6.1.6 Setting Calibration Gas Concentration “SEt.C”
Operation: Hold down the [MODE] key for 2 seconds, select “SEt.C” with the [▲], [▼] keys,
and press the [ENT] key.
Set the O
2
concentration of gas used for calibration. Alternatively, this setting can be performed
while performing calibration “CAL.” The gas concentration that can be set is restricted depending on
which calibration is performed (which depends on the specification in calibration “CAL”). The oxygen
concentration of air is fixed to 20.6% O
2
, so it cannot be set. Figure 6.7 shows a setting example in 3-
point calibration “ALL.” With respect to the input method of a numerical value, decimal point, and unit,
see Section 6.6.

6.1.7 Setting Sensor Constant “SEnS”
Operation: Hold down the [MODE] key for 2 seconds, select “SEnS” with the [▲], [▼] keys,
and press the [ENT] key.
Be sure to enter the sensor constant when replacing sensors. With respect to the sensor constant,
the following five parameters are available: dZ1, dS1, dZ4, dS4, and Con4, which are on the constant
tag of the sensor. Be sure to enter the right parameter. Figure 6.8 shows a setting example. These
constants are specific to the sensor and remain the same for all operations. With respect to the input
method of a numerical value, decimal point, and unit, see Section 6.6.

Return to “SEnS.”
*The entered sensor constants are updated altogether when the input of Con4 is confirmed.
If the input is interrupted halfway, it returns to the sensor constant before the input.
