(3) Next, change to the check target channel and check it likewise.
(4) Check also the analog indication/dot printing position.
* The accuracy of the unit is rated at an ambient temperature of 23°C ±2°C. Ensure safety of the surrounding
environment.
* When you changed the wiring with the terminal cover removed, energize the unit for at least 30 minutes
