Installation of the Vial Heater Module
1. Place the Vial Heater Module near the
instrument so that the transmission
probes will reach the heater block.
The photo shows a typical finished
installation.
Do not plug the Vial Heater Module
in to AC power at this time.
2. Insert transmission probes into holes on
the left and right side of the Vial Heater
Module. Press firmly until both probes
bottom in the heater block.
Do not kink or bend the fiber optic
bundles. The minimum bend radius is 15
cm, or 6 inches. Do not rest heavy
objects on the fibers, as they can be
crushed or damaged.
3. Secure in place with setscrews located in
top of heater block. The setscrews
require a 5/64” ball driver.
(A complete set of balldrivers is included
with the monochromator accessory kit.)
See photo, showing tightening of left
side setscrew.
