Badger Meter B2800 - Manual (Page 11)

Linearization
Enhanced accuracy can be obtained by linearization of the display The linearization routine will accept a maximum of ten
points Linearization requires additional calibration data from the meter to be used with the monitor Typically, calibration
information can be obtained in three, five, and ten points from the flow meter’s manufacturer If linearization is not needed,
press the RIGHT arrow key to advance to the next parameter See ADDITIONAL SCALING PARAMETERS on page 18 for
more information
Number of Points
At the LINEAR prompt, press ENTER The NUM PTS value will be displayed Press ENTER to set the number of points to be
used Again, the UP arrow increments the value and the RIGHT arrow moves the cursor between digits When the number of
points has been input, press ENTER to move to the first linear segment
Press ENTER and the first linear point’s frequency input, FREQ 1 will begin to flash Enter the frequency for the first linear point
using the arrow keys When the frequency value input is complete, press ENTER again to change to the coefficient value for
the first linear point
Coefficient
The coefficient is the value applied to the nominal K factor to correct it to the exact K factor for that point The coefficient is
calculated by dividing the actual K factor for that point by the average K factor for the flow meter
Coefficient =
Average K Factor
Actual K Factor
At the COEFF prompt, enter the coefficient that corresponds to the frequency value previously entered Press ENTER to move
to the scaling point
Continue entering pairs of frequency and coefficient points until all data has been entered Press MENU twice at the NUM
PTS prompt to exit to the LINEAR prompt Press the RIGHT arrow key to move to the next parameter
Password
Password protection prevents unauthorized users from changing programming information Initially, the password is set to all
zeros To change the password, press ENTER at the PASSWORD prompt The first digit of the password will begin to flash Using
the arrow keys as previously described, enter the password value Pressing ENTER will store the password and take you back
to the RST PSWD screen
OTEE: N This password will allow the operator to manually reset totals
Reset Password
Reset password protection prevents unauthorized users from manually resetting the flow monitor’s accumulated totals
Initially, the password is set to all zeros To change the password, press ENTER at the RST PSWD prompt The first digit of the
password value will begin to flash Using the arrow keys as previously described, enter the password value Pressing ENTER
once will store the password and take you back to the METER size screen Pressing MENU exits the PROGRAM mode The
B2800 flow monitor is now ready to use with its companion meter
OTEE: N Entering a password in the PASSWORD screen and leaving the password blank in the RST PSWD screen allows for total
resets (not requiring a password), but restricts programming modification
Reset Total
o reset the monitor’s total display, in RUN mode, press MENU and ENTER simultaneously until TOTAL RST starts to flash The
TOTAL RST will stop flashing and the display will return to the RUN mode at the conclusion of the reset procedure
Store Total
The current total can be manually stored in the monitor’s flash memory This procedure may be desirable prior to changing
the settings or replacing the battery Press and hold ENTER for two seconds The display will respond with a flashing
TOTALSVD and then return to the RUN mode
