Figure 2-1. Installing sub-platform and metal pan
2.3 Selecting the Location
Use the scale on a firm, steady surface. Avoid locations with excessive air current, vibrations,
heat sources or rapid temperature changes. Allow sufficient space around the scale.
2.4 Leveling the Equipment
The Ranger Series has a level indicator as a reminder that the scale should be leveled for
accurate weighing. There is a level bubble in a small round window on the front of the scale.
To level the scale, adjust the feet so the bubble is centered in the circle.
Be sure the equipment is level each time its location is changed.

AC power is used to power the scale when battery power is not needed. First, connect the AC
power cord (supplied) to the power input receptacle then connect the AC plug to an electrical
outlet.
Figure 2-3A. Connect the power plug to the Figure 2-3B. Connect AC power
input receptacle on the back of scale. plug to the proper AC supply.
2.5.1 Battery Power:
The scale can be used on AC power immediately. Allow the battery to charge for 12 hours
before using the scale on battery power. The Scale will automatically switch to battery
operation if there is a power failure or the power cord is removed. With AC power, the scale
is constantly charging, so the battery charge indicator (see item 10 in table 3-2) will remain
lit. The scale can be operated during charging, and the battery is protected against
overcharging.
For maximum operating time, the battery should be charged at room temperature.
During battery operation, the battery symbol indicates the battery charging status. When
charging, the symbol will blink slowly and when fully charged the symbol will be turned off.

When [lo.bat] is displayed, the scale will shut off.
Charging the scale must be performed in a dry environment.
CAUTION: Battery is to be replaced only by an authorized Ohaus service
dealer. Risk of explosion can occur if the rechargeable battery is replaced
with the wrong type or if it is not properly connected. Dispose of the lead
acid battery according to local laws and regulations.
