Password Protection
A password can be set for programming security to prevent unauthorized
changes to the programmed parameter settings.
Input 1 is set to 4 mA
Display 1 is set to 0.0
EASY PROGRAMMING AND SETUP
DPM-400s can be programmed and setup either by using the front panel
buttons or free, PC-based software with USB interface.
Front Panel Buttons for Easy Setup, Programming,
and Other Functions
DPM-400 process meters include four front panel buttons
for setup and programming. The front panel buttons along
with the dual-line display makes the DPM-400 easy to set
up & program. Three of these buttons are also function
keys that can be programmed to trigger certain events
(i.e. acknowledge alarms, reset max and/or min, disable/
enable output relays, or hold current relay states), provide
direct menu access points, and more.
One feature that makes the DPM-400s particularly easy to
set up and program is that they can be scaled without ap-
plying a calibrated or known input. The user simply enters
the desired values for Input 1 and Input 2 (for instance 4.000 and 20.00
mA) and the corresponding display values for these inputs (for instance
0.0 and 2000.0)
Round Horizontal Tank Linearization
This function automatically calculates the volume in a round horizontal
tank with flat ends.
Square Root Linearization
The square root function can be used
to linearize the signal from a differen-
tial pressure transmitter and display
flow rate in engineering units.
Multi-Point Linearization
Meters are set up at the factory for linear function with 2-point linear-
ization. Up to 32 linearization points can be selected for the scaled
value under the linear function. Multi-point linearization can be used to
linearize the display for non-linear signals to convert level to flow using
weirs and flumes with complex exponent.
Programmable Exponent Linearization
The programmable exponent can be used to linearize the signal from
level transmitters in open-channel flow applications using weirs and
flumes.
FLOW
SIGNAL INPUT CONDITIONING
To satisfy applications that require scaling in ways other than the usual
2-point linear method, the DPM-400 can also be scaled for square
root (DP flow), programmable exponent (open channel flow) or round
horizontal tank volume calculation.
Loop-Powered Isolator for General Purpose Areas
The DPM-400 can be used as a loop-powered isolator for the 4-20
mA signal in general purpose areas with the added benefit of a digital
readout to display the process variable.
