By removing the M3 screw locking the crystal gauge M-332MX gauge head as shown in
the above figure, the gauge head can be pulled away and detached.
When pulling away the gauge head, be certain to pull it straight. If stress
is applied to the pins of the gauge head, there is a risk of a leak
occurring at the gauge head pins.

Attaching the Gauge Head
Gauge head insertion guide
Check the M3 gauge head locking screw is loose and the gauge head pins are all standing
perpendicular. Align the gauge head insertion guides on the gauge head side and the
controller side and then insert the gauge straight.
After inserting, tighten the M3 gauge head locking screw to lock the gauge head securely to
the controller. If the gauge head is not inserted cleanly into the controller, do not force it.
Re-check the M3 screw and gauge head pins and then try again.
When inserting the gauge head, be certain to insert it straight. If stress
is applied to the pins of the gauge head, there is a risk of a leak
occurring at the gauge head pins. Also, if it is forcibly inserted, the
gauge head and the controller may be damaged.
