Selecting current input terminals and measurement range
If AC or DC current is being measured in auto- ranging
mode, with a signal input at 100 mA, the meter will select
the range 100 µA to 100 mA automatically.
If a signal input is applied to the 10 A input terminal, the
meter will select the 1 A to 10 A range automatically.
Measuring AC (RMS) or DC voltage
AC Voltage:
• Measurement Range: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V, 750.00 V
• Speed: Slow-2 Hz, Medium-20 Hz, Fast-200 Hz
•Default Setting: Autoranging, Slow measurement speed
• Measurement Method: AC coupled true RMS - measures the AC component
with up to 400 VDC bias on any range
• Crest Factor: Maximum 3:1 at full scale
• Input Impedance: 1 MΩ ± 2% in parallel with <100 pF on all ranges
• Input Protection: 750 V rms on all ranges (HI terminal)
DC Voltage:
• Measurement Range: 100.000 mV, 1.00000 V, 10.0000 V, 100.000 V, 1000.00 V
• Speed: Slow, Medium, Fast
•Default Setting: Autoranging, Slow measurement speed
• Measurement Method: Sigma Delta A-to-D converter
• Input Impedance: >10 GΩ selected range (0.1 V and 1 V only) or ~10 MΩ all
ranges (typical)
• Input Protection: 1000 V on all ranges
(HI terminal)
