Getting Started
Performing voltage measurements
Ensure that the terminal connections are connected correctly before making any
C A U T I O N
measurement. To avoid damaging the multimeter, do not exceed the rated input limit.
AC voltage
• Five ranges: 500.00 mV, 5.00 V, 50.00 V, 500.00 V, 750.00 V
• Measurement method: AC coupled true RMS—measure the AC component with up to 400 VDC
• Crest factor: Maximum 3:0 at full scale
• Input impedance: 1 MΩ±2%parallel with capacitance <100 pF on all ranges
• Input protection: 750 V RMS on all ranges
