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.

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 Count Series has a level indicator as a reminder that the scale should be leveled
for accurate weighing. 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.
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 13 in figure 3-2) will remain
lit. The scale can be operated during charging, and the battery is protected against
overcharging.
During battery operation, the battery symbol indicates the battery charge level. The scale
will automatically turn off when the batteries are fully discharged.
For maximum operating time, the battery should be charged at room temperature.
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.

3.4 Accumulation and Statistics
The Accumulation feature enables manual or automatic totalizing of displayed values. Statistical
data (accumulated weight, count and number of weighments) is stored in memory for review
and printing. Accumulation works together with Check mode.
3.4.1 Accumulating Displayed Values
With ACCUMULATE set to MANUAL, place the item on the scale and press the M+ key to add
the weight to accumulation data. The ∑ pointer will keep flashing until the weight is removed.
With ACCUMULATE set to AUTO, place the item on the scale. The displayed value is
accumulated automatically. The ∑ pointer will keep flashing until the weight is removed.
3.4.2 Viewing and Clearing Statistical Data
When the pan is cleared, press the M+ key to display the statistical information. To clear the
accumulation data press the Tare key while the statistical information is displayed. The display
shows [Clr.aCC]. Press the Yes key to clear the stored data and return to current mode.
Notes: The item must be removed from the pan before the next item can be accumulated.
Only stable weights are stored to accumulation data.
Changing the mode will clear the accumulation data.
When Legal for Trade is ON, the display must return to 0 gross. Otherwise, the ∑
pointer will continue flashing. Gross loads and net loads cannot be added to
the same total. If the first load is a gross weight, future loads must also be gross
weights. If the first load is a net weight, future loads must also be net weights.
3.5 Check-Weighing

key when [wWeIGH] is displayed in the piece weight window. Use this mode to compare the
weight of items to a target weight range.

window.
3. Press the Yes key to accept the under limit value, [Over] is displayed in the weight
screen.
