If a “0” is entered, there is no damping. A bigger number generally brings a more stable effect. However,
a balance is required; bigger damping numbers will slow down the instrument’s response time.

§4.10 How to set up the zero calibration
Without a zero calibration, the flow meter may give a small non-zero flow rate reading even when the
flow in the pipe is not running. In order to make an accurate measurement, it is necessary to set the
correct zero calibration. While setting this data, the liquid flow should be completely turned off. If there
is any value besides zero at the time zero velocity is set, all future results will be skewed. This window
can be accessed by pressing the following series of keys:
CAL

Zero Cal. Press the ENT key to start the zero calibration.
§4.11 How to change the flow rate scale factor
The scale factor (SF) is the ratio between the “actual flow rate” and the flow rate measured by the flow
meter. It can be determined with standard flow calibration equipment. This value can be adjusted by
pressing the following series of keys:
SET

Quick Start

Set Transducer Parameters

Scale Factor. Press the ENT key to edit the scale
factor.
§4.12 How to use the password lock
The password lock provides a means of preventing inadvertent configuration changes or totalizer resets.
When the system is locked, the user can still browse menu windows, but cannot make any modifications
to the windows.
The password locking/unlocking can be done in menu window M57, which can be accessed with the
following series of keys:
