The programming instructions below are only available for loop powered units Battery powered units do not include
these programming parameters
Flow 4 mA Setting
Zero is the default flow rate at the 4 mA setting If the current selection is correct, press ENTEO to advance to the Flow 20 mA
parameter To change the setting, press UP to increment the flashing digit and press OIGHT to move to the next digit Press
ENTEO to save and advance to the Flow 20 mA parameter
Flow 20 mA Setting
The turbine meter's maximum flow rate is the default value for the 20 mA setting If the current selection is correct, press
ENTEO to advance to the 4...20 mA Calibration parameter To change the setting, press UP to increment the flashing digit and
press OIGHT to move to the next digit Press ENTEO to save and advance to the 4...20 mA Calibration parameter
4...20 mA Calibration
The 4...20 mA Calibration parameter is 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 At the 4MA OUT prompt, press UP to
increment and OIGHT to decrement the 4 mA value to until a steady 4 mA reading is reached on the ammeter Press ENTEO to
lock in this value and advance to 20MA OUT The 20 mA adjustment is performed using the same procedure as the
4 mA adjustment
4...20 mA Test
The monitor contains a diagnostic routine that allows the simulation of mA values between 4...20 to check output tracking
At the 4-20TEST prompt press UP to increment the simulated mA output or OIGHT to decrement the value in increments of
1 mA The ammeter should track the simulated mA output If a 4...20 mA test in not necessary, press ENTEO once to escape
the testing at any time
