If there is a temperature gap between the electrode and the compost, wait for 30 seconds to remove the
gap to prevent errors. Also, keep the same pressure to the sensor to stabilize the reading.
5. Press [
測定
] (“Measure”, rightmost key).
6. For accurate reading, measure the same point repeatedly and press [
平均
] (“Average”, key above + sign) to show
an average.
7. Clean the electrode after the measurement.
8. The device turns off automatically when one minute has passed.
Setting of Customized Formulae
Each angle and equilibrium of five conversion formulae can be modified individually. Formula A can also be edited,
but it is advised to remain it.
Angle change
1. Press [
選択
] (“Select”, key above − sign) to choose the formula
to be edited.
2. Press [
変更
/
決定
] (“Set”, lower left key).
A character of “A” appears at the upper right, and the current
angle is shown. The default value is “100” in all formulae.
3. Press + or − key to modify the value, available between 0 and
199. The value increases or decreases continuously by a long
press for more than 1 second.
In the right case, set it to 66 referring to the equation A*.
4. Press [
変更
/
決定
] (“Set”, lower left key) to complete, or go to
the next step if you also change the equilibrium.
Parallel change
1. Press [
測 定
] (“Measure”, rightmost key) when the angle is
displayed.
The character at the upper right changes to “H” and the current
equilibrium is shown. The default value is “0.0” in all formulae.
3. Press + or − key to modify the value, available between −19.9
and 19.9. The value increases or decreases continuously by a
long press for more than 1 second.
In the right case, set it to −3.0.
4. Press [
変更
/
決定
] (“Set”, lower left key) to complete, or press
[
測定
] (“Measure”, rightmost key) to go back to angle change.
5. If a measured value was displayed before the setting, a
recalculated value is displayed.
