9.2 Recalibraon of Absolute pressure ranges
• Make sure that the instrument is open to atmosphere, no pressure applied to the instrument.
Press the keys SET and PEAK simultaneously for a few seconds.
P0000
Enter the and confirm with the SET-key. password 0022
1.0000
In this phase it is possible to select the true atmospheric pressure value.
It is recommended to always refer to reliable reading, such like with XA1000
of DRUCK & TEMPERATUR Leitenberger GmbH, and not to alter reading with
an incorrect value.
End
The procedure is completed.
9.3 Recalibraon of the Temperature measurement
The instrument has an internal temperature sensor with an accuracy of 1°C and a resoluon of
0.01°C. If the temperature reading does not fall within the specificaon or to improve the
performance, it is possible to calibrate the sensor.
Calibraon of the temperature sensor is performed at two different temperature points.
The first point (t1) at ambient (room) temperature, the second at a temperature of about 40°C or
50°C (t2).
Press the keys SET and PEAK simultaneously for a few seconds.
P0000
Set the with the arrow-keys and confirm with SET key. password 3126
t1
The message t1 will be displayed to indicate that the room temperature can be
calibrated. Confirm with SET key.
23.8°C
The display shows the temperature read by the instrument.
With a reference the5rmometer, measure the ambient temperature.
Correct the value displayed with the arrow-keys unl it is the same as the
reference measurement. Confirm with SET key.
t2
The message t2 will be displayed to indicate that the second temperature point
can be calibrated. Bring the instrument to the desired temperature and wait
unl the system is stabilized. Confirm with SET key.
43.7°C
The display shows the temperature read by the instrument.
With a reference thermometer measure the temperature of the chamber (pressure
port). Correct the value using the arrow-keys and confirm with SET key.
End
The procedure is complete.
