The numbers climbed. 50mA... 100mA... 150mA...

B. Input Jacks (Three or four, depending on revision)

• COM (Black): Common ground for all measurements.
• V/Ω (Red): Used for voltage, resistance, diode, continuity, and currents under 200mA.
• 10A DC (Red): Used only for high DC current measurements. Never leave a lead here when doing voltage tests—you’ll blow the internal fuse instantly.
• ACA (Red – some models): Separate jack for AC current ranges.

: If the meter fails to measure current, check the internal fuses. Always disconnect the test leads and turn off power before opening the back cover. Internet Archive Manual Resources
