OPERATION GA-40 T plus

ENTER - switches between AVERAGED VALUES and CURRENT VALUES

C - the display on the AVERAGED VALUES screen gets "synchronised" (a row of

strokes appears instead of the values) and a new averaging session starts. The

measurement results are displayed after the whole cycle is finished.

DATA - switches on/off the HOLD function ("freezing" the current values )

{{ If a continuous storage recording is taking place the analyser won't synchronise

the averaging process ( not to interfere with the continuity of storage )

5.3.3 The Averaging Process

The analyser is capable to display all results, measured or calculated, either as current value or as averaged

value. The averaging time can be selected in a range of 10 seconds to 60 minutes. If a time of 1 min was set,

the averaged results over that time would be shown on the display. During the averaging process a row of

strokes appears on the screen, since there are no results to display.

If measurement parameters are changed during the averaging process, the averaging cycle has to be re-started.

In case the data storage is activated it is stopped as well.

The following incidents cause an interruption of the averaging cycle.

G change of averaging time

G change of reference Oxygen

G change of fuel

G switching the instrument to STANDBY mode

G pressing "C"

5.4 Pressure/Draft Measurements

It is possible to measure differential pressure with the GA-40 T plusplus . To do so the stubs PRESSURE (-) and

(+) on the front plate are used. The measurement is performed as follows:

MENU - select the main MENU

Â and Ã - move the cursor to PRESSURE

Á - select the option. The following screen appears

œ PRESSURE

[hPa] 12.54

[mm H2O] 128

[PSI.] 5.25

GAS TEMP.: 563 °C

C - ZEROING

The current pressure and gas temperature are displayed on the screen. The last line shows the command

ZEROING. By pressing this key the sensor is set to zero, e.g. the current value will be taken as zero

value.Please be aware that the sensor has to be zeroed before the measurement.
