TSI Instruments SMPS 3938 - Installing Lead Shielding

2-6 Electrostatic Classifier Model 3082 and SMPS Spectrometer Model 3938
Notes: When plugged in, the unit powers on automatically.
Detailed instructions for all these steps are given on the
following pages.
Installing Lead Shielding
A lead radiation shielding (optional accessory) may be installed inside the
Electrostatic Classifier Model 3082. This shielding is at least 10 mm thick
and will reduce the radiation level to <1 µSv/hr at a distance of 10 cm from
any touchable surface of the classifier. In some countries or localities, the
Model 3077A neutralizer must be operated with lead shielding installed.
To install the lead shielding, follow these instructions:
1. The classifier cover is attached with eight (8) screws. Using a Phillips-
head screwdriver, loosen the bottom two and top three screws.
Remove the other screws and save for reuse.
Note: Do not remove any of the captive nylon washers from the
screws.
