Home-made TEST UNIT for the
WESTON PORTABLE WATT METER
A T E S T - U N I T for the WESTON PORTABLE W A T T - M E T E R
************************************************************************
Instead "Flying Wires Experiments" when demonstrating this beautiful
Watt-Meter, I decided to build also a US-Version of a TEST-UNIT. Typical
APPLICATION: How much (not longer readable) "WATT" has this older light
bulb ? ... Answer: " 40 WATT !"

The WIRE DIAGRAM of the » WATT-METER TESTER-2 « shows 2 FIXTURES for
light bulbs ( L1 & L2, with an insert for small bulbs ), a DUAL-POWER-
PLUG ( P1 & P2 ) to test eg. Heaters or Fans and 3 EXTENSION-PLUGS to
test "Other Devices". The GLOW-LAMP on the left indicates that power
is connected. The SWITCH has its "OFF" position in the middle. It allows
to power the object (= "TEST") before the ( colored ) measurement cables
from the Watt-Meter are plugged in. In position "WATT" the Watt-Meter is
in the loop.
