There are 6 connectors in Working Standard (WS) body, located top and bottom.
These options divide all accessories into 4 categories:
Charging (connector: +12V)
-
device is battery operated, which means that after any work the WS should be charged
Communication (connectors: USB, RS-232)
-
WS measures and stores all data, each meters is saved in internal database. This data can be
downloaded into master PC
Measurement of power variables (connectors: In A, In B)
-
Device can measure wide spectrum of electrical variables such as voltage, current, angles,
power factor, powers, energies, ratios, ... and for that purpose various combinations of
current and voltage probes ca be used.
Error measurement and signal output (connector: Aux)
Optical scanner provides meter's LED capturing and disk revolution gathering. On the other
-
hand WS can be easily checked by other reference meter using proportional frequency output.
Measurement is carried out in real time. There are several screens available right after device is
turned on. The number of screens is influenced by connected probes.
For testing voltage, current and optical sensor is needed. For disk meter calibration is also required in
advance. Any test results can be saved in the database.
Situation: Connection system: 3P4W, electronic meter, WS probes are connected right next to the
meters so WS measures exactly the same variables as the meter does. See chapter 5.1 to verify the
connection and WS screens.
Connect one voltage and one current probe to WS body (while the body is turned off). Connect also
the optical sensor. Turn on the WS. Go to the internal database and define new meter while entering
all values. Text fields are optional.
Go to Meter Error Test screen. For electronic meter calibration is not necessary. Run the test. If the
error is too far from the limit, check the optical sensor position on the meter face. Run test again or
such many times you require and save any of them to the internal memory.
You can addition perform energy tests on corresponding measuring screen.
For transformer tests check chapters within chapter 5.
