M-012 Bipolar voltmeter with invertor

3 switchable ranges (front panel switch): -2 to +2V, -4 to +4V, -8 to +8V, zero in the middle.
4 steps for positive and 4 steps for negative voltage in selected range.
One normal output (parallel), one output inverted.

Very handy for checking CV or audio levels between modules.
For example:
slow LFO will light up alternating bar up and down (depends of waveshape),
symmetric VCO output will light symmetric bars (alternating too fast for eye) which appears like

Continuous light in positive and negative range.

Not suitable for exact measuring of CV (tuning check or so). Step spacing is too big for this.
Quality components, laser-marked panel.
Silver coated PCB.

Width: 4TE/ 4HP/ 20mm.
Depth: 60mm /2,4"
Current: 6mA
