AEMC AC Current Probe Model LM102 The LM102 is a general-purpose AC current probe designed for Power analyzer, DMM and other measuring instruments with current input. It has a 1000:1 ratio and an output of 1mA per Amp. The LM102 has integral 5 ft (1.5m) leads terminated by safety 4mm banana plugs. The LM102 has protective diodes across the output that limit the voltage in open secondary situations Maximum Conductor Size .63" (16mm) Current Range 200Arms AC Measurement Range 0.05 to 350A Output Signal 1mA/A AC (200mA @ 200A) Transformation Ratio 1000:1 Output 5 ft (1.5m) lead with 4mm safety banana plug Accuracy 50/60Hz 1.5% ± 0.02A Frequency Range 48Hz to 10kHz Phase Shift at 50Hz 3° max Open Secondary Voltage
