3.8 Turning the Power On/Off
• Before turning power on, verify that the instrument and
peripheral devices are correctly installed and connected.
• When using the AC adapter: AC adapter input voltage
range is 100 to 240 VAC (with ±10% stability) at 50/60 Hz. To
avoid electrical hazards and damage to the product, do not
apply voltage outside of this range.
• When the POWER LED is red or the mark is not displayed,
power is not being supplied from the mains. In this case, mea-
surements can be taken using battery power for up to about 30
minutes. Make sure the AC Adapter is securely connected to
the power outlet and to the instrument.
• Data in internal memory is erased whenever the instrument is
turned off. Therefore, to preserve recorded data, be sure to
save it to a PC Card.
