The response time of the HOLD input is the time required for the K3NP to
accept HOLD input after the HOLD input turns ON.
Recovery time is the period required for the K3NP to become ready for the
next measuring operation after a measuring operation is completed. For
Transistor 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 response time of the HOLD input. This is illustrated in the following dia-
gram.
