Vibration resistance Functional 10 to 55 Hz (1 cycle/min.), single amplitude: 0.15 mm (10 min. on 3 axes)
Destructive 10 to 55 Hz (1 cycle/min.), single amplitude: 0.375 mm (1 hr. on 3 axes)
Shock resistance Functional Min. 98 m/s2 (4 times on 3 axes)
Destructive Min. 294 m/s2 (5 times on 3 axes)
Operation temperature --10 to +55°C/ +14 to +131°F (without frost or dew)
Storage temperature --25 to +65°C/ --13 to +149°F (without frost or dew)
Ambient humidity 35 to 85% RH (non-condensing)

Explanation of Operation

1.Time measuring takes place when the start input is ON.

2.When the elapsed (measured) time reaches full scale it returns to "0", and then measuring starts again from "0".

3.When reset input is ON, the display becomes "0". You cannot measure during reset input.

For PC board mounting type the display disappears while the reset input is ON; however, the display reads "0" when the reset input turns OFF.

4.Press the front reset button if you want to perform a manual reset (for panel installation type)
