Changing the Weighbridge Battery

Figure 38 The Weighbridge for the Automated ATR Objective
The weighbridge supplied with the automated ATR objective allows you to apply a known
and repeatable force to the sample when you are collecting spectra. This relies on the
weighbridge communicating with the microscope using a wireless infrared transmitter
powered by a battery. When the battery power starts to decrease, Spectrum displays a
symbol in the Status bar at the bottom of the screen. You should change the battery at this
point. If the symbol changes to , the weighbridge will not function until the battery is
replaced.
To change the weighbridge battery:
1. Remove the four screws from the corners of the weighbridge and lift it off the
microscope stage.
2. Turn the weighbridge over and place it on a clean, flat surface.
3. Loosen the three captive screws in the cover on the underside (Figure 39).
