PN-Series Manual 2.4. Turning on the Balance and Self-testing 1. Connect the AC adapter to an available wall socket and plug the other end of the cable into the balance. 2. Press the ON / OFF key to turn the scale on. A display test will be performed (5 seconds). 3. Once the display shows “0.0g” the balance is ready to use. 4. To turn the scale off, press the ON / OFF key.
PN-Series Manual 3. OPERATION 3.1. Sample Weighing 1. Press TARE / ZERO to make the balance return to zero. 2. Load the sample onto the scale pan. 3. The weight is stable when g (depending on which weighing unit is active) appears on the display. 3.2. Weighing with a container Sometimes it is necessary to weigh an object (such as a liquid) using a container. To display just the weight of the contents (net weight) and not the whole combined weight (gross weight), the TARE button is used. 1.
PN-Series Manual 2. Clean the weighing pan and press TARE to re-zero the balance. 3. When the balance is stabilized press and hold the CAL button for 5 seconds. 4. The display will show “-CAL-” then the required weight will flash on the display. 5. Place the calibration weight onto the center of the platform and wait for the display to stop flashing. 6. You may now remove the weight. The scale will return to normal weighing mode 3.6.
PN-Series Manual 4. APPENDIX 4.1. RS232 Serial Data Communication This balance has a Bi-Directional RS232 port for communication with a PC.
PN-Series Manual 4.4. Care & Maintenance Please read all operating instructions carefully before use. Scales are precision instruments and should always be handled with proper care. To ensure years of reliable service, keep these simple tips in mind: • Do not exceed the scales maximum capacity. Overloading your scale can permanently damage it! • Avoid exposure to extreme heat or cold. Scales perform best at normal room temperature. If temperatures have changed dramatically, recalibration may be necessary.
