To check the present HV current value (JTU-35, JTU-17 only)
The HV (High Voltage) current of the JumboTron display unit is measured
and displayed in the display window.
In step 2 on page 34, set "SCREEN No. (JTU-17 only) and "UNIT
Address," then select "Ip" to display the data.
The unit measures the HV current, and the measured value is displayed in
the display window.
To check for defective cells (JTU-35, JTU-17 only)
The JumboTron display unit checks for defective cell and shows it in the
display window.
In step 2 on page 34, set "SCREEN No." (JTU-17 only) and "UNIT
