FAQS

Portable Calibration Table – Your Precision Calibration Solution

What is it?
A vertical single-step displacement tool designed for precise sensor calibration.

Why is it useful?
Equipped with a dial gauge featuring micrometer precision, this tool provides exact displacement measurements—a critical factor for generating accurate instrument response files or validating existing ones.

How does it work?
To ensure robustness and field-readiness, we’ve eliminated all motorized components. Instead, the calibration table operates with a manual lever:

No gearboxes
No fuss
No external power supply needed

Simple. Reliable. Efficient.

Is it portable?
Absolutely! The Portable Calibration Table is built for field operations and remote locations, offering unmatched flexibility outside traditional laboratory settings.

Will it work with my sensor?
Yes! It’s compatible with:

You name the sensor—this calibration table can handle it.

Does it come with an extension bridge for horizontal components?
Absolutely. The extension bridge ensures precise calibration for horizontal components, enhancing the versatility of your setup.

Is it complicated to use?
Not at all! While the engineering design ensures true vertical motion (a challenging task), your job remains effortlessly simple—just move the lever.

Can I build my own?
Sure! You can refer to Erhard Wielandt’s plywood calibration table design instructions. However, when commercial-grade precision and durability are required, our Portable Calibration Table is your best choice.

Can I send my instruments to QuakeLogic for calibration?
Absolutely! We’ll provide a new, up-to-date response file for your instrumentation, including:

Poles and zeros
Gain
Full transfer function

Delivered in RESP, dataless, or inventory-XML formats—compatible with Earlybird, Earthworm, ObSpy, Seisan, and SeisComP.
