Figure 35 - Calibration gas cap connection
The instrument is supplied with a calibration cap and tube.
1.
Push one end of the tube onto the calibration cap and connect the other end
onto a suitable supply of calibration gas. Calibration gas cylinders are available
from Servomex. For the latest ordering options please contact your local
Servomex agent or visit
2.
Firmly push the calibration cap onto the front nozzle of the instrument. You
cannot push the cap too far onto the instrument and you should feel the cap
push on and locate on the o-ring grove. It should be firmly in place after fitting.
3.
To remove the calibration cap, grip firmly around the knurled bezel and twist and
pull gently until it is removed. Do not remove the cap by pulling on the tube.
The calibration cap may be stiff and slightly difficult to remove when first
fitted. This is normal and will ease with use.
You must switch on the electrical supply and leave the instrument for at least
1 hour to stabilise before you calibrate the instrument.
