The DPM series Mass Flow Meters are equipped with calibrated 0-5Vdc, 0-
10Vdc, and 4-20 mA output signals. The following options are provided for
analog output:

The DPM analog output calibration involves calculation and storing the
offset and span variables in the EEPROM based on two calibration points
(0 and 100% F.S.). The 0-5 and 0-10 outputs have only scale variables,
and the 4-20 mA output has offset and scale variables.
CAUTION: The 4-20 mA current loop output is self-powered
(sourcing non-isolated type). Do NOT connect an external voltage
source to the output signals. (See Section 3.2 for proper wiring
connections.)
NOTE
: Before changing “Analog Output Interface” mode, make sure
the load impedance is within the corresponding limits stated above.
Failure to do so might cause damage to the analog output circuitry or
result in erroneous readings.
NOTE: Relay terminals are accessible via the DPM meter’s 8-pin
MiniDIN connector (pins 1 and 2) and have maximum 48VDC voltage
and 0.4A current ratings. See Figure 1 and Table I for proper wiring
connections.
