B2800 Simplified 4-20 mA Programming Instructions

FLOW 4 mA Setting

When the loop powered option is ordered, the flow rate that corresponds to 4 mA must be set Zero is default flow rate for this

setting If the current selection is correct, press ENTER once to advance to the next parameter If adjustment is required, use

the RIGHT arrow to select the position of the number you wish to change Then use the UP arrow to increment the number

Once you have completed this step, press ENTER to advance to the next parameter

FLOW 20 mA Setting

The flow rate that corresponds to 20 mA must be set next The turbine meter’s maximum flow rate is the default value If the

current selection is correct, press ENTER once to advance to the next parameter If adjustment is required, use the RIGHT

arrow to select the position of the number you wish to change Then use the UP arrow to increment the number Once you

have completed this step, press ENTER to advance to the next parameter

4-20 mA Calibration

When ordered with a 4-20mA option, this menu item allows the fine adjustment of the 4-20 mA output The 4 mA setting

is typically between 35 and 50 To set the 4 mA value, connect an ammeter in series with the loop power supply At the 4

mA OUT prompt, adjust the 4 mA value to obtain a 4 mA reading on the ammeter The UP arrow increments the value and

the RIGHT arrow decrements the value When a steady 4 mA reading is obtained on the ammeter, press ENTER to lock

in this value and move to the 20 mA adjustment 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 the arrow keys change the simulated mA output in increments of 1 mA The ammeter should track

the simulated mA output If a 4-20 mA test in not necessary, pressing ENTER once will escape the testing at any time

If your B2800 Flow monitor was ordered with a Blancett turbine flow meter, the 4-20 mA was programmed and

factory calibrated
