Panel mount Volt/Watt transformer wiring

[compaddict]

I am wanting to add a Volt/Watt meter to my 220v coffee roaster. I'm mostly interested in the heater coil draw. I passed the two hots through the transformer and my display shows 0 watts when the heater is running. This is the meter: https://www.amazon.com/gp/product/B0928Z5SVT/?tag=atomicindus08-20
Please and thanks!

Did you separate the 2 wires as shown in that link?

You're just supposed to run 1 wire through the transducer.
Otherwise the currents will cancel out each other and show zero

Ahh! I was thinking that.
The load and Neutral messed my head up!
Thank you!

Better now! Shows amps but not KW? I can calc it easy enough though. Thanks!

Shows amps but not KW?

The transducer is used for multiple voltages. Watts depends on voltage.

by looking at the pictures,
The yellow digits are watts, assume that's a current reading.
the aqua digits are kwh, watts over time, 100 watts over 10 hours is 1000 watt hours or 1kwh.
it also says something about clicking the menu button to view the current and cumulative power consumption.

The transducer measure only amps. To get the voltage reading, you need an additional input.
The meter isn't completely hooked up.

I can read both volts and amps but not watts. I am getting volts from a different part of my circuit..

It may be time to contact the shenzhenshixinruidianzikejiyouxiangongsi customer service line.

Funny! I bought a second one to qualify the first.

Moral to the story: Quit buying cheap Chicom **** from Amazon.

if he hooked it up like the picture in post 2, the meter should be getting a voltage reading from the L-N input.

"I am getting volts from a different part of my circuit.."
220 (240) is a line-line voltage in the US

All better now!
Thanks for the support.

The meter isn't going to care if its 120 L-N or 240 L-L or 230 L-N in the UK.
Just like a DMM doesn't care if you're putting the leads on a 120 or 240 circuit.
