Why are there spikes on the vertical channel of my Nanometrics Accessories?
Spikes on the vertical channel are usually due to electrical system noise. Check for power supply noise from a battery charging circuit or interference from a strong magnetic or radio source that is nearby.
How to fix large mass positions and velocity output offset in Nanometrics Accessories?
If the mass positions are large, but slowly trending towards zero and one or more of the main velocity outputs has an offset on the order of several volts, here are a few possible solutions: * If the Trillium Compact was powered and not level or was powered during leveling, leave the sensor un-powered until after it is level. * Power cycle the unit; this momentarily puts the unit in short-period mode during start up. * Access the user interface, put the unit into short-period mode, and then immediately return it to long-period mode. * Use the control lines on the digitizer to briefly put the unit into short-period mode, and then return it to long-period mode.
Why is there continuous low frequency wander in my Nanometrics Accessories?
Continuous low frequency wander, which manifests as random noise and is more pronounced on horizontal channels, may be caused by air drafts due to an unsealed hole, leading to temperature fluctuations. It is suggested to visit the site to seal the hole.
What to do if mass positions are large and trending towards zero in Nanometrics Industrial Equipment?
If the mass positions are large, but slowly trending towards zero, and one or more of the main velocity outputs has an offset on the order of several volts, it could be because the Trillium Compact is powered and not level. For fast recovery after leveling: Leave the sensor unpowered until after it is level; Power cycle the unit to put it in short-period mode during start up; Access the user interface to put the unit into short-period mode, and then return it to long-period mode; Use the control lines on the digitizer to briefly put the unit into short-period mode, and then return it to long-period mode.
