CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100 to 240 VAC 50/60Hz. No
adjustments are necessary for voltages within this range.
Optional DC: 9-32 VDC. Connect to + and - terminals.
Optional Thermostat and Heater modules are available rated for 115 VAC or 230 VAC.
IMPORTANT NOTE: To comply with CSA/UL electrical safety standards, AC power input and relay
connection wires must have conduit entry to the instrument enclosure. Installation requires a switch,
overcurrent fuse or circuit breaker in the building (in close proximity to the equipment) that is marked
as the disconnect switch.
Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel
should access connections.
Note: Use of instrumentation over 40°C ambient requires special field wiring.

MAIN DISPLAY
The main display shows the units selected from the Units/Mode menu,
Level, Range, Flow, HRT, and Volume rate being measured, TOTALIZER
and RELAY states. The OCF 6.1 will start-up with this display.
MESSAGE ICON
Press  from the main display to view status of the data logger and
error/warning messages provided by the instrument. The Message Icon will
appear on the main display if error messages are being generated by the
instrument. Refer to the manual section Error/Warning Messages for a
description. Press  to return to the main display.
STATUS
Press  from the main display to view instrument status. Range will be
displayed in linear units.
Range Displays the current range measurement. The distance
between the sensor face and the surface being measured.
Level Displays the current level measurement. The difference
between the Max Range programmed in the Calibration
menu and the measured range.
Flow Displays the current flow rate in engineering units set in
the Units/Mode menu.
Min Flow Displays the minimum flow rate set in the Calibration
menu. Flow rates below the Min Flow will be shown as 0
on the main display.
Echo Confidence Displays Echo Confidence in percentage. 100% is ideal,
but any percentage other than 0% is normal and means
that echoes are being measured. Echo Confidence less
than 100% means that not all echoes are returning to the
sensor, which could be because of surface turbulence, a
sensor not perpendicular to the water surface, foam,
grease, or vapors in the atmosphere.

24 HR LOG
Press  from the main display to view a formatted flow report from
instruments with a built-in data logger. Press  to scroll down one day or
repeatedly to scroll to a specific date. Up to 365 days can be stored. Newest
date will overwrite the oldest. Press  to return to the main display.
PASSWORD
The Password (a number from 0000 to 9999) prevents unauthorized access
to the Calibration menu.
From the Main display press  to get to Password. Factory default
