19. Install the face plate onto the Display Interface Module. Install the two Phillips-head screws
that hold it in place.
20. Re-install the round green cover over the Display Interface Module. Rotate about 8-10 turns
clockwise, until almost snug. Red label should be in the “up” position.
21. Use a 1/16” Allen wrench to tighten the set screw on the cover to prevent removal or
unintended rotation.
7.3 AC Power Switch Settings
There are two switches that must be set for the supplied operating voltage. These are:
The first switch (Heater) is at
the center of the circle in the
diagram at right.
Switch position is as follows:
• UP: 115VAC
• DOWN: 230 VAC
The second switch is located on the
bottom of the optional air conditioner,
in a difficult location.
This photo shows the switch in the
115V position, using a round 45-
degree mirror to verify the setting.
Because this switch is rather
inaccessible, it is factory-set for the
voltage in the destination location. If
this switch needs to be reset due to
instrument relocation, please advise
Metrohm NIRSystems of this fact.
Instructions will be supplied for
changing the voltage.
