８. BASIC OPERATIONS FOR SETTING DISPLAYS
Basic operations for setting displays are shown as below.
The following is an example for changing the voltage of sensor power supply.
①By pushing the “MENU” key in the measurement mode, the display moves to the setting display and displays the 1st layer (major
categories).
By moving the cursor with “arrow key (UP/DOWN)”, the selection of major categories to set can be changed.
*On the 1st layer, by pushing the “MENU” key, the display returns to the measurement display.
②Pointing the cursor to a major category to set and pushing “arrow key (RIGHT)”, the display moves to the 2nd layer (small categories)
By moving the cursor with “arrow key (UP/DOWN)”, the selection of small categories of the setting can be changed.
If the “arrow key (LEFT)”is pushed, the display returns to the 1st layer.
*On the 2nd layer, by pushing the “MENU” key, the display returns to the measurement display.
③Pointing the cursor to a small category to set and pushing “arrow key (RIGHT)”, the display moves to the 3rd layer (setting items).
If the “arrow key (LEFT)”is pushed, the display returns to the 2nd layer.
*On the 3rd layer, by pushing the “MENU” key, the display returns to the measurement display.
④By moving the cursor with “arrow key (UP/DOWN)”, select a setting item.
If the “arrow key (LEFT)” is pushed, the display returns to the 2nd layer.
⑤At the selected setting item, by pushing “arrow key (RIGHT)”, the display moves to the 4th layer (setting contents) and a current
selected content has a check mark. If the “arrow key (LEFT)” is pushed, the display returns to the 3rd layer.
⑥By moving the cursor with “arrow key (UP/DOWN)”, select a content.
If the “arrow key (LEFT)” is pushed, the display returns to the 3rd layer.
⑦By pushing the “ENTER” key”, the selected content is confirmed and a check mark accompanies.
If the “arrow key (LEFT)” is pushed, the display returns to the 3rd layer.
⑧By pushing the “MENU” key, the selected content is stored and returns the measurement display.
*If the power is shut down before being pushed the “MENU” key, the selected content is not stored.

９. SETTING EXAMPLES
The instantaneous followings are some examples for some
necessary setting point and operation methods to perform flow
measurements.
９－１. SETTING EXAMPLE 1
Detecting pulses from a gear wheel which generates 5 pulses
per 1 round by proximity switch (open collector output) and
displays the revolving speed in [rpm].
①Input type setting
The sensor is an open collector type, therefore “open
collector” should be selected as the input type.
②Setting for revolving speed display
For setting of Instantaneous display coefficient, Number of
rotation per 1 pulse is needed.
・Calculate the number of rotation per 1 pulse.
Because of 5 [Pulse] per 1 round, therefore,
1/5＝2×10-1[round]
・Set ” 2.00000×10-1” as the Instantaneous display
coefficient
・Unit to display is [rpm],therefore, select “Min” for the
instantaneous unit time.
・By “instantaneous decimal point position”, set the number
of digits after the decimal point.
③Setup steps
Although setup steps are basically same as “8.BASIC
OPERATION OF SETTING DISPLAY”, setting of
instantaneous display factor is needed, an example is
shown below.
９－２. Setting Example 2
Using a gearbox of 805[rpm] with an open collector output,
displaying the circumferential speed of the roll diameter
350[mm] in [m/min]
（conditions）
・rotation speed 805[rpm] （output pulse 60[P/R] built-in）
・reduction ratio 1/90
・roll diameter 350[mm]
①Input type setting
The sensor is an open collector type, therefore “open
collector” should be selected as the input type.
②Setting for circumferential speed display
For setting of Instantaneous display coefficient, travel distance of
rotation per 1 pulse is needed.
・calculation of circumferential speed
805[rpm] ×1/90× (0.35[m]×3.14)=9.82994[m/min]
・Cumulate travel distance per 1 pulse
1/60[P/R]×1/90×（0.35[m]×3.14）＝2.03518×10-4[m/Pulse]
・Set “2.03518×10-4” as the Instantaneous display coefficient
・Display is in [min],therefore, “Min” is selected for the
instantaneous unit time.
・By “instantaneous decimal point position”, set the number
of digits after the decimal point.
９－３. SETTING EXAMPLE 3
When maximum flow rate is approx. 40[ℓ/min], using a sensor of
rating 7.5[mℓ/Pulse] (open collector type), instantaneous flow
rate will be displayed in [ℓ/min].
①Input type setting
The sensor is an open collector output type, therefore select
“open collector” as input type.
②Setting for instantaneous flow rate display
Set flowrate per 1 pulse as instantaneous display
coefficient
Although instantaneous flow rate will be displayed in
[ℓ/min], the rating of the sensor is 7.5[mℓ/Pulse], it should
be converted to 7.5×10-3[ℓ/Pulse].
・Set the “Instantaneous display factor” as “7.50000×10-3”
・Displayed unit is [ℓ/min], therefore select “Minute” as the
instantaneous unit time.
By “instantaneous decimal point position”, set the number
of digits after the decimal point
９－４. SETTING EXAMPLE 4
Using a sensor (Voltage output type) which outputs 15 [Hz] for
90[ℓ/min], instantaneous flow rate will be displayed in [ℓ/sec].
①Input type setting
The sensor is Voltage output type, therefore select “LOGIC”
for “input type”.
②Setting for instantaneous flow rate display
Set flowrate per 1 pulse as “instantaneous display
coefficient”.
・Calculate number of pulses per 1 [ℓ].
The sensor outputs pulses of 15[Hz] at 90[ℓ/min], therefore,
（15×60）/90＝10[Pulse/ℓ] .
・Calculate flowrate per 1 pulse.
Number of pulses per 1 litter is 10[Pulse/ℓ], therefore,
1/10＝1×10-1[ℓ/Pulse].
・Set “1.00000×10-1” for the “instantaneous value display
coefficient”.
* Any settings of “1.00000×10-1”, “0.10000×100” and
“0.01000×101”for the “instantaneous value display
coefficient” bring same results.
・Unit to display is [ℓ/sec], therefore, select “Sec” for the
“instantaneous unit time”.
・By “instantaneous decimal point position”, set the number
of digits after the decimal point.
１０. SETTING OF UNITS
Units are selectable and can be displayed optionally.

AL1, instantaneous measured value of Bch is assigned to AL2
and instantaneous calculate value is assigned to AL3,4 and so on.
Every display item can be freely assigned to comparative
outputs.
Setting procedure is same as “8. BASIC OPERATIONS FOR
SETTING DISPLAYS”. Operate in the track of the procedure of
SETTING DISPLAYS.
Caution: COM (emitter) terminal is common for AL1-AL4 in
open-collector output products. Each AL1&2, AL3&4 have
common terminal in relay ouput products.
１１－３. COMPARISON JUDGEMENT VALUE

judgement results and their outputs OFF.
１２－３. MEASUREMENT INHIBIT FUNCTION
The measurement inhibit function ignores the input and the
display value accompanies this.
Measurement inhibit A：inhibits the input of Ach
Measurement inhibit B：inhibits the input of Bch
Measurement inhibit A&B：inhibits the inputs of both Ach
and Bch
１２－４. DISPLAY HOLD FUNCTION
Display hold function holds display value. While this function is
valid, measurement action is performed internally and the latest
measurement value is displayed when the function become
invalid.
Display hold A：holds the display of Ach
Display hold B：holds the display of Bch
Display hold A&B：holds the display of Ach and Bch
１２－５. MAXIMUM VALUE HOLD FUNCTION
Maximum value hold function is the function which holds the
maximum display value.
Maximum hold A：holds the maximum display value of Ach
Maximum hold B：holds the maximum display value of Bch
Maximum hold A&B：holds the maximum display value of
Ach and Bch
１２－６. MINIMUM VALUE HOLD FUNCTION
Minimum value hold function is the function which holds the
minimum display value.
*When both of the maximum value hold and the minimum value
hold are ON simultaneously, only the maximum value hold
becomes valid.
Minimum hold A：holds the minimum display value of Ach
Minimum hold B：holds the minimum display value of Bch
Minimum hold A&B：holds the minimum display value of Ach
and Bch
