4.6.2

Set zero flow

On some applications and in some conditions it may be that
although there is no flow the instrument may show a small offset
due to picking up noise. This is an offset that can be cancelled out
and will increase the accuracy of the instrument. By selecting this
option and pressing ENTER the display will show the following.

SET ZERO FLOW yy-mm-dd hh:mm:ss

Stop the flow COMPLETELY and then

press ENTER

Press SCROLL to cancel

Pressing ENTER before the flow has stopped will result in an error message which asks are you sure the flow has stopped.
This occurs when the flow is still above 0.25m/sec. When this option has already been selected, press ENTER to cancel the
previous instruction, then it is possible to re-set the Zero balance. This option is not available when error messages E1 and E2
(See 5.2) are being displayed.

4.6.3

Total

This option allows the user to disable both the positive and negative totalisers. As soon as either of these options are selected the
totaliser will start or stop functioning. It does not zero the total, this is a separate function described below.
4.6.4

Reset + total/total

The UFM 610 P has forward and reverse totalisers, which can be reset when this option is selected. Use the scroll keys to select
then press ENTER to reset. The Total is stored when unit is switched off or battery goes flat, therefore may need to be reset
before each use.

4.6.5

Damping (Sec)

This option is used when the flow readings are unstable due to turbulence caused by obstructions or bends etc. Damping or
averaging can be used to make the readings more stable. It can be set to up-date the display, anything between 3 and 100
seconds.

4.6.6

Calibration factor

This facility should not need to be used in general use. One reason could be that a guide rail was being used that had not been
calibrated with the instrument and had been supplied as a spare. This could cause the instrument to be out of calibration.

If for any reason the instrument goes out of calibration and the readings may be higher or lower than normal then this facility
enables the user to correct the reading.

If for example the reading is 4% higher than normal then entering 0.96 will reduce the reading by 4%. If the reading was 4%
lower than normal then entering 1.04 would increase the reading by 4%. When the instrument is supplied it will always default
to 1.00 and when this is changed it will stay in the memory to whatever it has been changed to, until such time as it needs to be
changed again.
