Carry out, in the following order, the INSTALLATION / STARTING UP procedure described below :
1/ Press down the ON/OFF push-button located on the front panel to start the unit. The synoptic
screen is displayed and the instrument passes into the "WARM-UP" cycle. During the warm-up cycle,
the instrument self-checks its various parameters. The "WARM UP" message blinks at the top of the
right corner of the Synoptic screen.
When all the operation parameters (pressure, temperature, voltage) are within operational limits, the
"WARM-UP" cycle is terminated.
STOP
After a specified period of time without any keyboard action (duration is
programmable in the «Configuration

Measurement mode» menu), the screen
enters stand-by mode. Pressing any key makes the screen return to display mode.
2/ Carry out Beta gauge calibration (« CALIBRATION

Beta gauge » menu).
NOTE : Calibration lasts for about 1h (for 10 cycles). Refer to section 3.3.3.1 for procedure
details.
3/ Check pressure sensors calibration (« CALIBRATION

Pressures » menu) :
Using a reference barometer, check values of upstream pressure, downstream pressure and
atmospheric pressure. They must all be equal to the atmospheric pressure read on the barometer
(pump being switched off).
Refer to section 3.3.3.4 for procedure details.
4/ Check calibration of temperature and relative humidity sensors :

In the « I2C Card(s)

RST board » menu, check the values of Atmos. temperature and Relative
humidity using the reference sensors.
