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

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.

3.3 Counting

Ranger Count 3000 has three display areas. Weight, Piece Weight and Count information are displayed in these areas respectively.

3.3.1 Preset tare

Enter a value with the numeric keypad. The value will be displayed in the Count window. Pressing Tare key, the value in current unit will then be saved as the preset tare.

To clear the tare value, clear the pan and press Tare key.

3.3.2 APW Establishment

If there is no APW established, both the piece weight display and the count display will show 0.

Positive Sampling:

1. Place the sample on the pan.

2. Input the sample size with the numeric keypad. The value is displayed in the count window.

Alternatively the Sample key can be used instead. Pressing the Sample key and [------] is displayed in the count window. Then input the sample size value (only

integer).

3. Press the Sample key, [------] will be displayed in both the piece window and the count

window.

4. The established APW and count will be displayed.

Negative sampling:

1. Place container with the samples on the pan.

2. Tare the scale, a NET 0 will be displayed.

3. Remove the samples from the container; weight window will now display a negative net reading.

4. Input the sample size with the numeric keypad. The value will be displayed in the count window.

Alternatively the Sample key can be used instead. Pressing the Sample key and [------] is displayed in the count window. Then input the sample size value (only

integer).

5. Press the Sample key, [------] will be displayed in both the piece window and the count

window.

6. The established APW and count will be displayed.

EN-8 Ranger™ Count 3000 Series

Entering a known APW:

1. Press the APW key, [------] will be displayed in the piece window

2. Input the APW value.

3. Press the APW key, the new APW value will be displayed in piece weight window.

3.3.3 Simple Counting

1. After a valid APW is established, if required place a container on the pan and press Tare.

2. Place the sample on the pan.

3. The quantity will be displayed in the count window.

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

Press and hold the Target key, [Check] is displayed in the weight window. Release the Target key when [wWeIGH] is displayed in the piece weight window. Use this mode to compare the

weight of items to a target weight range.

1. Press the Target key, [Under] is displayed in the weight screen. The previous under limit

will is displayed in the piece weight screen.

2. Input the target weight with the numeric keypad. The value will be displayed in the count window.

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

screen.

4. Repeat step 2 and 3 above to set the over limit.

Ranger™ Count 3000 Series EN-9

5. If required, place an empty container on the pan and press Tare.

6. Place sample material on the pan or in the container. If the sample weight is under the target weight range, the yellow LED will light. If the sample is within the target weight range, the green LED will light. If the sample is over the target weight range, the red LED will light.

3.6 Check-Counting

Press and hold the Target key, [Check] is displayed in the weight window. Release the Target key when [Count] is displayed in the piece weight window.

1. Press the Target key, [Under] is displayed in the weight screen. The previous under limit

will is displayed in the piece weight screen.

2. Input the sample size with the numeric keypad. The value will be displayed in the count window.

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

screen.

4. Repeat step 2 and 3 above to set the over limit.

5. If required, place an empty container on the pan and press Tare.

6. Place sample material on the pan or in the container. If the sample quantity is under the

target pieces range, the yellow LED will light. If the sample is within the target pieces range, the green LED will light. If the sample is over the target pieces range, the red LED

will light.

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.

Zero Check

Zero check is used when comparing subsequent samples to an initial reference sample. In this case, the UNDER limit must be a negative value and the OVER limit must be a positive value.

Place the reference item on the scale and press Tare. Remove the reference sample and place

the item to be compared on the scale to determine if it is within the ACCEPT range.
