5.7.6 EXAMPLE OF VOLTAGE and CURRENT MEASUREMENT QUERY
How to query the UPC for three phase RMS volts (Line to Neutral) and RMS current metered values.
LINE to LINE volts, KVA, KW, Power Factor, CURRENT Crest Factor, and Peak Current may also be
queried in the same way.
See the
:FETCH
command and example for obtaining metered waveform data.
Step A. Address the UPC as a listener.
Step B. Select Voltages A,B,C and Load Current A,B,C for AC-RMS
query by sending the following command.
:MEAS:VOLT1;VOLT2;VOLT3;CURR1;CURR2;CURR3?
<eos>
NOTE:
<eos> is a LINE FEED (0Ahex, 10dec).
All parameters will be measured simultaneously upon receipt of the :MEAS: command. This may take
several hundred milliseconds depending upon Frequency and other factors. The values are not stored in
the UPC and another :MEAS: command will re-measure the values, further delaying response.
Step C. Address the UPC as a talker to read back a query response
string, similar to the following example, representing the three voltages
and currents.
120.2,120.3,121.0,3.2,2.9,3.0<eos>
Step D. Un-address UPC.
