50-kHz input range and 0.006% accuracy for sophisticated
control.
A wide selection of outputs: relay, transistor, BCD, linear, or
communications.
Maximum/Minimum value hold, set value write protection, and
more.
Banks with four comparative output values and four prescale
values.
Prescale function available, which displays in units of actual
physical parameters (length, volume, etc.).
Set value teaching, linear output range teaching, and prescale
teaching are available using actual measured values.
Displays values in hours, minutes, and seconds in operating
mode 6.
A startup compensation time parameter keeps the
measurement operation from sending an unnecessary output
for a preset period up to 99.9 s.

I Ratings
Note: A K3NR with DC supply voltage requires approximately 1 A DC as control power supply current the moment the K3NR is turned ON. Do not
forget to take this into consideration when using several K3NR units. When the K3NR is not in measuring operation (e.g., the K3NR has
been just turned ON or is operating for startup compensation time), the display will read "00000" and all outputs will be OFF.
