Joranalogue Test 3

V/mA meter for testing module current draw and rail voltages

8 HP Eurorack module

Test 3 is an 8 HP Eurorack V/mA meter that replaces a bench full of multimeters and custom cables. Connect a module (or a flying busboard of modules) to its Meter Output power header and the four-digit display shows voltage, real-time current, or stored peak current for each of the three rails (+5, +12, -12). Two buttons cycle the selected rail and measurement mode; peak current is tracked continuously on all rails in the background. It measures up to 20 V and 1 A per rail with 20 mV / 1 mA resolution.

Features

  • Measures V, mA and peak mA on +5, +12 and -12 rails
  • 20 mV voltage resolution, 1 mA current resolution
  • Up to 20 V and 1 A measurable per rail
  • Continuous background peak-current capture on all rails (100 Hz)
  • Four-digit LED display blinks on overload
  • Hold Mode to reset stored peak values
  • Meter Output header measures one module or a whole busboard
  • Excludes its own +12 V draw from the +12 reading
  • Reverse-polarity MOSFET power protection
  • Available as an easy DIY kit; 8 HP module version
  • Made in Belgium
