands
previously entered by the relevant communication method.
This enables the system to send one query and return up
to 64 different parameters, from different phases in one
response.
Step 1.
Reset “MULTILOG” using the MULTIL,0 command
This will clear any previously entered Multilog parameters
and ensure the instrument does not return unwanted
results.
Step 2.
Set up the Multilog parameters
The format of the Multilog command is as follows
MULTILOG, Index, Phase, function
Index is the order in which the value is returned
(Effectively allocating a “slot” for the parameter in the
returned string)
Phase is the phase (PH1,PH2,PH3 etc) from which the
result should be acquired.
Function is the parameter type (eg. Watts, VAr, Frequency
etc) of the return.
