From the COND menu, select whether the analogue output module is active or not. Use ON to activate or OFF to activate. From InvrS menu, you can choose which value to increase or decrease according to the sensor reading on the analogue output. This option, which is OFF by default, provides an analog output that increases or decreases in proportion to the value read at the sensor. If you turn this ON, the value read out at the sensor will increase

16

while the value at the analog output will decrease, ie an inversely proportional output will be provided.

Wave Form (VAVE.F.)

8$8(.).

The waveform of the output signal can be selected from the Vave.f menu. There are 4 options in the menu: Liner, Sin, Cos, Trian. When the liner option is confirmed with the PRG key, a linearly increasing waveform is obtained in the specified scale range. When the Cos option is confirmed with the PRG key, a waveform in the form of a waveform that starts from zero and completes a complete cosine wave is obtained at the scale interval specified. When the Sin option is confirmed, a waveform in the form of a waveform that starts at the peak value of the sine wave and completes a complete sinusoidal wave in the determined scale range is obtained. When the triangle option is selected in the same way, a triangle wave is obtained in the scale interval determined at the exact middle value corresponding to the top.

Analog Output Scale Setting (Scale)

8.2 Calibration Menu [CALIB]

8.2.1 Specify Scale Values (SCALE)

V&D/H

When your device is calibrated to its factory settings, it operates at a value range of 0-100. That is, the smallest reading on the sensor shows 0 on the screen and 100 on the screen. You can change this scale from this menu.
Use the S-LO for the minimum value of the scale, and the S-HI menus for the maximum value. To change the value, press the PRG key. After specifying the value with the UP and DOWN keys, press the PRG key again to locate the decimal point. Then press the PRG key to confirm the value.
You can use the Fctor menu to expand this scale by multiplying it by a fixed factor. The number of this factor, which is the default value of 1, is multiplied by the values of S-LO and S-HI to determine the scale value.
For example; When you set the S-LO value to 1, the S-HI value to 20 and make the factor 4, your device will run in the 4-80 value range.

OFFSET menu is designed for Loadcell applications. Zero and span points are entered manually and calibrated.
With the Catch menu, zero calibration is performed and the current value is automatically drawn to zero. After Catch is selected and confirmed with the PRG key, the value on the display is set to 0.
Value menu; It is designed to perform zero calibration manually and to reverse this value if desired. For example, if you see a value of +0,75 on the device display, you need to enter the value of -0.75 manually to perform zero calibration. After selecting the desired value with UP and DOWN buttons, confirm with PRG button.
Factor menu is used in calibration of span. For example; In loadcell application, you have a weight of 50 kg, but this value is shown as 49 kg on the device display. In this case, 50/49 is entered into the factor section and the span calibration is performed. WARNING: Changing the scale value does not change the calibration of your device, it only indicates the displayed value range on the screen. For the calibration of the instrument, 8.2.2.

8.2.2 Manual Calibration Method Determination (CALOP)

&D/2S.

Your device has been automatically calibrated during production. If you do not, you can do this calibration according to the sensor. You need to select the calibration method from this menu.

)&D/
BSQW.
VHJQW.

Factory calibration (Default) 2 point calibration Segmented calibration

In the 2-point calibration option, only the maximum and minimum points are selected. With the multiple calibration option, you can calibrate your device at up to 10 different points. For example; If the length of the sensor is 40 cm and you want to

18

calibrate at 5 different points, these points are; There must be 0 cm, 10 cm, 20 cm, 30 cm, and 40 cm points at which the sensor starts. Select the FCAL option if you want to calibrate your device to factory calibration again.

8.2.3 Number o Calibration (CL.CNT)

&/.&QW.

In this menu that appears when you select the segmented calibration option, you can specify the number of points you want to calibrate the device. It’s a maximum of 10.

8.2.4 Automatic Calibration (START)

VWD5W

From this menu, you can start your automatic calibration by pressing the PRG key according to the selected calibration method in 8.2.2. section. During the calibration that will start according to your chosen meta; You can see the calibration point to be determined on the first line by the ignored segment number and on the second line the unprocessed value read on the sensor. You can scroll through the segments, ie the calibration points, with the UP and DOWN keys. You can confirm the segment you want to specify with the PRG key while the sensor is in position for calibration. DONE will appear on the screen for a very short period of time.

8.3 Display Menu [DISP]

8.3.1 Choice of decimal point location (POINT)

SRLQW

In the value that appears on the display in run mode, you can set the position of the decimal point in this menu. This value, which is ‘2’ in the factory settings, indicates how many decimal places to display after a call. If you select ‘0’, only the whole number appears on the screen.

8.3.2 Tare Function Settings (TARE)

WDUH

In this menu you can define the Tare Function and its properties. From the EVENT menu you can select the Tare Function type: When the unit is in operation mode, each time the UP key is pressed;

]H52

ZERO: Then the value read on the sensor is equal to zero and the Tare state LED is lit.

SUVHW U.]HU2

PRESET: Then, the value read on the sensor is equalized to the specified value and the Tare status LED is lit.
REPEATED ZERO: The first time it is pressed, the value read on the sensor is equal to zero and the Tare status LED is lit. When it is pressed later, the read value returns to the state before the key is activated and the Tare status LED is turned off.

U.SUVW

REPEATED PRESET: When pressed for the first time, the value read on the sensor is equalized to the specified value and the Tare status LED is lit. When it is pressed later, the read value returns to the state before the key is activated and the Tare status LED is turned off.
19

In the PrSet option, you can specify the value to be equalized when the Tare key is pressed. If your EPA300, which is specially manufactured according to your order, has the Digital Tare Input module, you can make settings from the INPUT menu under the Tare menu. The EDGE option determines which edge of the edge signal coming from the Tare function is activated. RISE for rising edge, FALL for falling edge. For example; When you connect this signal to a button, the RISE option activates the tare when the button is pressed and the FALL option when the button is released after the button is pressed. In the FILTR option, you can specify how many milliseconds the modulated signal is to be controlled. By default, this value is 100 ms.
With the BUTTON menu, you can select whether the tare button ( ) on the front can be used. If the button is set to “Off” position, the tare button on the front side is not used, only the rear tare input can be used.

8.3.3 Screen Refresh Rate (REFRS)

UHIUV

Indicates how many milliseconds the value displayed on the screen will be refreshed. By default this value is 100 ms; To reduce or reduce the on-screen vibrations, or reduce the duration of your device’s response to movement of the sensor.

8.3.4 Blocking the on Screen Volatility (FILTR)

IL/WU

Your EPA300 is programmed to display the signals received from its connected sensor in the most accurate way on the screen by processing them with special algorithms. But; You can solve this problem by filtering from this menu in the event of a trembling of the value displayed on the screen due to various reasons such as noise in the vicinity, disturbances in the sensor. There are three different filtering methods for this:

1. AVRGE (Average Calculation): When you activate this filter by turning the STATE option ON, your device will refresh the value that appears on the display after you have read as many values from the sensor as you would select COUNT. For example; COUNT will default to 500, and your device will refresh the value on the screen after you have taken 500 samples from the sensor, that is, after reading it, taking the average of these values. Accordingly, increasing COUNT will reduce flicker on the screen; But your device will slow the response of the sensor to its rapid movement.

2. LQE(Lineer Quadratic Estimation): You can also activate this filter, also known as a thick filter, by turning the STATE option ON. If you decrease the default COVARIANCE of 500, the flicker on the screen will decrease; But your device will slow down the reaction of the sensor to its rapid movement.

20

3. HYS (Hysteresis): You can activate the hysteresis filter by turning the STATE option ON. With this filter, which has two parameters named Delta and A.Error, the value read from the sensor is not reflected on the screen until it changes to Delta. When the sum of the nonreflected values on the screen is equal to A.Error, the display is updated with the average of these values
