Atec King-Nutronics-3112 - Manual (Page 2)

A 65 to 250 VAC electrical tester is built into the Model 3112 Portable Live Pressure Calibration and Test
System for convenient pneumatic switch testing. The electrical tester is connected from the front panel of the
test system to the switch being tested using two 5-foot leads terminated with alligator clips. The presence of
electrical current is shown using a neon lamp. The lamp will illuminate to indicate that voltage is present;
when applied pressure trips the switch, the lamp will turn off.
All components of the Model 3112 Portable Live Pressure Calibration and Test System, including the test
hose, technical manuals, and other supplies, are housed in a weatherproof, compact, and rugged aluminum
carrying case with a locking hinged lid. A pressure relief valve built into the storage case protects the system
from internal gas leakage during storage.
