The gas manifold assembly continually monitors gas
pressure when the Osmetech OPTI is in use. When the
pressure is less than 25 psi, the
Low Gas
warning is
displayed to indicate that the remaining gas pressure can
perform only one additional sample measurement.
The Gas expiration date is monitored based on the barcode that
was swiped into the Osmetech OPTI’s memory at the time of
the last gas canister change. This message alerts the operator
that there is 2 weeks usage remaining for the gas tank.
The operator can continue normal operation by pressing

µ
L (Osmetech OPTI CCA 120
µ
L) of clear fluid such as
QC material to perform a measurement. Sample light gates
LG1 and LG2/(LG3) in the sample measurement chamber
(SMC) detect the leading and trailing edge of the sample in
order to determine if the minimum amount of sample is
aspirated. When LG1 does not detect sample aspiration, this
message is displayed.
During battery operation of the analyzer, the Osmetech
OPTI continually monitors the battery voltage. When the
operating voltage of the battery is less than 11.8 volts and
greater than 11.2 volts a battery warning is displayed. This
informs the operator to plug in the battery charger or install a
fully charged battery prior to an interruption of system
operation.
