forget to take this into consideration when using several K3NP units. When the K3NP is not in measuring operation (e.g., the K3NP has been just turned ON or is operating for startup compensation time), the display will read “00000” and all outputs will be OFF.

Transistor Inputs: ON: Residual voltage must be 3 V max. OFF: Leakage current must be 1.5 mA max. The switching capacity must be 20 mA or greater.

When the external signal input is short-circuited, a voltage of approximately 5 V will be applied to between the terminals 5 to 7 and the COM terminal, and a current of approximately 18 mA (nominal value) will flow.
