Designed primarily for HVAC professionals, the AM-520 autoranging digital multimeter offers all the most commonly used HVAC digital multimeter features such as temperature, micro amps to troubleshoot flame sensors, and capacitance to check motor startup capacitors. With its CAT III safety rating, this high voltage multimeter measures a broad range of electrical parameters. The backlit LCD display makes it easy to read, and it's easy to use with non-contact voltage detection, the “third hand probe holder, and the built-in flashlight.
The AM-520 comes with test leads, K-type thermocouple probe, one (1) 9 V (6F22) battery (installed), user's manual, velcro strap, and a carrying case.
• Measures AC/DC voltage up to 600 V, AC/DC current, resistance, frequency, capacitance and temperature
• CAT III 600 V safety rated
• Non-contact voltage detection enhances safety
• Audible continuity quickly identifies shorts and opens
• Diode test to verify polarity
• Data hold freezes the reading on the display for further analysis
• Min/Max recording records Min/Max measurements over time to show voltage fluctuations
• Relative zero mode displays the difference between the actual reading and a stored reference value and may be used with any function or range
• Combines user friendly features such as, auto power-off to conserve battery life, low battery warning, a “third hand test probe holder, built-in test leads storage, a built-in flashlight, and a Velcro strap to hang the meter
• Auto and manual-ranging delivers maximum flexibility
• Backlit LCD display with analog bar graph makes it easy to view results
