6.4.2. PROGRAM MODE
- Decimal point is used when it is necessary to change decimal point for measured range.
-
Decimal point position is set by pressing "UP" S/W or"DOWN" S/W where it changes as shown
-
on the left. (Default 100)
-
Ex)100, 10.0, 1.00
-
When a desired decimal position is displayed, press "FUNC" S/W to set it and enter the next item.
- When "RETURN" S/W is pressed, it returns to Program Mode.
- It is High scale setting mode, which sets the max. gas concentration to be displayed.
- High scale value is set in accordance to the domestic regulations as factory setting.
- When "FUNC" S/W is pressed, it enters high scale setting mode.
- When "RESET" S/W is pressed, it returns to Program Mode.
- High scale changes a set value according to measuring range. Scale value increases or
-
decreases upon pressing "UP" S/W or "DOWN" S/W, respectively. (Default 100)
- When a desired high scale is displayed, press "FUNC" S/W to set it and enter the next item.
- When "RESET" S/W is pressed, it returns to Program Mode.
- This setting mode is configured with the same measuring range as gas detector when
-
delivered. Ex.) When range is set to 100.
-
For 4 mA/DC output ... 0 Display
For 20 mA/DC output ... 100 Display
- SAD setting mode to correct measurement error occurring from the detector.
- When "FUNC" S/W is pressed, it enters SAD setting mode.
- When "RESET" S/W is pressed, it returns to Program Mode.

■ After setting a password, move to "UP" S/W or "DOWN" S/W then press "FUNC" S/W to enter the mode.
■ In Program setting function, when it passes 10 s after the last S/W control, it automatically returns to gas
concentration display mode.
- When "FUNC" S/W is pressed, it enters Program Mode.
- When "RESET" S/W is pressed, it returns to gas concentration display mode.
- It is gas selection function that can be selected by gas type.
- When "FUNC" S/W is pressed, it enters Gas Selection Mode.
- When "RESET" S/W is pressed, it returns to Program Mode.
- For each TY selection, High-Scale, d-PS, Alarm (1, 2, 3), Alarm direction, Stand-by mode
-
output, Sensor output characteristic direction, Temperature compensation functions change
-
accordingly.
- Decimal point position is set by pressing "UP" S/W or"DOWN" S/W where it changes as shown
-
on the left. (Default TY1)
- Value that changes upon TY1 selection (Ex. Tx)
- Decimal position setting -> Default 0, Max. gas concentration display possible -> Default 100
- Alarm threshold 1 -> 20 H, 2 -> 40 H, 3 -> 50 H
- Stand-by output -> Default 0, Sensor output characteristic direction -> Default dec
- Value that changes upon TY2 selection (Membrapor O2)
- Decimal position setting -> 1 (25.0) Max. gas concentration display possible -> 250
- Alarm threshold 1 -> 18.0 L, 2 -> 15.0 L, 3 -> 23.0 H
- Stand-by output -> Default 20.9, Sensor output characteristic direction -> Default inc
- Temperature compensation function -> Default ON
- TY3 and TY4 are back up and not used currently.
- When a desired TY is displayed, press "FUNC" S/W to set TY and enter the next item.
- When "RESET" S/W is pressed, it returns to Program Mode.
- It is decimal position setting mode, which is the first function in program data setting mode.
- When "FUNC" S/W is pressed, it enters decimal setting mode.
- When "RESET" S/W is pressed, it returns to Program Mode.
