RS-232C Interface Instructions

This section describes the interface for outputting the BC-418 Body Composition Analyzer measurement results as	GB
RS-232C signals to personal computers and other external devices.

mCAUTION Only connect IEC950-compliant computers to the BC-418.

Nothing appears on the display after		• Please confirm that the Control Box is properly connected to the AC
pushing [	] key		Adapter and the AC Adapter is properly connected to the cable.
E-01 is displayed.		• E-01 is displayed when the impedance shows an abnormal value
			compared to height and weight.
			Please make sure that measurement was carried out with bare feet, the
			electrodes or the soles of the feet were clean, and the feet were correctly in
			contact with the electrodes. If the feet are dry or have calluses, place water on
			the electrodes before stepping on the unit.
		•	It is possible that the body fat ratio exceeds the measuring capacity.

	•	Please refer to the readings of other parts for the body fat.
E-11 is displayed.	•	E - 11 is displayed when there is a loose connection between the control
		box and the weighing platform.
	• Confirm that none of connections between the scale and control box are
		loose or unplugged.
	• There may be excessive vibration which will disturb the measurement process.
E-12, 13 or 14 is displayed.	• The equipment requires readjustment.
E-16 is displayed.	•	Measurement is not possible because impedance is unstable. In order to
		improve electrical conductivity, please clean the soles of the feet or
		place water on the electrodes before using the equipment.
