Adding a second weight will repeat the process. While the weight is on the scale it is permissible to press the PRINT key to store the value immediately. In this case the scale will not store the value when the weight is removed. The totals can be viewed as above. In all cases the scale must return to zero or a negative number before another sample can be added to the memory. More product can then be added and PRINT pressed again. This can continue for up to 99 entries, or until the capacity weight display is exceeded. - 9 - QHW digital weighing scales user’s guide SECTION 7 BATTERY OPERATION The scales can be operated from the battery if desired. The battery life is approximately 100 hours. When the battery needs charging the arrow above the low battery symbol under the weight display will turn on. The battery should be charged as soon as the arrow above the symbol is on. The scale will still operate for about 10 hours after which it will automatically switch off to protect the battery. To charge the battery simply plug into the mains power. The scale does not need to be turned on. The battery should be charged for 12 hours for full capacity. Just under the quantity display is an LED to indicate the status of battery charging. When the scale is plugged into the mains power the internal battery will be charged. If the LED is green the battery has a full charge. If it is Red the battery is nearly discharged and yellow indicates the battery is being charged. As the battery is used it may fail to hold a full charge. If the battery life becomes unacceptable then contact your distributor . - 10 - SECTION 8 RS-232 OUTPUT The QHW Series of scales can be ordered with an optional RS-232 output.
