An aluminium baking tray was reworked to accept a couple of SO-239 sockets and the meter.
On completion of assembly and wiring, the unit had to be tested.
My homebrew CW rig's antenna current was set to 0.75A, using a Weston 1.5A RF Ammeter for measurement. The Weston was then replaced by the unit to be tested.
As luck would have it, the meter pointer stood at exactly 50% of full scale. Inspite of the non-linear output of the thermocouple and the uncalibrated meter scale, at least staying within the graduated portion of the scale would avoid damage to the element!
