33 Master meter incompatible
configuration
For a master meter prover, both the line meter and
the master meter must be compatibly configured,
including identical settings of:


System of measurement units (US, SI)

Liquid density units (kg/m3, Rd/60, °API)

Product group


Measured quantity (gross volume pulses)

Reference conditions (base temperature and
pressure)

API calculation options (selection of density,
temperature, and pressure corrections)


For product group 8, Special applications, the
coefficient of thermal expansion Alpha
38 Master meter in calibration The master meter has at least one process input in
calibration mode. Ensure that all process inputs are
live before attempting to use the master meter for
proving.
39 Master meter not enabled The master meter is not enabled.
51 Invalid prover parameter For a traditional (non-master-meter) prover, the base
prover volume (register 65036) must be greater than
zero, and, if the prover is single-walled, the inside
diameter, wall thickness, and modulus of elasticity
(registers 65038, 65040, and 65042) must all be
greater than zero.
52 Invalid prover controls Some undefined bits in the at-enable controls
(register 65306 bits 0 through 7) have been set.
