If “RESET” S/W is pressed, the mode is returned to the gas concentration display
mode.
This is the mode to set entering current of 20mA
If ”FUNC” S/W is pressed, the mode is changed to the mode displaying the current
value entered in number
If “RESET” S/W is pressed, the mode is returned to the gas concentration display
mode.
▼
OR
This is the mode displaying the value converted in the processor by entering the
current of 20mA to (mA) terminal.
If “FUNC” S/W is pressed when the number is displayed stably, SUS (Success) is
displayed when the current within normal range is supplied and the screen is
changed for next item.
If the current other than normal range is entered, C-F (Calibration-Fail) is displayed
and the current value entered is displayed. Verify the current entered and check
again by pressing “FUNC” S/W.
▼▲
This is the mode after selecting “oUt” and followed the input current mode and to
set the output current of 4mA.
(Default 4.00)
Connect the ampere meter to the 4~20mA output terminal and if press “FUNC”
S/W when the value of ampere meter and the value displayed in FND are same,
the output current is set and the screen is changed for next item
If “RESET” S/W is pressed, the mode is returned to the gas concentration display
mode.
▼ ▲
This is the mode to set the 20mA output current.
(Default 20.00)
Due to display limit of FND, the tens digit and decimal values are displayed in 0.5
seconds unit.
Connect the ampere meter to the 4~20mA output terminal and if press “FUNC”
S/W when the value of ampere meter and the value displayed in FND are same,
the output current is set and the screen is changed for next item
If “RESET” S/W is pressed, the mode is returned to the gas concentration display
mode.
▼ ▲
This is the mode to test the output current after completing the calibration.
(Default 4.0)
The output current from 3.0mA to 21.0mA can be checked using “UP” S/W and
“DOWN” S/W.
If “ “FUNC” S/W is pressed after completing the check, the screen is changed for
next item
If “RESET” S/W is pressed, the mode is returned to the gas concentration display
mode.
The message notifying that the setting functions are finished is displayed with
“END” for 2 seconds and the mode is returned to gas concentration display mode
