1.2 Safety Precautions
Please follow these safety precautions:
Verify that the AC input voltage printed on the data label matches the local AC power supply.
Do not drop loads on the platform.
Make sure that the power cord does not pose a potential obstacle or tripping hazard.
Do not position the scale in a way that makes it difficult to pull the power plug.
Use only approved accessories and peripherals.
Operate the scale only under ambient conditions specified in these instructions.
Disconnect the scale from the power supply when cleaning.
Do not operate the scale in hazardous or unstable environments.
Do not immerse the scale in water or other liquids.
Do not place the scale upside down on the platform.
Only use weights within the scale’s capacity as specified in these instructions.
Service should be performed only by authorized personnel.

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.

2.5 Connecting Power
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 jack then connect the AC plug to an electrical outlet.
Figure 2-3A. Connect the power plug to the input jack on the back of scale.

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 charge level remaining. The indicator will automatically turn off when the batteries are fully charged.
TABLE 2-1
Symbol Charge level
0 to 10 % Remaining
11 to 40 % Remaining
41 to 70 % Remaining
71 to 100 % Remaining
Notes:
When battery symbol blinks fast, approximately 30 minutes working time is left. 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.

Positive Check
Positive check is used to determine when the material added to the scale is within the target range. In this case the UNDER and OVER limits must be positive values. (The OVER limit must be greater than the UNDER limit.)
Add material to the scale until it is within the ACCEPT (green) range.
Negative Check
Negative check is used to determine when the material removed from the scale is within the target range. In this case the UNDER and OVER limits are both negative values.
The UNDER limit must be greater than the OVER limit (for example: UNDER = -10/OVER =-15). Place the item to be weighed on the scale and press TARE.
Remove a portion of the item until it is within the ACCEPT range.
