The current display on the K2 is only for the current used by the base
K2. I use it when testing the K2 for 'good health' and normal RF Gain,
but during operating I see no need to monitor it on a regular basis.
The Base K2 will indicate Hi Cur if the current draw goes above the
value set by the CAL CUR parameter, and will reduce power if that
occurs. Should you continue to get Hi Cur messages, that is an
indication of something that should be investigated.

Thanks Don,
That means that at HI PWR (>11 Watts) should disregard the displayed
PS current figures.
I thought that KPA100 processor would communicate the I Sense back to
the MCU and display the correct current figure after rescaling. I
understand that is not the case.

Ioannis,
The current display on the K2 indicates only the current for the
base K2, not for the K2 and KPA100 combination.
That is why you set the CAL CUR to 3.50 amps even though the
KPA100 will draw much more current.
Yes, the KPA100 does have a scaling on the amount of RF voltage
that is being detected. That is used for power control and has
nothing to do with the current displayed. The result of that
voltage is sent to the VRFDET signal in the K2 (Voltage of the RF
Detected).
