The level-meter board can be fitted in any expansion slot. Only one level meter board can be
fitted in a MercuryiTC, because of power consumption limitations.
1 Choose a slot for the level meter board.
2 Remove the two screws that secure the top clamping bracket (Figure 5). Remove the board
clamp.

3 Knock out the blanking plate (Figure 6) in the location where the board is to be fitted. The
blanking plates are held in place by 2 metal tongues (4 metal tongues on early iTCs).
• For the 2 tongue iTC, gently swivel the blanking plate back and forward until the retaining
tongues break.
• For the 4 tongue iTC, use a small chisel (or similar) and small hammer to break 2 of the
tongues with a firm tap. Then gently swivel the blanking plate backwards and forwards until
the remaining tongues break. Remove the blanking plate.
4 Remove the upper retaining screw holding the Helium probe 9 way D connector to the Level
