(3) Menu D: Total Setting items

Menu D contains parameters that are relevant to

totalization function settings.

[D10: Total Unit] Setting of units for totalization

scale

→ Refer to the description of parameter B30.

[D11: Total Scale] Setting of the totalization scale

→ Refer to the description of parameter B31.

[D12: Total Decimal Pnt] Setting of the decimal

point position for the totalization display

This parameter sets the position of the decimal

point for totalization display in terms of the number

of digits. Except in cases where 0 is selected, the

totalized units are not displayed.

Example: When totalized value is 12345678 m

Item Totalization display

0 12345678 m

1 1234567.8

2 123456.78

3 12345.678

4 1234.5678

5 123.45678

6 12.345678

7 1.2345678

[D13: Total Low Cut] Setting of the totalization stop

range

This parameter allows the settings to be made that

preventtotalizationwhentheowrateisatorbelow

the low-cut setting value. The low cut setting value

dependsonowratespan.

●Flowratespan<1m/s:

Input value or 3 cm/s, whichever is bigger

●Flowratespan≥1m/s:

Input value

Toconrmtheowratespanvelocityin”m/s”unit,

see [C44: Velocity Check].

If the multiple ranges or forward/reverse ranges is

used, low cut is carried out at the setting value for

the smallest span.

Example:Situationwhere“therstrange”issetto

“0.8 m/s” and “the second range” is set to

“1.5 m/s”

- When “5 %” is input in this parameter:

Nototalizationiscarriedoutatow

rates of 4 cm/s or lower.

- When “3 % (i.e. 2.4cm/s)” is input in this

parameter:

Nototalizationiscarriedoutatow

rates of 3 cm/s or lower.

However, the low cut function will be terminated if

this parameter is set to “0 %”.

NOTE

When the low cut is small, an incorrect output

mayoccurattheowrateofzeroandthe

totalization may be carried out. Use the

instrument with the default setting 3%. If the span

issmall,thedampingtimeisshort,ortheuidis

low conductivity, the totalization may be carried

outeasilyattheowrateofzero.Inthiscase,set

the span to be large, set the damping time to be

long, or set the low cut to be large.

[D14: Total Rate Check] Display of the totalization

rate in “Pulse/s”

This parameter displays the totalization rate, which

is converted to “Pulse/s” while 100% of the range

ows.

When the multiple ranges or forward/reverse

angesareused,theAXRdisplaysthetotalization

ratewhich100%oftheirmaximumrangeows.

[D20: Total Execution] Operation setting for the

totalization function

This parameter sets “Start” and “Stop” of the

totalization function, in addition to performing the

preset function for the forward totalized value and

the reverse totalized value.

*: The preset function starts the count for totalization from the set

value.

Item Description

Start

(initial value)

Starts totalization

Stop Stops totalization

Preset Total Sets the preset value for totalization display

hathasbeenspeciedastheforwardtotalized

value. Preset value are determined using D21:

Ttl Set Val Lower and D22: Ttl Set Val Upper.

In case that “Start” is sellected, the count for

totalization starts from the preset value. Setting

of zero as the preset value allows the zero-reset

function to be implemented.

Preset Rev

Total

Sets the preset value for totalization display

hathasbeenspeciedasthereversetotalized

value. Preset value are determined using D21:

Ttl Set Val Lower and D22: Ttl Set Val Upper.

In case that “Start” is sellected, the count for

totalization starts from the preset value. Setting

of zero as the preset value allows the zero-reset

function to be implemented.

[D21: Ttl Set Val Lower] Setting of the totalization

preset value (lower 6 digits)

This parameter sets a totalization preset value

in the lower 6 digits of the 8-digit totalized value.

If zero is to be set as the preset value, “000000”

should be set here.
