How to Use
3.1 How to determine if the instrument is working properly?
When ‘R’ is displayed in the lowest right corner of LCD display, the instrument is working properly,
generally speaking.
If an ‘H’ flashes on than place, there could be poor signal received. Please refer to the chapters on
diagnosis.
If an ‘I’ is displayed, it means that there is no signal detected.
If a ‘J’ is displayed, it means that the hardware of this instrument could be out of order. Refer to the chapter
on diagnosis.
3.2 How to judge the liquid flowing direction?
(1)
Make sure that the instrument works properly
(2)
Check the flow rate for the indication. If the displayed value is POSITIVE, the direction of the flow will
be from the RED transducers to the BLUE transducers; if the displayed value is NEGATIVE, the direction
will be from the BLUE transducers to the RED transducers;
3.3 How to change between units systems?
Use menu window M30 for the selection of unit system in English or Metric system.
3.4 How to select a required flow rate unit?
Use menu window M31 to select the flow unit first and then the base time unit.
3.5 How to use the totalizer multiplier?
Use window M33 to select a proper totalizer. Make sure that the totalizer pulse rate is appropriate for the
application, the receiving instrument yet still output the resolution necessary to properly characterize the
flow.
If the totalizer multiplier is too small, there can be a loss of accumulation pulse because the output device
can output only one pulse in a measurement period (500milliseconds)
If the totalizer multiplier is too large, the output pulse will be too fewer for the devices that are connected
with the instrument for a quicker response.
3.6 How to open or shut the totalizers?
Use M34, M35 and M36 to turn on or turn off the POS, NEG, or NET totalizer respectively.
3.7 How to reset the totalizers?
Use M37 to reset each respective totalizer.
3.8 How to restore factory default setting?
Use M37, when the ‘selection’ message is displayed. Press the dot key first and the message ‘Master
Erase’ will display, then press the backspace key.
The master erase step will erase all the
parameters entered by the user and setup the instrument with default values.
3.9 How to use the damper?
The damper acts as a filter for a stable reading. If ‘0’ is entered in window M40 that means there is no
damping. A larger number slows down the instrument’s response causing it to appear more stable.
However remember that a larger setting will prevent a quick response in a dynamic situation..
Numbers 0 to 10 are commonly used for the damper value.
