4 mA Adjustment
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 Adjustment
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.
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 to advance to the next parameter. See ADDITIONAL SCALING PARAMETERS on page 16 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 will begin to flash FREQ 1. 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.
Coecient =
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 the MENU twice at the NUM
PTS prompt to exit to the LINEAR prompt. Press the RIGHT arrow 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 arrows as previously described, enter the password value. Pressing ENTER will store the password and take you back to
the RST PSWD screen.
OTE:N This password will allow the operator to manually reset totals.
