• Ranging:  Manual or autoranging
• Autoranging Time:  Average 250 msper range change
• Settling Time at Display: 
• Conversion Period:  300ms
• Temperature Coefficient:  (0°–18°C & 28°–50°C): ±(0.1 × applicable accuracy specification)/°C
• Maximum Common Mode Voltage:  30V rms, DC to 60Hz sine wave
• Analog Output:
  • Output Voltage:  +1V = –10000 counts, except +100mV = –10000 counts on 2nA range
  • Output Resistance:  1kΩ
• REL:
  • Pushbutton allows zeroing of on-range readings
  • Allows relative readings to be made with respect to baseline value
  • Front panel annunciator indicates REL mode
• Data Store and Min/Max:
  • 100 reading storage capacity
  • Records data at one of six selectable rates from 3 readings/second to 1 reading/hour, or by manual triggering
  • Also detects and stores maximum and minimum readings continuously while in the DATA STORE mode
• Log:
  • Displays logarithm (base 10) of the absolute value of the measured current
  • (examples: –3.000 = ±1mA; –6.301 = ±0.5μA)
