Instruction Manual
- It is mA Output Signal Test Mode.
- Press "FUNC" S/W to enter mA Output setting function.
- When "RESET" S/W is pressed, it enters Test Setting Mode.
- By pressing "UP" S/W or "DOWN" S/W, ON/OFF status can be set and when it is ON, mA out
-
function is available for use. (Default OFF)
- When a desired item is displayed, press "FUNC" S/W to set it and enter the next item.
- When "RESET" S/W is pressed, it enters Test Setting Mode.
- When Aout is OFF, it starts from 0. FND value is changed by "UP" S/W or "DOWN" S/W but mA
-
is not outputted. (Default 3mA)
- When Aout is ON, FND value outputs from 100 and output current is 20 mA. It can be changed
-
by "UP" S/W or "DOWN" S/W.
- (FND: 0~100, mA : 4mA~20mA)
- The current test mode is set to output for 1 h after the last S/W operation. After completion of
-
test, "FUNC" or "RESET" S/W must be pressed to return to Test Mode Setting Mode.
6.4.6. 485 Setting Mode
■ After setting a password, move to "UP" S/W or "DOWN" S/W then press "FUNC" S/W to enter the mode.
■ In 485 mode, when it passes 10 s after the last S/W control, it automatically returns to gas concentration display
mode.
- It is a mode that sets 485 function.
- When "FUNC" S/W is pressed, it enters Option setting mode.
- When "RESET" S/W is pressed, it returns to gas concentration display mode.
- It is channel Number Setting Function that sets Serial Number of Control Unit.
- Press "FUNC" S/W
to enter Channel number setting function.

Full Range
- Channel number is a mode that enters serial number of control unit to enable recognition of
-
operation status of each control unit at other equipment, such as PC, etc. Pressing "UP" S/W
-
or "DOWN" S/W increase or decreases Address No. Value, respectively. (Default 1)
- When a desired address no. is displayed, press "FUNC" S/W to set it and enter the next item.
- Channel No is set at "1" as factory preset and is only entered when network function is to be
-
used. When two or more control unit is used, Channel No. shall not overlap.
- Mode that sets Parity Bit, which is a format of 485 communication.
- Press "FUNC" S/W to enter Parity Bit setting function.
- When "RESET" S/W is pressed, it returns to gas concentration display mode.
- Parity Bit is an additional bit to the original data to inspect error during transmission of data.
-
Pressing "UP" S/W or "DOWN" S/W increases or decreases Parity Bit value, respectively.
-
(Default 1)
- 0 : NONE, 1: EVEN, 2 : ODD
- When a desired Parity Bit is displayed, press "FUNC" S/W to set it and enter the next item.
