User Manual
Damping Factor
At the DAMPING prompt, press ENTER. The current damping setting will begin to flash. If the current selection is correct,
press ENTER to advance to the next parameter. The damping factor is increased to enhance the stability of the flow readings.
Damping values are decreased to allow the flow meter to react faster to changing values of flow. This parameter can take on
any value between 0…99 with 0 being the default.
Totalizer Pulse Output
The pulse output parameter can be either enabled or disabled. When enabled, this output generates 20 mS duration pulse for
every time the least significant digit of the totalizer increments. The amplitude of the pulse is dependent on the voltage level
of the supply connected to the pulse output and is limited to a maximum 30V DC.
Flow 4 mA Setting
When the loop powered option is ordered, the flow rate that corresponds to 4 mA must be set. If the current selection is
correct, press the RIGHT arrow to advance to the next parameter. If adjustment is required, press ENTER at the FLOW 4MA
prompt. The most significant digit will begin to flash. The RIGHT arrow moves the active digit one place to the right for each
press. The UP arrow increments the active digit one integer for each press. When the correct 4 mA flow rate has been entered,
press ENTER to store this value and move to the next parameter.
Flow 20 mA Setting
Follow the same programming process as the FLOW 4MA except for the flow rate setting. In this case, use the maximum flow
rate for the meter.
4-20 mA Calibration
When ordered with a 4-20 mA option, this menu item allows the fine adjustment of the 4-20 mA output. The 4 mA setting
is typically between 35…50. To set the 4 mA value, connect an ammeter in series with the loop power supply. See Figure 3.
At the 4-20CAL prompt, press ENTER. The display will now show a steady NO indication. Press UP to change to a flashing YES
display. Press ENTER to access the 4 mA fine adjustment.
