2.2 Selecting the Location
This equipment should be used in an environment free from vibration, temperature extremes or highly corrosive conditions.
These factors may affect normal operation of the unit.
Scale bases used with the CKW-55 Indicator must be located on a stable level surface and kept away from vibrating sources
such as large machinery or appliances.
Adjust the leveling feet so that the bubble is centered in the
circle of the level indicator located in the rear of the scale.
Note: Ensure that the scale is level each time its location is changed.
2.3 Connecting Power
2.3.1 AC Power
Plug the AC power cord into a properly grounded power outlet. The CKW Indicator utilizes a universal switching power
supply that operates from 100 to 240 VAC / 50 to 60 Hz.
2.3.2 Battery Power (Optional equipment)
The scale can be operated on the internal rechargeable battery when AC power is not available. The scale will automatically
switch to battery operation if there is a power failure or the power cord is removed. A fully charged battery can operate the
scale for over 10 hours independent of the AC power line. When the battery requires charging, Lo Bat is displayed during
operation. The scale will automatically turn off when the battery is fully discharged.
With AC power applied to the scale, the bar graph may start flashing a yellow bar segment indicating charging is in
progress. As the battery is charged, the segments on the bar graph continue to advance until the first green segment is
reached. A flashing green segment indicates that the battery is fully charged.
Before using the scale on battery power for the first time, the internal rechargeable battery requires charging for
up to 14 hours. The scale can be operated on AC power during the charging process. The battery is
protected against over charging and the scale can remain connected to the AC power line.
