Time and frequency

Calibration 

Common measuring instruments that we calibrate:

• Time interval meters
• Frequency meters and generators
• Oscilloscopes
• Radio-frequency measuring instruments
• Tachometers
• Control instruments of tachographs (speed test, W parameter, time delay)
• Vehicle speed and distance meters (at the Tartu laboratory, devices with laser and radar working principle) 

Verification

• Vehicle speed meters (at the Tartu laboratory)
• Taximeters (at the Tartu laboratory) 

PS!  For the verification and/or adjustment or taximeters, please make an appointment at our Tartu customer service office.

Measurements

We provide measurements of time interval and rotation speed (e.g., centrifuges) along with the adaptation of taximeters (at the Tartu laboratory).

Traceability 

The traceability of time interval and frequency:

• Time interval and frequency measurements are traceable to the UTC timescale.
