very long. The charger can be connected to the handset all the time when an
around-the-clock measurement is required.
when fully recharged, the terminal voltage reaches around 4.25V. The terminal
voltage is displayed on window M07. when the battery is nearly consumed, the
battery voltage drops to below 3V. The user can obtain an approximate battery
working time from the battery voltage.
A software battery working time estimator is integrated in this instrument based on
the terminal voltage. Please note that the estimator may have relatively bigger
errors in the estimated working time, especially when the voltage is in the range of
around 3.70 to -3.90 volt.
2.2 Power On
Press the key to switch on the instrument and press the to turn off the
power.
Once the flow meter is switched on, it will run a self diagnostic program, checking
first the hardware and then the software integrity. If there is any abnormality,
corresponding error messages will display.
Generally, there should be no display of error messages, and the flow meter will go
to the most commonly used Menu window Number 0l (short for M01) to display the
Velocity, Flow Rate, Positive Totalizer, signal strength and signal Quality, based on
the pipe parameters configured last time by the user or by the initial program.
The flow measurement program always operates in the background of the user
interface. This means the flow measurement will keep on running regardless of any
user menu window browsing or viewing. Only when the user enters new pipe
parameters will the flow meter change measurement to the new parameter
changes.
when new pipe parameters have been entered or when the power has been just
switched on, the flow meter will enter an adjusting mode to make the signals
magnified with proper amplification. By this step, the flow meter is going to find the
best threshold of receiving signal. The user will see the progress by the number 1,
2, or 3, which are indicated on the right lower corner of the LCD display
