Performing Auto Sensor Calibration and Zero Adjustment
1. On the sensor calibration screen, press 2(CALIB).
• A screen like the one shown below will appear after the first sampling operation starts.
First sampling operation
Real-time display of sampled values
2. After the sampled value stabilizes, hold down w for a few seconds.
• This registers the first sampled valued and displays it on the screen. At this time, the
cursor will appear at the bottom of the display, indicating that a reference value can be
input.
3. Input a reference value for the first sample value and then press w.
• A screen like the one shown below will appear after the second sampling operation starts
automatically.
Second sampling operation
4. After the sampled value stabilizes, hold down w for a few seconds.
• This registers second sampled valued and displays it on the screen. At this time, the
cursor will appear at the bottom of the display, indicating that a reference value can be
input.
5. Input a reference value for the second sample value and then press w.
• This returns to the sensor calibration screen.
• E-CON4 calculates slope and
y-intercept values based on the two input reference values
and automatically configures settings. Automatically calculated values are displayed on
the sensor calibration screen.
k Performing Sensor Zero Adjustment
1. On the sensor calibration screen, press 3(ZERO).
• A screen like the one shown below will appear after sampling starts.
