Installation
1. Place the spectrophotometer on a solid and level surface in a dry, clean
environment.
2. Leave an open space at least 50mm distance from rear panel and side walls
to guarantee air flow around the instrument.
3. Connect the female end of power cord into the inlet of AC adapter, and then
the outlet plug of AC adapter into the DC input hole on the rear panel of
instrument.
4. Plug the power cord into a grounded wall outlet with the appropriate
voltage.
5. Connect the Centronics parallel printer to the instrument at the print port.
6. Turn on the power switch and allow instrument to warm up at least 30
minutes for electronic and thermal stabilization.
7. The standard cell holder is adaptable for 10 mm square cuvette and 1/2”
round tube. For 50 mm long-path cell measurement, please unscrewing
two white knobs (#1) and removing metal bracket #2 inside the sample
compartment as shown in figure 4a, then locate bracket #3 and tighten two
knobs again(figure 4b).
8. For 1” round tube measurement, orient bracket #4 and tighten two knobs
(figure 4c).
