EPM-3D100MAB / 3 digit Mini Blue LED DC 100mA meter. Ideal for CO2 Laser power indicator(100mA)

Post by ddt154 »

Wired this up as instructed (Connection diagram: download/DSP/LaserMachineWiringDiagram2.jpg) and am apparently getting Error. No instructions came with unit. The P/N showing on box is QB8130A, Range: DC 100mA

Please see attachments..

Any help would be appreciated.
Regards,
Don
