It is the function using "FUNC" S/W, the cases for consecutive pushing of S/W occur.
-
When "FUNC" S/W is operated upon Yes/no to prevent this, "1" -> "11" -> "111" -> "1111" is
-
outputted in FND from the left side by the unit of 0.5s .
-
Upon selection of "YES" , initialization is completed, and the display state of gas concentration is
-
returned to.
-
Upon selection of "no" , the display state of gas concentration is returned to without initialization.
-
Upon selection of "RESET" S/W, the display state of gas concentration is returned to without
-
outputting in FND.

6.5.9. Initialization function for calibration data(Calibration Initial)
■ When the power supply is turned ON with "FUNC" S/W + "DOWN" S/W pushed, it can be entered into.
■ Calibration Initial is the function for initialization only of calibration value among product's setting values to the
basic setting value upon factory shipment.
-
Mode where only calibration data among the currently saved data to the existing data upon
-
factory shipment.
-
When "RESET" S/W is pushed, the display state of gas concentration is returned to.
- Enter by pushing "FUNC" S/W.
- Yes/no states can be set by using "UP" S/W or "DOWN" S/W. In the case of Yes, Calibration
-
Initial function can be used. (Initial value no)
- When "RESET" S/W is pushed, the display state of gas concentration is returned to.
- It is the function using "FUNC" S/W, the cases for consecutive pushing of S/W occur.
