Example 1: Quick Test - Solid-state 9S meter
Meter: Solid-State, Form 9S
Voltage: 120-480V
Kh: 1.8
TA: 2.5
CL: 20
Accessory: Optical Pickup
A Quick Test consists in applying loads on the meter for at least 20 seconds (the time
can be modified) for each loads HL, PF and LL. Please note that the three potential
coils of the meter are automatically switched in parallel by the socket.
1. Connect the optical Pickup
To connect the cables:
•
Plug the RJ12 connector of the straight cable of the Optical Pickup into the
I/O port of the socket.
•
Look for the LED output pulse of the meter and position the suction cup of
the Optical Pickup over it.
Note: An optional adapter may be required on some meters and can be purchased
as an option.
2. Performing a Quick Test
Once the installation is completed and the connection to the socket and meter setup
is done (see previous section), we can proceed with the test.
Select Quick Test .
Start the sequence; the load current will increase to HL; the meter will start to send
pulses and the internal electronic standard will begin to register the energy that
passes through the meter. The test can be stop at any time.
In addition to the test parameters appearing on the display, the operator can see the
voltage and current applied to the meter, the chronometer and the cumulated
energy registered by the electronic standard.
While testing, you can check the partial results of the test scrolling up and down the
screen. You will get the results as they are done.
3. Obtaining and saving Test Results
After the three test points, the watthour measurement period ends automatically.
Then, the load is removed, and three test results are displayed: one for HL, one for
