Operation
Pre-operation check procedure
Your spectrophotometer has been fully checked
and aligned before shipping. However, a short
pre-check should be performed before the first
use of this instrument.
1. Carefully unpack your spectrophotometer and
check every item against the Standard Equip-
ment list.
2. Place the spectrophotometer on a solid and
level surface in a dry, clean environment.
3. Confirm that the correct line voltage is set and
correct fuse is installed. 1.0A for 115V, or 0.5A
for 230V.
4. Plug the AC power cord into the rear of the unit
and plug into a grounded wall socket.
5. Turn the power ON by switching the rocker
switch at the rear of the spectrophotometer.
6. Allow the spectrophotometer to warm up for at
least 20 minutes to stabilize the electronic
components.
7. Set the wavelength dial to 340nm. Press the
100% T/0A button. The display should show
100.0 while in the TRANS (transmittance)
mode and 0.000 for the ABS (absorbance)
mode. Indicator lights below the main display
indicate whether the unit is in the transmittance
or in the absorbance mode. To change the
mode setting, press the T button for transmit-
tance or the A button for absorbance on the
front panel of the unit.
8. If the LED display shows Err3 or Err4, the lamp
alignment may have shifted during shipment.
