Section 2. Connecting with the analyzer
Powering the LI-830 and LI-850
A power supply—either a battery or the universal power adapter—can be connected
to the LI-830 and LI-850 power jack or to pins 1 and 2 on the terminal strip. The
instruments require 12 to 30 VDC. The power supply must be able to provide 14
watts (1.2 A at 12 V) during warmup and about 3.6 watts (0.3 A at 12 V) during nor-
mal operation.
Using the universal power adapter
The included power supply is compatible with mains power in most localities glob-
ally (input 100 to 240 VAC, 50 to 60 Hz; output 12 VDC, 2.5 amps). You may need
to install different blades from the outlet adapter kit to fit your wall outlets.
