Turning the Instrument On and Off

WARNING

Before turning on the instrument, verify that the supply voltage you plan to use falls within the supply voltage range noted on the instrument’s AC Adapter.

Supplying a voltage that falls outside the specified range to the AC Adapter could damage the instrument or AC Adapter, causing bodily injury.

 CAUTION

Do not input a voltage to input terminals while the instrument or wireless module is off.

Doing so could damage the instrument or wireless module.

IMPORTANT

  • Be sure to turn off the instrument and any wireless modules after use.

  • The instrument and wireless modules will not malfunction in the event of a momentary power interruption lasting 40 ms or less. However, an interruption lasting longer than 40 ms will cause the instrument and wireless modules to malfunction. Check the condition of the power supply being used. In addition, you can continue measurement even in the event of an outage by using the Z1007 Battery Pack.
