Item weighing instrument ad-8923-bcd baud rate 600, 1200, 2400*, 4800, 9600, 19200 bps data bits, parity 7 bits even...
Page 8: 3.3. Turning The Power On
6 3.3. Turning the power on as a power supply, an external 24-vdc power supply (24 vdc±10% / 700ma) or a 12-vdc ac adapter can be used. Note when the ad-4212c is used, connecting power to either the ad-8923-bcd or the ad-4212c will supply power to both devices. So, instead of the ad-8923-bcd, using ...

8 3.4. Operation z displays the data transmitted by the weighing instrument connected. Z the ad-8923-bcd key functions when connected to a weighing instrument are listed below: (e.G. When the ad-4212c is connected) keys of the ad-8923-bcd model on:off cal sample print mode re-zero ad-4212c switches ...
Page 11: Calibration Procedure
9 calibration procedure calibrates the ad-4212c using the calibration weight. Operation 1. Warm up the ad-4212c for 30 minutes or more with nothing on the pan. 2. Press the cal key. Cal 0 is displayed. Z if you want to cancel calibration, press the cal key. The display will return to the weighing mo...
Page 12: 4. Function Setting
10 4. Function setting function setting specifies the ad-8923-bcd performance. The parameters are stored in non-volatile memory, and are maintained even if the power line or ac adapter is removed. The function setting menu consists of two layers. The first layer is the “class” and the second layer i...
