Connect the gauge to the installation using appropriate fitting
accessories (1) (from the Adixen product catalog).
Connect the cable (2). Use cable ties or other methods to support
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.
This gauge is designed to operate in any orientation. Install the
gauge horizontally for higher accuracy.
Install this gauge away from drastic temperature changes (away
from any heat sources or fans) for higher accuracy.
Do not exceed the receivable maximum pressure ( 4 p. 4). If
the maximum pressure of the gauge is exceeded, it can lead to gas
leakage and cause injury.
Do not open the installation on which a gauge is installed when
the internal pressure is above 1 bar. Internal components may be
ejected and cause personal injury.
Do not use this gauge with corrosive, toxic, flammable or
explosive gasses.
Do not heat this gauge beyond 70 °C. Disregarding this instruction
can cause damage to the gauge circuits or a vacuum leak.

The crystal gauge must be adjusted to atmospheric (ATM) and
low pressure (VAC). If the hot cathode filament is ON and
pressure is below 1x10-4 mbar, VAC is adjusted automatically
every 5 minutes. When the filament is OFF (input DSBL activated)
and the gauge head is cold, manual adjustment is required. The
gauge automatically determines if it works at atmospheric or low
pressure. Before adjustment, the gauge must be mounted in the
same orientation and conditions it will be used in. It must be held
under these conditions for at least 10 minutes. To adjust zero, be
sur the gauge current pressure is below 1x10-4 mbar (7.6x10-5

Parts on a vacuum processing system can be contaminated with
material that is detrimental to health and environment.
Before removing this gauge, confirm whether or not the gauge is
contaminated with any harmful gasses or vapors. If it is contaminated
with any harmful substances, be sure the gauge and equipment are
purged and cleaned thoroughly before removal of the gauge.
Take the necessary precautions when handling contaminated parts,
refer to 9 p. 13.
7- Gauge Removal
Outgassing from the electrode system of the hot cathode gauge
can affect the measurement values or make them unstable.
Degassing removes absorbed gasses from these elements
by heating the electron collector grid to 70 °C by electronic
bombardment. Degassing normally lasts 3 minutes but can be
aborted.
This function is available when the pressure is below 5x10-3
mbar (pressure recommended < 1x10-5 mbar). It is activated
when +24 V is applied to Pin 5 of the gauge.
DGS degassing
function
This function deactivates the hot cathode gauge, allowing only
the crystal gauge to operate. This function is activated when
+24 V is applied to Pin 3 of the gauge.
DSBL Disable function

Use this procedure to reinitialize the electronics. The electronics must be reinitialized before
mounting a sensor if either of them is being replaced. To do this:
1- Attach the cable to the electronics.
2- Apply power, the ‘power‘ indicator will blink red after several seconds.
3- Keep ATM/VAC button depressed until the ‘power’ indicator lights orange before to blink
red again. 4- Remove power from the electronics. 5- Attach the sensor element.
6- Re-apply power to the gauge. 7- Calibrate the gauge ( 6 p. 9)

Parts on a vacuum processing system can be contaminated with
material that is detrimental to health and environment.
Before removing this gauge, confirm whether or not the gauge is
contaminated with any harmful gasses or vapors. If it is contaminated
with any harmful substances, be sure the gauge and equipment are
purged and cleaned thoroughly before removal of the gauge.
Take the necessary precautions when handling contaminated parts,
refer to 9 p. 13.
7- Gauge Removal
Outgassing from the electrode system of the hot cathode gauge
can affect the measurement values or make them unstable.
Degassing removes absorbed gasses from these elements
by heating the electron collector grid to 70 °C by electronic
bombardment. Degassing normally lasts 3 minutes but can be
aborted.
This function is available when the pressure is below 5x10-3
mbar (pressure recommended < 1x10-5 mbar). It is activated
when +24 V is applied to Pin 5 of the gauge.
DGS degassing

The crystal gauge must be adjusted to atmospheric (ATM) and
low pressure (VAC). If the hot cathode filament is ON and
pressure is below 1x10-4 mbar, VAC is adjusted automatically
every 5 minutes. When the filament is OFF (input DSBL activated)
and the gauge head is cold, manual adjustment is required. The
gauge automatically determines if it works at atmospheric or low
pressure. Before adjustment, the gauge must be mounted in the
same orientation and conditions it will be used in. It must be held
under these conditions for at least 10 minutes. To adjust zero, be
sur the gauge current pressure is below 1x10-4 mbar (7.6x10-5

The crystal gauge must be adjusted to atmospheric (ATM) and
low pressure (VAC). If the hot cathode filament is ON and
pressure is below 1x10-4 mbar, VAC is adjusted automatically
every 5 minutes. When the filament is OFF (input DSBL activated)
and the gauge head is cold, manual adjustment is required. The
gauge automatically determines if it works at atmospheric or low
pressure. Before adjustment, the gauge must be mounted in the
same orientation and conditions it will be used in. It must be held
under these conditions for at least 10 minutes. To adjust zero, be
sur the gauge current pressure is below 1x10-4 mbar (7.6x10-5

Parts on a vacuum processing system can be contaminated with
material that is detrimental to health and environment.
Before removing this gauge, confirm whether or not the gauge is
contaminated with any harmful gasses or vapors. If it is contaminated
with any harmful substances, be sure the gauge and equipment are
purged and cleaned thoroughly before removal of the gauge.
Take the necessary precautions when handling contaminated parts,
refer to 9 p. 13.
7- Gauge Removal
Outgassing from the electrode system of the hot cathode gauge
can affect the measurement values or make them unstable.
Degassing removes absorbed gasses from these elements
by heating the electron collector grid to 70 °C by electronic
bombardment. Degassing normally lasts 3 minutes but can be
aborted.
This function is available when the pressure is below 5x10-3
mbar (pressure recommended < 1x10-5 mbar). It is activated
when +24 V is applied to Pin 5 of the gauge.
