3.13 How to use password protection
The flowmeter is protected by a password lock to prevent unauthorized personnel
from mistakenly modifying and zeroing the accumulator.
A password lock on the meter allows access to the data, but does not allow any
modification.
The password entered in the M47 window can be composed of 1-4 digits: no
password lock can be directly pressed the
key, M47 to unlock the meter,
press the key directly.
3.14 How to use the built-in data logger
The built-in data logger has 24K bytes of space and can store up to 2000 lines of
data.
Use the M50 window to open the data logger and select the items you want to
record.
Use window M51 to set the start time, recording interval and recording duration of
the recorded data. Using window M52 to select the data storage direction, the
meter can store the data in a buffer.
Data can also be transferred to the RS-232C interface without being stored in a
buffer.
Use window M53 to view the data in the buffer.
Use window M52 to clear the data from the RS-232C interface and the buffer.
3.15 How to use the frequency output function
All handheld ultrasonic flowmeter has a frequency signal output function,
networked to other devices with the frequency of the size of the instantaneous flow,
Frequency output can be set by the user, only four parameters need to be set.
In the M68 window to set the lower limit of instantaneous flow, in the M69 window
to set the upper limit of instantaneous flow.
In M67, only 4 parameters are set by the user.
The frequency range is set in window M68.
For example: a pipeline flow range is 0~3000m3/h, the corresponding frequency
signal 200~1000Hz is required to be output.
The user enters 0 in window M68,
3000 in window M69, and 200 and 1000 in window M67
