10 Disconnect the in-vacuum cable from the feedthrough.
11 At the feedthrough, measure resistance between the center contacts of the
BNC and coaxial connectors (shown by
Figure 5-6 ).
Figure 5-6 Feedthrough Resistance
 If resistance is more than 0.3 Ω, contact INFICON (refer to section 1.3, How
to Contact INFICON, on page 1-2 ).
 If resistance is less than 0.3 Ω, continue to step 12.
12 Replace the in-vacuum cable.
13 Reinstall the crystal holder with ceramic retainer and without the crystal into
the sensor.
14 Measure resistance between center contact and shield of BNC.
 If resistance is less than 1 Ω, electrical continuity is good.
 If resistance is more than 1 Ω, contact INFICON.
