# Extech MM560A MultiMaster Precision Multimeter (Pre-Owned) # Extech MM560A MultiMaster Precision Multimeter (Pre-Owned) ## Key Features At A Glance - CAT IV-600V safety rating with double injection-molded test leads on all models - Basic DC voltage accuracy from 0.02% to 0.03% across the series - 50,000 count display (500,000 for DCV and Hz), backlit LCD with bargraph - True RMS AC+DC combination function for rectified, non-symmetrical waveforms - AC/DC current to 10A with 0.01µA resolution - 4 to 20mA displayed as 0-100% for process current measurements - dBm measurements with 20 selectable impedances; resolution to 1µV, 0.0001Hz, 0.01Ω, 0.1° - Optional Windows PC software and optically isolated cable for data collection The Extech MultiMaster Series comprises the MM560A and MM570A precision multimeters, true-RMS handheld instruments built around a 50,000 count backlit LCD display (500,000 count for DC voltage and frequency) with an analog bargraph. Both models carry a CAT IV-600V safety rating and use double injection-molded test leads, and the MM570A extends the platform with integrated temperature measurement. The series includes a filtered frequency function with adjustable trigger levels intended for variable speed motor drives and high voltage applications. A 4 to 20mA mode displays current as 0 to 100% for process current measurements, and a special True RMS AC+DC combination function measures rectified, non-symmetrical voltage and current waveforms. The MM570A adds Type K thermocouple temperature measurement. ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, and has supplied test and measurement equipment to engineers and labs since 1992. Every used unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received. ## Compare Other Models in This Series The MultiMaster Series is offered as two models, the MM560A and the MM570A precision multimeters, with the MM570A adding temperature measurement. Both share the 50,000/500,000 count backlit display, True RMS AC+DC measurement, CAT IV-600V rated leads, and the full function set of voltage, current, resistance, capacitance, frequency, continuity, duty cycle, and diode test. Both models are also listed in factory calibration-traceable versions in the ordering information. The MM570A is further distinguished by higher basic accuracy, wider True RMS bandwidth, and dual Type K temperature inputs. Each pre-owned model below is its own dedicated product page with condition-matched pricing. Select the MM560A or MM570A page that fits your application and budget to see the specifications and price for that pre-owned configuration. The MM560A provides 0.03% basic DC voltage accuracy, True RMS AC voltage bandwidth up to 20kHz, and 600V input protection on all functions (1000V on Voltage). The two models differ across several headline specifications. The MM560A delivers 0.03% basic DC voltage accuracy with True RMS AC voltage bandwidth up to 20kHz and 600V input protection on all functions (1000V on voltage). The MM570A delivers 0.02% basic DC voltage accuracy, True RMS AC voltage bandwidth up to 100kHz, and 1000V input protection on all functions. Temperature measurement is a key differentiator: the MM570A adds T1, T2, and T1-T2 dual Type K input temperature display in °F or °C, a function the MM560A does not include. The comparison table below details the per-model ranges, resolution, and accuracy.
