7.4 Calibration Equipment

The diagram below displays the regulator and tubing equipment for user calibration:



Certified calibration gas in 58 litre gas canisters is supplied with the Geotech

calibration kit. Please refer to the Geotech website

www.geotech.co.uk

for further

information.



The regulator supplied with the calibration kit is recommended as flow and pressure

rates are factory set.



Note: Maximum input pressure 250mb, maximum flow 300ml.

7.5 Calibration Method

Before you begin ensure the unit is stabilised at its working temperature before performing

any of the calibration operations.

To achieve the processes set out in this section, press ‘Key 3 – Calibration’ from the ‘Main’

menu. The first screen displayed provides the option to select the gas that requires

calibration.

Calibration

The exact calibration method can vary depending on the gases used.
