The Model 9684 enables the instrument to be operated from a DC power source
such as a battery.
When both AC power and the Model 9684 DC Power Unit are connected to the
instrument, the AC power source has priority. However, when the instrument is
operating from AC power and the power switch of the Model 9684 is on, the
9684 is in standby state, and some power is still consumed from the DC source.
We therefore recommend turning the Model 9684 off when it is not being used.
The input voltage range of Model 9684 is 10 V DC to 16 V DC. (Voltage fluc-
tuations of ±10% from the supply voltage are taken into account.)
9684 DC Power Unit Specifications
See 15.1 General Specifications (8) Power Supply Options "9684 DC Power Unit (spec-
ify option when ordering)" (p. 399)
3.2.5 If the Model 9684 DC Power Unit is Installed
• Before connecting to a battery, confirm that the power switch on the
Power Unit is turned off. Connecting to a battery while the Power Unit is
turned on may produce sparks and could damage the instrument.
• Make sure that the Power Unit's ventilation holes are not obstructed.
Otherwise, the instrument could be damaged or a fire could result.
Whenever making DC power connections to the Power Unit, observe polarity
carefully, and make connections securely. Reversed-polarity connections may
damage the Power Unit.
