• ±0.5% DC V basic accuracy, wide 40 Hz to 1 kHz AC V frequency characteristics
• Low-pass filter cuts high harmonics (when measuring inverter fundamental waveforms)
• Broad -10 (14°F) to 65°C (149°F) operating temperature range
• Display backlight

Introduction of voltage input protection functionality

This functionality keeps errors in instrument configuration from resulting in an electrical accident. Even if the instrument’s rotary switch is mistakenly set to the resistance
function when attempting to measure voltage, placing the probes in contact with the circuit under measurement will not cause a tripped circuit breaker or electrical arcing..
