6.2 CALIBRATING DEVICE
Press and hold the PRG key to switch to the programming menu.
6.2.1 Determining Scale Value
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 the 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. The display on the right will start blinking. You
can change the value using the up and down keys. Then press the PRG key again to locate
the decimal point. Then press the PRG key to confirm the value.
For a example application please see page 14.
6.2.2 Determining Factor
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 operate in the 4-80 value range.
WARNING: Changing the scale and factor value does not change the calibration of your
device, it only indicates the displayed value range on the screen. For the calibration of the
device,please see 6.2.3.


Example:
After specifying the S-LO value, you can do the same for the S-HI value.
6.2.3 Calibration Method Determination
Your device has been calibrated during production. If you want, you can do this calibration
according to the sensor. You need to select the calibration method from this menu.
6.2.3.1 Factory calibration (default)
The default calibration on your device. The multipoint calibration or the two points you
make your device does not disturb the factory calibration.

6.2.3.2 Two-point calibration
In the two-point calibration option, only the maximum and minimum points are selected. For
example; When calibrating a 10 cm linear potentiometer, the potentiometer is set to the
minimum point in the fully closed position, while the potentiometer is fully open.
6.2.3.3 Multi (segmented) calibration
With the multiple calibration option, you can calibrate your device at up to 10 different
points. This method increases the linearity of the sensor.
For example; If the length of the sensor is 40 cm and you want to calibrate at 5 different
points, these points are; There may be 0. cm, 10. cm, 20 cm, 30 cm, and 40 cm points where
the sensor ends. These points can be set anywhere in the scale range. We recommend that
you choose equal intervals for a more suitable linearity.
6.2.3.3.1 Number of Calibration (CL.CNT)
In this menu, which 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
From this menu, you can start automatic calibration by pressing the PRG key according to
the calibration method you selected in section 6.2.3.
∙If you have set the calibration method to Two Point Calibration, press the PRG key and
CAL-L will blink while the sensor is at the minimum point. Press the PRG key to set the CAL-L
value. After this, the CAL-HI indicator will blink while you move your sensor to the maximum
point. Press the PRG key to set the CAL-HI value.
∙If you have set the calibration method to Multi Calibration. During calibration; You can see
the calibration point you will set on the first line with the flashing segment number and on
the second line the unprocessed value read on the sensor. You can select the segment with
the up and down arrow 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.
Note: During calibration the unprocessed value read from the sensor appears on the second
line of the display. Do not confuse this value with a scale value.
6.2.5 Error Message
This error message can only be seen on devices with
4-20mA and 0.5-4.5V inputs. Meaning; The sensor is not
connected to the device or the sensor is defective.

6.3 ENTER RELAY SET VALUE
Your device has two relays in total with two contacts, normally open and normally closed.
You can use the relay contacts in five different functions depending on your need. These
functions are described in 6.4.1
6.3.1 Relay 1 Output Settings (OUT-1)
Note: You can also set relay 2 output setting in the same way.
6.3.2 Changing Quick Set Values
Press and hold the ESC key to quickly change all adjustable setpoints while the device is in
run mode. You can then change the desired SET value by pressing the PRG key. When
entering a value, press and hold the UP and DOWN keys to move to the next step. To enter a
negative (-) value, press the DOWN key to come to one of the non-digitized steps.

6.4 TRANSITION TO PROGRAMMING MODE
6.4.1 Selection of Relay Function
This function selection determines when the relay output will switch on and switch off
according to the set values.
 .
When the value read in the device reaches or exceeds
Set-1, the relay switches off.
When the value read in the device is between Set-1A and
Set-1B value, relay switches off
The value read on the device remains set to the value of
Set-1 by increasing or decreasing the value of the relay
each time it switches off.
The value read in the device remains set to the value set by the
set-1A or set-1B value each time the relay is switched off.
The relay remains switch off until the value entered when
the value read in the device passes the Set-1 value or the
value of Set-1 at every level such as 2,3,4,5
The relay does not switch off in any way.

6.4.2 Delay
The relay specifies in seconds how long it will active and inactive after it is switched off. If '0'
is entered as a zero value in the Stand function, the relay will remain switch on unless the
relay output condition changes.
6.4.3 Histerezis
Due to the unstability in decimal value read on the connected sensor, you can enter the
hysteresis value to prevent the relay from being turned on and off at any time, so that the
set value you set for the relay will be activated and inactivated as low as Hysdn and above
Hysup.
6.4.4 Offset Value
If you want to add offset to the entered set value, this menu is used. If all set values are
selected forward or negative by the specified offset value, they are shifted back.
6.4.5 The Default State of The Relay
Depending on the factory settings of your device, the relay is normally off, so you can change
it normally. Use the Cond option for this. The factory setting NC (Normally Closed) means
that the relay is normally closed, NO. (Normally Open) indicates that the relay is normally
open.
6.5 ANALOG OUTPUT SETTINGS
If your EPA 100, which is specially manufactured according to your order, has analog output
module, you can make the necessary settings from this menu.
6.5.1 Analog Output Type Selection
6.5.2 Analogue Output On Off
Use ON to activate the analog output, OFF to turn it off.
6.5.3 Inverse
You can choose which value to increase or decrease according to the sensor reading on the
analog 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
