GAUGE PARTS AND ACCESSORIES
Figure 1–1 shows the Model 4640-B gauge and its accessories. Use
this figure and the list below to identify the gauge and parts as they
are unpacked.
1. The Gauge is the portable instrument containing all electronic
modules, rechargeable battery packs, detectors, and the
radioactive source.
2. The Air Gap Spacer is used whenever a reference standard
count is taken. The spacer ensures that underlying material does
not influence the reference standard count.
3. The (Magnesium) Reference Block provides a uniform
reference material for gauge adjustment due to such factors as
source decay.
4. The Charger/Adapter provides a means to recharge the gauge
batteries. The charger/adapter for domestic use operates on
120 V ac/60 Hz; the charger/adapter available for use outside
the U.S. operates on 120/230 V ac (50/60 Hz). Also included is
a 12 V dc charger.
5. The Transport Case is a DOT-approved shipping container
that may be used for shipping the gauge and accessories.
6. The optional Serial Printer connects to the gauge for printing
data.
7. The optional Serial Interface Cable (not shown) may be used
to connect the gauge to a printer or computer.
