Instruction Manual

ADDITIONAL SCALING PARAMETERS
OTE:N The programming instructions below are only available for loop powered models. Battery powered models will not
include these programming choices.
OTE:N If the B2800XP flow monitor was ordered with a Blancett turbine flow meter, the 4…20 mA was programmed and
factory calibrated.
B2800XP Simplied 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 the default flow rate for
this setting. If the current selection is correct, press ENTER 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 meters maximum flow rate is the default value. If the
current selection is correct, press ENTER 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 4-20 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. 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 4-20 TEST 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 is not necessary, pressing ENTER will escape the testing at any time.
