6.Disconnect black (–) and red (+) electrical leads from battery (see Figure 2-8). Remove existing DC battery pack. Attach red lead to positive (+) side of battery.

7.Attach black lead to negative (–) side of battery.

8.Place new DC battery pack in battery compartment.

If the DC-190 scale is operated with the Caution battery pack removed, isolate the

positive (+) and negative (–) leads so that they do not make contact with each other or any part of the scale frame or any sensitive electronic components.

2.3.3DC Battery Operation

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

1.Remove AC power cord from bottom of scale.

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.

2.3.4Battery 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.
