After pressing the analyser will count down for 5 seconds and
then return to the main display.
WARNING :
The sensors must only be reset if you are sure they
have been sampling fresh air for at least 3 minutes.
Errors in measurement will occur if the sensors are
reset during or just after sampling.

: GROSS
Allows all displayed units to be changed.
TEMP :
Choose from Centigrade, °C, or Fahrenheit, °F.
GAS :
Changes the toxic gas measurement units. Select from volumetric
readings, parts per million (ppm) or mass flow reading milligrams per
cubic meter (mg/m
3 ) .
PRESS. :
Flue draught can be displayed in millibar (mbar), hectaPascals (hPa),
millimeters water gauge (mmWG) or inches water gauge (in WG).
EFF. :
Efficiency can be selected for gross or net values. Gross efficiency
assumes latent heat of vaporisation is lost in the boiler and hence will
be lower than net efficiency. For natural gas the difference will be
approximately 11%.
Efficiency is displayed as EFF (G) or EFF (N) respectively. Should
the instrument detect that a condensing boiler is under test then it
automatically switches to a third mode that is displayed as EFF (C).
