TOTAL OP -- Total Operation

POS - Accumulates when flow direction is positive only.

NET - Adds or Subtracts from Total depending upon flow

direction. Applies to transit time mode only.


SET TOTAL -- Preset Totalizer

Enter the value in user selected total units that the flow meter is

to begin totalizing.

PASSWORD -- Change the Security Password

0-9999
By changing the Security Password from 0 to some other value
(any value between 1-9999), configuration parameters will not
be accessible without first entering that value when prompted. If

the value is left at 0, no security is invoked and unauthorized
changes could be made. Access to resetting of the Totalizer is

also protected by this password.
If the FUSION password is lost or forgotten, contact the

Dynasonics factory for a universal password to unlock the meter.

20CAL -- Calibration of the 4-20 mA Output

IMPORTANT: The 4-20 mA output is factory calibrated and
typically does not require field adjustment.
The 420CAL? entry allows fine adjustments to be made to the

“zero” and span of the 4-20 mA output. Select YES to access

adjustment. To adjust the 4 mA output, a milliammeter or
reliable reference must be connected to the 4-20 mA output.
Procedure:
1. Disconnect the current loop output and connect the

milliammeter in series between the 4-20 mA output and the

recording device.

2. Using the arrow keys, increase the numerical value to

increase the current in the loop to 4 mA. Decrease the value
to decrease the current in the loop to 4 mA. Typical values

range between 40-80 counts.

3. Re-connect the 4-20 mA output circuitry as required.
