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.

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:

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.
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.)

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.

One or more Alarm Events are active
One or more Diagnostic Events are active
(M) Activated regardless of the Alarm, Totalizers or
other conditions. By default, relay is Disabled (not
energized)
