Screen Refresh Rate (REFRS)
Indicates how many milliseconds the value displayed on the screen will be refreshed. By
increasing this value, which is 100 ms by default, you can avoid or reduce the unstability on
the screen, reducing the time it takes your device's sensor to react.
7.1.4
Preventing Unstability on the Screen (FILTR)
The EPA 100 is programmed to show the signals received from the sensor connected to it in
the most accurate way by processing them with special algorithms. But; You may be able to
solve this problem with the value tremble filtering method which appears on the screen for a
variety of reasons such as noise in the vicinity, disturbances in the sensor. There are three
different filtering methods for this. As you can use these filtering methods alone, you can
use both filters together.
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; When COUNT is 500, your device will refresh the value on
the screen after you have sampled 500 times 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 screen flicker will decrease; But your
device will slow down the reaction of the sensor to its rapid movement.
3. Hysteresis Filter:
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 unprocessed value read from the sensor is
not reflected on the screen until it changes to Delta. When the sum of the unprocessed
values reflected on the screen is equal to A.Error, the display is updated with the average of
these values.
7.1.5
Second Line Identification on the Screen
When the device is in operating mode, the first line contains the value read from the sensor;
The second line is empty by default. In the second line you can type the desired parameter
or type in this menu. Parameter options; Set values of the relays (SET-1 and SET-2), Preset
value (PRSET) determined for the func- tion. You can also choose one of the fixed font
options such as various units, label number.
7.1.6
Keypad Setting (SOUND)
When you press any key on your device, you can turn the beep sound on and off from this
menu. Use ON to turn on the sound, OFF to turn it off.
