Digital multimeter jacks

 

 
1 A (amps)
Red test lead input for:
  • Current measurements of up to 10.00 amps.
  • Current measurements of frequency and duty cycle.
  • Optional mA output current clamp for current measurements of 400 A or more, up to the limit of the clamp.
2 mA, µA (milliamps, microamps)
Red test lead input for:
  • Current measurements of 0 microamps (µA) to 400 milliamps (mA; up to 600 mA for 18 hours).
  • Current measurements of frequency and duty cycle.
  • Optional mA output current clamp for measurements of up to 600 amps ac.
3 COM
Black test lead input for:
  • All measurements.
  • Low/negative connection for circuit measurements or accessories.
  • Alternately known as “return terminal.” COM is short for common.
4 Voltage (V), resistance (Ω), diode test ( diode test ), capacitance ( Capacitance symbol ), temperature.
Red test lead input for:
  • Measurements for voltage, resistance, diode, capacitance, frequency, duty cycle and, if available, temperature.
  • Also accepts red clamp lead when using Hall Effect-style current clamps.
Notes:
  • Important: The input jack chosen for the red test lead MUST match the parameter selected on the dial. Dial set on ac volts? Make certain the red test lead is plugged into the jack designated for voltage and not current. If not, the meter, equipment, and technician are all at risk.
  • Not all meters offer an input jack for milliamps (mA) and microamps (µA).
