the cable so that its weight does not put excessive strain on the
connector (3).
5- Gauge Installation
Connection
Do not touch the inside surfaces of this gauge with bare hands,
especially the inlet flange. Fingerprints will increase outgassing in
the gauge and cause erroneous pressure readings.
Install this gauge on the vacuum system with care. If it is
necessary to reposition it, do not twist or bend the sensor by the
electronic enclosure. Disconnect the gauge, position it in the correct
position, and connect it again.
Install this gauge away from vibration. High vibration can cause
the gauge to malfunction.

The Pirani gauge can be adjusted at two points, atmospheric
pressure (ATM) and at the low pressure limit of the gauge (VAC).
The gauge automatically determines whether the conditions are at
atmosphere or under low pressure (zero). Before adjustment, the
gauge must be mounted in the same orientation and conditions
it will be used in. It must be held in these conditions for at least
10 minutes before proceeding.
To adjust the zero, be sure the gauge current pressure is below
1 x 10-4 mbar (7.6 x 10-5 Torr).

The Pirani gauge can be adjusted at two points, atmospheric
pressure (ATM) and at the low pressure limit of the gauge (VAC).
The gauge automatically determines whether the conditions are at
atmosphere or under low pressure (zero). Before adjustment, the
gauge must be mounted in the same orientation and conditions
it will be used in. It must be held in these conditions for at least
10 minutes before proceeding.
To adjust the zero, be sure the gauge current pressure is below
1 x 10-4 mbar (7.6 x 10-5 Torr).

The Pirani gauge can be adjusted at two points, atmospheric
pressure (ATM) and at the low pressure limit of the gauge (VAC).
The gauge automatically determines whether the conditions are at
atmosphere or under low pressure (zero). Before adjustment, the
gauge must be mounted in the same orientation and conditions
it will be used in. It must be held in these conditions for at least
10 minutes before proceeding.
To adjust the zero, be sure the gauge current pressure is below
1 x 10-4 mbar (7.6 x 10-5 Torr).
