HMP45C Temperature and RH Probe

5. Continue to carefully insert the probe a further 10mm, until the shoulder of

the larger section is approximately level with the hole in the lowest curved

disc, as shown in Figure 2 (b), below.

6. Tighten the large retaining nut by hand (do not use any tools) until the probe

is firmly gripped. If the probe does not appear to be sitting squarely inside

the shield, loosen the nut, re-position the probe and re-tighten. DO NOT

PULL THE PROBE DOWNWARDS PRIOR TO TIGHTENING THE

NUT, as this will also pull the sealing membrane downwards producing a

water trap. (See CAUTION below.)

7. Finally, bend the cable in a gentle loop back up towards the mounting arm

and attach it to the arm with the cable ties supplied.
