filament current output connectors. With the 11-065 power OFF and the high voltage OFF and set to zero, unplug the E92 connector and then connect a current meter that can go up to 10 amps DC between the E92 cable lug and the E92 connector on the HV1 board. Make sure that the meter leads are not touching anything.<\/p>\n\n\n\n<p><strong>CAUTION! High voltages can be present on this board.<\/strong>  As long as you have the high voltage on the 11-065 set to zero (fully CCW) and the high voltage switch set to off, then there is no high voltage present. Refer this test to someone who is trained to work safety with high voltage if you are not familiar with operating a DVM.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a
