In most cases, you will not set up the recorder to store this units identifier. It is provided in
response to the standard measure command to eliminate confusion as to the computation used to
come up with the final value.
Other Measurements
The SDI-12 standard allows for other measurement commands such as M1, M2 etc., other current
measurement commands such as C1, C2, etc., other non-concurrent measurements with CRC-16
such as MC1, MC2, etc, and other concurrent measurement with CRC-16 such as CC1, CC2, etc.
This unit maintains symmetry across all four classes of commands, that is, it returns the same
information to a C1 as it does to a M1 or a MC1 or a CC1. The AccuBubble supports the following
optional measurement commands:
aM1!
aC1!
aMC1!
aCC1!
measure psi using factory calibration. Do not apply any user
scaling, field calibration or offsets. This returns 1 value and
the units are fixed to psi.
aM2!
aC2!
aMC2!
aCC2!
measure temperature (Celsius or Fahrenheit). This returns
two values: the temperature and the units. The units will be 0
for Celsius and 1 for Fahrenheit.
aM3!
aC3!
aMC3!
aCC3!
measure user scale, user offset, field calibration offset. Use
this if you want to view the user-entered values that can affect
the value returned by the M, C, MC, and CC commands.
aM4!
aC4!
aMC4!
aCC4!
measure calibration lab scale and offset. Use this if you want
to view the calibration lab values that can affect the value
returned by the M, C, MC, and CC commands.
aM5!
aC5!
aMC5!
aCC5!
measure the quadrature scale factor, quadrature threshold,
quadrature step rate, and operating mode for the analog and
quadrature outputs
(
Version 2.0
and higher
.)
aM6!
aC6!
aMC6!
aCC6!
Measure temperature and pressure. The output is the
concatenation of the M2 and M commands. Temperature,
temperature units, Pressure, Pressure units.
(
Version 2.0
and higher
.)
aM7!
aC7!
aMC7!
aCC7!
Measure psi and degrees C using factory calibration. Do not
apply any user scaling, field calibration or offsets. This
returns two values and the units are fixed to psi and degrees
C.
Remember to issue the aD0! command after the measurement is complete in order to retrieve the
data.
