4- Technical Data (ctd)
The Pirani gauges AP/APN 2004 have been designed for vacuum
measurements of gases in the pressure range of 1000 mbar to
5x10-4 mbar.
They are active gauges. The gauges of 0/10V type can be oper-
ated with an Adixen controller (ACS 2000 or ACM2000) or as a
stand alone gauge sending a signal directly to other equipment. The
gauges of RS485 type can be operated only with RS485 customer’s
equipment.
These gauges must not be used for measuring flammable or
combustible gases which react in air.

4- Technical Data (ctd)
The Pirani gauges AP/APN 2004 have been designed for vacuum
measurements of gases in the pressure range of 1000 mbar to
5x10-4 mbar.
They are active gauges. The gauges of 0/10V type can be oper-
ated with an Adixen controller (ACS 2000 or ACM2000) or as a
stand alone gauge sending a signal directly to other equipment. The
gauges of RS485 type can be operated only with RS485 customer’s
equipment.
These gauges must not be used for measuring flammable or
combustible gases which react in air.

4- Technical Data (ctd)
The Pirani gauges AP/APN 2004 have been designed for vacuum
measurements of gases in the pressure range of 1000 mbar to
5x10-4 mbar.
They are active gauges. The gauges of 0/10V type can be oper-
ated with an Adixen controller (ACS 2000 or ACM2000) or as a
stand alone gauge sending a signal directly to other equipment. The
gauges of RS485 type can be operated only with RS485 customer’s
equipment.
These gauges must not be used for measuring flammable or
combustible gases which react in air.

contaminated. Adhere to any relevant regulations and take the
necessary precautions when handling contaminated parts.
The 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).

Contaminated parts.
Contaminated parts can be detrimental to health and the
environment. Before working on any parts, find out if they are
contaminated. Adhere to any relevant regulations and take the
necessary precautions when handling contaminated parts.
The 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).

Contaminated parts.
Contaminated parts can be detrimental to health and the
environment. Before working on any parts, find out if they are
contaminated. Adhere to any relevant regulations and take the
necessary precautions when handling contaminated parts.
The 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).

Contaminated products (e.g. with radioactive, toxic, caustic
or microbiological hazard) can be detrimental to health and the
environment. Products returned to the manufacturer should be
cleaned and free of harmful substances. Be sure to follow the
shipping regulations of all involved countries and forwarding

Contaminated parts.
Contaminated parts can be detrimental to health and the
environment. Before working on any parts, find out if they are
contaminated. Adhere to any relevant regulations and take the
necessary precautions when handling contaminated parts.
The 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).
