Current Probe Inputs Basic Setup Technical Note
Telnet and HyperTerminal Access
To perform current probe basic setup, you need to access the meter Calibration 
menu in a Telnet or HyperTerminal session:
Telnet: select Debug Parser > KAL? (Display Calibration Help Screen).
HyperTerminal: select the KAL? (Display Calibration Help Screen).
Refer to the technical note titled Telnet and HyperTerminal Access for instructions on 
how to run a Telnet or HyperTerminal session.
To learn more about the Calibration menu, help, and commands refer to the 
section “Calibration Menu and the KCTSTP/KCTRD Commands” on page 188.
Current Probe Basic Setup
Basic setup for current probes involves programming the meter with the current 
probe transformation ratio, and if necessary, the phase angle provided by the 
current probe manufacturer (phase angle correction is necessary if energy readings 
accuracy is required). These parameters are saved to the meter as User Defined 1 or 
User Defined 2 and are activated on the meter with the meter front panel or 
software. 
In the following example, we will set up a ION 7500 meter to match current probes 
that have a 300A primary rating, a 0.333V output, and a phase shift of 2
° 
(as 
specified by the current probe manufacturer)
In a Telnet or HyperTerminal session, we will set up the parameters using the 
KCTSTP write command, and save this to the meter as User Defined 1. (Refer to the 
KCTSTP command in the ”The Calibration menu contains the following calibration 
commands:” section)
.
Next, we will verify our setup with the KCTRD read command. Finally, with the 
meter front panel or software, we will access the Power Meter module Current 
Probe
 setup register, and select User Defined 1. This activates the meter with the 
parameters we have set in this example.
C
AUTION
Before changing meter parameters, use the Calibration menu KCTRD read command to display the
meter default settings. Print out the default settings, and store the printout so you can refer to the default
settings later if required.
