6.1.2 2., 3., 4. Relay Output Settings (OUT-2-3-4)
In this menu you can set the relay outputs 2, 3 and 4 of your EPA300. Complete
settings 5.1.1. The 1 st relay output described in chapter is the same as the OUT-1
settings.
6.1.3 Current and Voltage Analog Output Settings (ANLOG)
If your EPA300, which is manufactured specifically for your order, has an analog
output module, you can make the necessary settings from this menu.
Select the analogue output from the TYPE menu:
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
while the value at the analog output will decrease, ie an inversely proportional
output will be provided.
Wave Form (VAVE.F.)
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)
In the device with the analogue output feature, SCALE mode in this menu must be
ON to set the output signal to the desired scale range. S-LO started appearing on the
analogue menu afterwards. And S-HI. Options and scale values can be entered.

menu. Use ON to turn the sound on, OFF to turn it off.
6.2 Calibration Menu [CALIB]
6.2.1 Specifying Scale Values (SCALE)
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.
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, 6.2.2.
16
6.2.2 Manual Calibration Method Determination (CALOP)
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.
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
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.
6.2.3 Number of Calibration (CL.CNT)
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.
6.2.4 Automatic Calibration (START)

key according to the selected calibration method in the 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.
6.3 Display Menu [DISP]
6.3.1 Choice of decimal point location (POINT)
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.
6.3.2 Tare Functain Settings (TARE)
In this menu you can define the Tare Function and its properties.
From the EVENT menu you can select the Tare Function type:
.
.
Factory calibration (Default)
2 point calibration

.
.
.
17
When the unit is in operation mode, each time the UP key is pressed;
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.
6.3.3 Screen Refresh Rate (REFRS)
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.
ZERO: Then the value read on the sensor is equal to zero and the
Tare state LED is lit.
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.
REPEATED PRESET: When pressed for the first time, 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.
.

6.3.4 Blocking the on Screen Volatility (FILTR)
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.
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 non-
reflected values on the screen is equal to A.Error, the display is updated with the
average of these values.
6.4 Secure Menu [SECUR]
6.4.1 Hide Menu (HIDE)
You can hide the menus ON you do not want the operator to see your device to use
them.
All menus except Secure are hidden.
