If space does not permit leaving the blue Guard attached to the cable connection during
installation, separate the Guard from the cable connector, and install as follows:
■
Grasp the Guard with your fingers.
■
Place your thumb on the blue connector between two of the tabs on the connector end of
the Guard.
■
Carefully insert a small flat screwdriver blade under the tab and gently pry outward on
one tab and then the other while forcing the blue connector sideways.
■
The connector will pop out of the Guard. Use care not to permanently deform the tabs.
■
Place the Guard on the Gauge.
■
Complete steps 5-a through 5-f (rotate the connector instead of the Guard in step “f”).
■
Push the Guard back on the connector.
To remove the connector from the Stabil-Ion Gauge, rotate the blue Guard counterclockwise about
20° until it hits the stop. Pull the connector straight back from the gauge.
Clamp the gauge cables in a fixed position throughout their length to provide strain relief at the
connectors and to prevent undesirable effects on performance that might be caused by cable
movement.
Do not touch the Stabil-Ion Gauge during degas operation if the Guard has
been removed. Serious burns can occur.
Danger, high voltage – 180V is present in the Power Supply, on the cable,
and at the ion gauge when the gauge is turned ON. Voltages as high as
850V peak are present during degas.
Do not operate in an explosive atmosphere.
Do not operate the product in the presence of flammable gases or fumes.
Operation of any electrical instrument in such an environment constitutes a
definite safety hazard.
Do not use the product to measure the pressure of explosive or combustible
gases or gas mixtures. Ionization gauge cathodes operate at high
temperatures. The sensor wire of the Convectron Gauge normally operates
at only 125°C, but it is possible that Control Unit malfunction can raise the
sensor temperature above the ignition temperature of combustible mixtures.
Danger of explosion or inadvertent venting to atmosphere exists on all
vacuum systems which incorporate gas sources or involve processes capable
of pressurizing the system above safe limits.
Operation of the product with line voltage other than that selected by the
proper power supply switches can cause damage to the instrument and
injury to personnel.
