Note
•
To reset the zero point of a device with ID code “b” or later to the value at the

If a device’s ID code is not indicated, it is not possible to restore the zero point
setting at the time when the device was shipped using the loader.
Instead, use the switch on the device to restore the setting.
For details, please refer to
Micro Flow Rate Liquid Flow Meter Model F7M User’s
Manual (CP-SP-1421E).

If [Automatic setting of flow rate correction factor (CCF)] is enabled, the CCF
based on the amount of adjustment after zero point adjustment is automatically
set. If this function is used to automatically set the CCF, flow rate accuracy is not
guaranteed. For higher accuracy, use the set value as a guideline for setting the
CCF manually.
