• 4-1/2 digit mode for precise measurements (20 000 counts)

• True-rms ac voltage and current for accurate measurement on nonlinear signals

• Measures up to 1000 V and 10A AC and DC (note that Ex zones require reduced measurements)

• Low pass filter ensures accurate voltage and frequency measurements on variable speed motor drives (VSDs)

• Frequency to 200 kHz and % duty cycle to help you diagnose VSDs and switching power supplies

• Resistance, continuity and diode test

• 10 000 μF capacitance range for components and motor caps

• Conductance measurements for high resistance or leakage tests

• Min/Max-Average and Peak capture to record transients and variations automatically

• Relative mode to remove test lead interference on resistance measurements

• Auto and manual ranging for maximum flexibility

• Input Alert protects you by chirping and flashing “Lead when leads are plugged into the wrong inputs
