Measuring Resistance
• Seven Ranges: 100.000Ω, 1.00000 kΩ, 10.0000 kΩ, 100.000 kΩ, 1.00000 MΩ, 10.0000 MΩ, 100.000
MΩ
• Measurement Method: two-wire ohms
• Open-circuit voltage limited to < 5 V
• Input protection 1000 V on all ranges (HI terminal)
Measuring AC (RMS) or DC Current up to 1.2A
• Three AC Current or DC Current Ranges: 10.0000 mA, 100.000 mA, 1.00000 A
• Shunt Resistance: 0.1Ω to 10 Ω for 10mA to 1A ranges
• Input Protection: Front Panel 1.25A, 500V FH fuse for I terminal
