Electrician's HVAC Contractor TRMS Multimeter Description The Ames True-RMS digital multimeter has a full menu of features. Use this professional multimeter to measure and verify the presence of voltage before connecting new equipment or performing repairs. The LoZ feature helps detect the presence of "ghost voltage" when installing cable or tracing faults on cable runs. Its µA and temperature measurement features are designed for HVAC applications, testing flame sensors, and making temperature measurements. This meter is fully safety rated to CAT III 1000 V providing an extra measure of safety for high voltage applications and has been independently tested by ETL. AC and DC voltage Measurements up to 1000V Resistance range: 66MΩ AC/DC Current: 10A Build in non-contact voltage measurement Auto-Hold captures the first stable displayed value Display: 6000 Counts, True RMS Audible Continuity, Data Hold, Low Battery Indicator LoZ low input impedance: helps prevent false readings due to ghost voltage Auto ranging, diode test, bright display / back light, and auto power off Specifications Name Electrician's HVAC Contractor TRMS Multimeter SKU 64019 Brand Ames Accuracy DC Voltage: +-(0.8%+3)AC Voltage: +-(1.0%+3) DC Current: +-(2.0%+5) AC Current: +-(3.0%+5) Resistance: +-(1.5%+5)Temperature: +-(1.0%+3) Capacitance: +-(4.0%+5) Frequency V Position: +-(1.5%+5) Frequency Hz Position: +-(1.5%+5) Duty Cycle: +-2% Battery type Alkaline Battery(s) Included (y/n) Yes Battery(s) required one 9V Duty cycle 1%~99% Frequency (Hz) 66Hz/660Hz/6.6Hz/10kHz (V position), 66Hz/660Hz/6.6Hz/66kHz/660kHz/6.6MHz/66MHz (Hz position) Temperature range (deg F) 0° C~1000° C/ -32° F~1832° F Product Height 52 mm Product Length 175 mm Product Weight 420g Product Width 85 mm Shipping Weight 1.40 lb.
