Do not do tasks, such as moving the machine or connecting the machine with the main switch ON to
prevent electric shock.
■ Ambient Temperature: Accuracy assurance 23 +/-2 degrees centigrade
Operation assurance 5 to 40 degrees centigrade
(The average over a period of 24 hours does not exceed 35 degrees C.)
■ Relative Humidity: 45 to 60 percent, non-condensing
■ Atmosphere: Dust and corrosive gas free
■ Floor: Floor must be flat and sturdy enough for freedom from vibration during
operation.
