Power requirements
The AutoSigma 3000 can only be operated by battery,
using three AA size cells, Alkaline (preferred), Dry
Cell, or Ni-Cad .
H
Note:
If Ni-Cad batteries are used the battery level indica-
tion will not be correct, and they should be removed
for charging when the level indicator shows about
25 %. The AutoSigma 3000 has no provision for in situ
charging.
– Undo Battery Cover Screws and lift off the cover
(the screws are captive in the lid).
– Insert three AA alkaline cells as shown.
Alternative cells may be used if alkaline batteries are
not available, but unit operating time may be reduced
and battery level indication inaccurate.

If the batteries are installed incorrectly with the polarity
reversed, no damage to the AutoSigma 3000 will oc-
cur, but the instrument will not function.
– After the batteries have been installed, replace the
battery cover and refi t the screws. The Icon on the
display shows the battery charge.
