Metex 3200U Ultrasonic Flow & Level Monitor - Manual (Page 3)

QUICK BENCH TEST:
Connect Sensor to the T.DUCER terminals as shown below, then apply Power. When properly connected
a soft clicking can be heard from the sensor and figures will show on the large LCD display. Test
operation of the Ultrason by holding the sensor steadily and aiming at a flat, stable target 12 to 28" (305
to 711 mm) away from the end of the sensor. Allow a few seconds for the Ultrason to lock onto the
target before displaying its distance. The Ultrason will now display distance in ft or cm (factory
calibration).
CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100-130VAC 50/60Hz (2 amp
fuse is recommended). No adjustments are necessary for any voltage in this range. Optional 230VAC
requires power input between 200-260VAC 50/60Hz. (See OPTIONS section of this manual for
connection of optional 12VDC or 24VDC power input).
IMPORTANT NOTE: To comply with CSA/NRTL standards, AC power input and relay connection
wires must have conduit entry to the instrument enclosure.
