4. OPERATION MODE
The instrument has three displays, and each one has three LED indicators (red,
green and yellow). Every LED indicates the parameter presently shown by display.
When you switch on the power supply of the CVMk, all the 9 LED indicators will light
on for some seconds, and you will see on the display : "Circutor xxxx" (program
version) and following you will read "CARD TYPE xxxx" (identification of the
connected module). After some seconds the instrument is ready to work, showing
one of the three possible screens. One of the leds next to each display lights on
indicating the parameter being measured.
display
When the first LED (red) of every display is lighting on, it means that we are reading
VOLTAGE values. That is, the first display shows the voltage of phase L1 (V1), the
second one the voltage of phase L2 (V2) and third one the voltage of phase L3 (V3).
If you press the "display" key, the three red LEDs will light off, and the three green
LED will light on. It means that we are now reading the CURRENT values for each
phase (A1, A2, A3). However, this screen can be configured in order to display other
different parameters.
When pressing again the "display" key, the three yellow LEDs will light on and we
will see on display the three previously programmed parameters (see point 5.5. in the
SETUP section).
If you press the "display" key again you repeat the above mentioned process.
