The maximum input frequency is the maximum number of INA input pulses
that the K3NP can count accurately.
The response time of the HOLD input is the time required for the K3NP to
accept HOLD input after the HOLD input turns ON. This is illustrated in the
following diagram.
Recovery time is the period required for the K3NP to become ready for the
next measuring operation after a measuring operation is completed. For tran-
sistor output Models, comparative output remains ON during recovery time.
For other models, comparative output requires more time to turn ON. When
the comparative output terminals of the output board and the HOLD input
terminals are connected, set a sufficient recovery period, considering the re-
sponse time of the HOLD input. This is illustrated in the following diagram.
