To power-up the DC-190 using the optional battery:

2. Turn battery switch to ON (located on the
bottom left-hand side of the scale base).
3. Press
ON/OFF and allow scale to warm up for
10 minutes. The display momentarily shows
revision number, shows all digits from 0 to 9
in a count-up mode, goes blank, shows all 8s,
and then enters normal weighing mode.
2.3.4 Battery Charging
A fully charged battery allows for approximately 4
hours of continuous use. Refer to SPEC 1 (Power Auto
Off function) for extended hours of use. It will take
approximately 8 hours to fully recharge a battery that
has been completely dissipated. The console must be
connected to the base during the recharge cycle and
the AC power cord must be plugged in.
NOTE: Do not store the scale without turning off the
battery power switch! When the battery switch is ON and
the AC is not connected, a low level battery current will flow
even if the display is OFF. To prevent battery discharge
when stored, turn the battery switch OFF whenever the unit
is not in use.

tickets. SPEC 5, bits 0 and 1 list three sequence
