When this message is displayed the
TEMPEST 50
unit will not
perform any subsequent emissions measurements, update the time
or allow any other parameters to be changed. This enables the user
to hold data or print-out several copies of a set of readings.
Pressing again will turn the ‘DISPLAY HOLD’ off.

O2 STATUS HIGH indicates that the oxygen sensor is producing
sufficient output when placed in air. If the status reads LOW then
the oxygen sensor may require replacement (see back page). The
other line of data is the draught measurement, when the pressure
sensor is fitted as an option.

INTA(KE)
The temperature of the air entering the combustion
chamber if an auxiliary probe is fitted.
STAC(K)
The temperature measured by the flue gas probe.
AMBIENT
The temperature measured by a sensor in the
TEMPEST 50
NETT
The difference between the intake (or ambient if no
intake temperature) and the stack temperatures.
