CHAPTER 4 TESTING4.5 Print TestPrinting data to an external computer or printer requires that the communication parameters inthe RS232 submenus be set to match external device communication parameters.1. Remove all weight from the Pan.2. Tare the balance, 0.0g should be displayed3. Place a mass on the Pan.4. Press Print button, the computer or a printer should indicate the mass value as shownon the display.4.6 Testing the AC AdapterThe AC Adapters are available with different input voltages. Before testing the Adapter, makesure the Adapter rating agrees with the power source being used. All Adapters are rated withan output of 12 V AC at 1.0 Amp. Adapters can fail by having shorted internal windingsproducing low voltage output or no output at all. Measure the Voltage between Pin A and Pin Bof the Adapter (see Figure 4-6) to assure the proper voltage.Pin A Pin BNote: Measure the Voltage between Pin A and Pin BFigure 4-6.
