FEATURES • True RMS • Min/Max • 600A AC/DC • Peak hold • 750V AC/1000V DC • Visible high-voltage alert • Resistance 60MΩ • Manual ranging option • Capacitance 2000µF • Worklight/ back lit display • AC/DC microamps 2000µA • Low battery indicator • Frequency 99.
IMPORTANT SAFETY WARNINGS (CONT.) • Use caution when working with voltages above 60V DC or 25V AC RMS. Such voltages pose shock hazards. • To avoid false readings that can lead to electrical shock, replace batteries if a low battery indicator appears. • Unless measuring voltage or current, shut off and lockout power before measuring resistance or capacitance. • Always adhere to national and local safety codes.

OVERVIEW (CONT.) A. Clamp: Measure inductive AC/DC current. Opens to 1.25” (31.7mm). B. Conductor Alignment Marks: Use to aid the visual alignment of a conductor when measuring inductive amperage. Greatest accuracy is achieved when the conductor inside the clamp is centered at the intersection of these marks. C. Wire Separation Tab/ NCV sensor: Use to isolate an individual wire from a bundle for testing. NCV sensor detects live voltage. D. Test Lead Holder: Used for hands-free use of the test probes. E.
S. DC Zero/ Inrush Button: • Press to Zero the DC clamp reading. • Press and hold to enter LRA Inrush mode (must be in AC amp mode first). • Press and hold again to return to live readings. T. Display: • High contrast dual backlit display. • Amps (AC/DC) reading will always display on upper display. U. K-Type Temperature Probe Inputs: T1 (Upper) and T2 (Lower) V: Input Jack Lock: Switch to use Temperature or Test lead inputs W. Category Max Indicator: Maximum CAT Rating for input jacks.
