20 mA ADJUSTMENT (20mAOut)
The 20 mA adjustment is performed using the same procedure as the 4 mA adjustment While monitoring the ammeter,
adjust the 20 mA DAC value to obtain a 20 mA reading The ▲ arrow button increases the DAC value and the ►
arrow button decreases the DAC value. When a steady 20 mA reading is obtained on the ammeter, press the ENTER
button to lock in this value and move to the next parameter
4-20 mA TEST (4-20Tst)
The ER-500 monitor contains a diagnostic routine that allows the simulation of mA output values between 4 and 20 to
check output tracking At the 4-20 Tst prompt the current is shown as a flashing number Use the ▲ arrow button to
increase the simulated mA output in increments of 1 mA The ► arrow button decreases the mA output. The ammeter
should track the simulated mA output If a 4-20 mA test is not necessary, press the ENTER button once to move to the
next parameter
NOTE: N Pressing the ENTER button when the monitor is in test mode causes the monitor to exit the test mode and move on
to the next programming parameter
Linearization (Linear)
Extended Function
Enhanced accuracy is obtained by linearization of the display The linearization function accepts 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 ► arrow button to advance to the next parameter The maximum number of linearization
points is 10
Number of Points (Lin Pts)
At the Linear prompt, press the ENTER button once The linear points Lin Pts value is displayed If the number of points
is set to 0, linearization is disabled Press the ENTER button and the most significant digit of the number of points entry
begins to flash The first number can either be a 1 or a 0 only Use the ▲ arrow button to change the first digit Press the
► arrow button once to move to the least significant digit
NOTE: N If a number other than 0 or 1 is entered in this field the display flashes "Limit" indicating that an over range value has
been entered when the ENTER button is pressed
Again, the ▲ arrow button increments the value When the number of points has been input, press the ENTER button
once to move to the first linear points frequency entry
