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.

3.4 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

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.
