MISCELLANEOUS PARAMETERS
P999 Front panel cal/cfg access (FPA)
Enable or disable (ON or OFF) this function; see the “Front Panel
Configuration/Calibration/Diagnostic Access (FPA)” section of this manual.
ANALOG OUTPUTS
The EI’ series furnishes an analog 4-20mA (milliamp) signal for transmission to a remote
system such as a SCADA or RTU for each channel (up to four). From the factory, the
calibration is within 1.5% of 4mA and 1.5% of 20mA or better. Therefore, it is recommended
that one performs a 4-20mA calibration adjustment for each channel if a more accurate
matching between the meter and user system is required.
To access the analog output calibration/test mode, close S1-2 (S1-1 & S1-4 are open) or use
the FPA sequence. These parameters are used to calibrate the 4 - 20mA analog output
points for each channel. See the table below for push-button functionality. NOTE: Left zero,
left select, right zero & right select have no function in Analog Output Configuration.
EI-2000
Left, up and down arrow pushbuttons
Select a parameter
Right, up and down arrow pushbuttons Alter the value of the parameter
EI-1000
UP/DOWN arrows select a parameter.
To alter the value of a parameter, press the SELECT pushbutton. Use the
UP/DOWN ARROWS pushbuttons to set the desired value and then press the
SELECT pushbutton when finished.
PARAMETER EI-1000: Ao.tESt
PARAMETER EI-2000: Ao t xx.xx
This parameter tests both Digital to Analog Converters using ten,
linear 1.6mA steps from 4.00 mA to 20.00 mA.
The analog outputs are active (self powered). Therefore, the load must be passive
(voltage/potential free) so no damage occurs to the EI-2000S-CPU or the user’s system. The
“R LOAD” resistance can range from 0 to 510 ohms. When one is calibrating the analog
outputs, the “R LOAD” represents the DMM or 4-20mA calibrator device.
Note: The –L & -R (terminals 1 & 3) are connected and this must be taken into
consideration when connecting the load to the analog outputs. Refer to schematic
above.
