4.2.8.10 Calibration unit – checkbox (optional)

The in-built Checkbox provides a simple and effective means of checking the calibration

of the SigmaGT instrument and accessories. According to the Code of Practice the

ongoing accuracy of the PAT tester should be verified at regular intervals and recorded.

This is of special importance if the PAT tester is used on a daily basis. The SigmaGT

includes an in-built calibration unit (‘Checkbox’) that is independent from the other

instrument’s electronic circuitry. During the calibration with the in-built Checkbox all

main instrument functions and accessories can be verified. The calibration results are

automatically stored into the instrument’s memory and can be viewed with the PATLink

PRO PC software.

Note:

 The Checkbox feature should be used to ensure that the meter is reading

correctly between calibrations but should not be regarded as a substitute for a

full manufacturers calibration on the unit.

The Checkbox starting screen is displayed first. In the REFERENCE column the

Checkbox reference values are displayed.
