Operating the Instrument from a DC Power Source

Instruments that have the Battery option can operate from an external DC power
source (with or without batteries in the instrument). The external DC power source
must supply +11 to +18 VDC at 2.0 A (min.). It must use a 2.1 mm coaxial plug, and
its DC output plug must be wired so the inner connector is positive and the outer
connector is negative. To use an external DC power source, disconnect the AC
power cord, make sure the Battery switch on the back panel is set to 0 (off), insert
the coaxial plug into the EXT DC connector on the back panel (see
and turn the instrument on by setting the Battery switch to 1 and then pressing
the POWER button on the front panel in the normal manner.
