Page 3: Specifications
Always discharge capacitors and remove power from the device under test before performing Capacitance, Diode, Resistance or Continuity tests. Remove the battery from the meter if the meter is to be stored for long periods. To avoid electric shock, do not measure AC current on any circuit whose voltage exceeds 250V AC. - Page 4 Function Range Resolution Accuracy AC Current ±(1.8% reading + 5 digits) 400µA 0.1µA (A AC) 4000µA 1µA (40 - 400Hz) 40mA 0.01mA (40 - 200Hz for 400mA 0.1mA 400µA, 4mA ±(3.0% reading + 7 digits) 0.01A ranges) ±(1.2% reading + 4 digits) Resistance 400Ω...
