Common Return for all outputs
*1
When the Drift Compensation is enabled, receiving this signal resets the current Drift compensation value.
When the Mastering Compensation is enabled, receiving this signal starts the Mastering value sampling process
and resets the previous Mastering value.
*2
Input the necessary BCD codes.
*3
This signal is transmitted when the test time is extended due to NR (Noise Reduction) or Mastering value sampling.
Use the signal to disable the cycle timer over alarm if necessary.
Power Source
Operational power supply is required to use the Control I/O port.
Rated input voltage: 12 - 24 VDC ±10%, 0.2 A MAX.
Never short the pins
