Hb 145 was developed as a source of calibration procedures for weights and. Page 30 evaluate accuracy of the horizontal time scale comb or triangle waveforms are usually used with analog oscilloscopes oscilloscope calibration techniques. An oscilloscope is an incredibly useful tool to have on your electronics workbench. Manual calibration methods are well established, and for analog oscilloscopes there is possibly no costeffective alternative, although techniques are being developed which employ oscilloscope calibrators together with memorized calibration procedures directed at individual oscilloscope models. There is a bubblelevel just behind the digital readout.

In measurement technology and metrology, calibration is the comparison of measurement. Unfortunately, oscilloscopes are also expensive, costing at least a few hundred dollars. The procedure described in this paper can be easily adapted to calibrate other optical instruments e. Hb 145 was developed as a source of calibration procedures for weights and measures laboratories and covered mass, length and volume calibrations for field standards used in the commercial marketplace. Before calibration or adjustment, warm the reference oil to approximately 50 c in hot water.
