To perform current probe basic setup:
1.
Connect the current probes to the meter (in this example we are using a ION
7500 meter). Refer to the meter Installation and Basic Setup Instructions for
current probe installation instructions.
7500 meter). Refer to the meter Installation and Basic Setup Instructions for
current probe installation instructions.
2.
In a Telnet or HyperTerminal session, access the Calibration menu. Refer to the
technical note titled Telnet and HyperTerminal Access for instructions on how to
run a Telnet or HyperTerminal session.

3.
Set up the current probe transformation ratio and the phase angle.
In this example, we will set up a split core CT with AC voltage output. The
model is CT-300A-0.333V (Nominal Primary current 300A, Nominal secondary
voltage 0.333V). The phase angle is < 2.0 degrees. This is saved to register group
“User Defined 1” (1) and is the same for all phase current channels (44). Refer to
the KCTSTP command in the section “The Calibration menu contains the following
calibration commands:” on page 188.

To write these parameters to the meter, type in:
7500ION:\PORT_1>kctstp CT-300A-0.333V 300 0.333 2.0 1 44
Press Enter.

To read that the new parameters have been written to the meter, type in:
7500ION:\PORT_1>kctrd
Press Enter.

With the meter front panel or software, activate the current probe parameters set
in step 3:
in step 3:
◆
Meter front panel: select Basic Setup > Current Probe > User Defined 1.
◆
Designer software: access the Power Meter module Current Probe setup
