Note:
A K3NC with DC supply voltage requires approximately 1 A DC as control power supply current the moment the K3NC is turned ON. Do not
forget to take this into consideration when using several K3NC units. When the K3NC is not in measuring operation (e.g., the K3NC has
been just turned ON or is operating for startup compensation time), the display will read “
00000
” and all outputs will be OFF.
