You are looking at one of the COOLEST add ons Lionel has produced.
This is an add-on meter to measure the voltage and amperage output on your older postwar ZW. THIS ONE is specifically for the OLDER pre-1969 ZW transformers. It can measure output on each of the four outputs from the transformer.
The Amp/Volt Meter for ZW controllers allows you to monitor the output of all four ZW channels with a digital LED display. Give each channel the exact power you want by watching the readings increase or decrease as you move your ZW handles. Simple to install, the Amp/Volt meter fits conveniently on the top of your ZW controller for easy monitoring.
CONDITION: C-10 brand new in the box. Meter unit is still sealed. With paperwork, instructions, etc.
