Badger Meter B2800 - Manual (Page 10)

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 of the key The UP arrow increments the active digit one integer for each press of the key 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 the UP arrow to change to a
flashing YES display Press ENTER to access the 4 mA fine adjustment

4 mA Adjustments
While monitoring the ammeter, adjust the 4 mA value to obtain a 4 mA reading 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
20 mA Adjustments
The 20 mA adjustment is performed using the same procedure as the 4 mA adjustment While monitoring the ammeter,
adjust the 20 mA value to obtain a 20 mA reading The UP arrow increments the value and the RIGHT arrow decrements
the value When a steady 20 mA reading is obtained on the ammeter, press ENTER to lock in this value and move to the
next parameter
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 one mA The ammeter should track
the simulated mA output If a 4-20 mA test is not necessary, press ENTER to move to the next parameter
