(B) PRE-INSTALLATION CHECKOUT
1. Extreme care should be taken when unpacking and handling the Reference Standard or sample cu-
vettes as surface scratches or finger smudges will cause measurement errors. Handle these items by
the top only. (See Fig. 1)
(C) INSTALLATION AND START-UP
1. The instrument is factory set for 120 volt operation. If 240 volt operation is desired, set the switch on
the back of the instrument to “240”, change fuse to ½A quick acting and provide appropriate power
cord.
2. The Range Selector switch located on the front of the instrument should be in the 1000 range position.
3. Leave the Light Shield cap in place on the instrument when it is not in use in order to protect the
sample well from dust, etc.
4. For best operation it is recommended that the instrument be left on continuously.
NOTE: A 240V fuse is provided in accessory kit.
