AstroAI Digital Multimeter, TRMS 4000 Counts Volt Meter Manual and Auto Ranging

The AstroAI True RMS Multimeter is designed to be safely and accurately used by professionals in a commercial setting or weekend DIYer's that need a little more power utility from their standard digital multimeter. It's easy and safe to operate with advanced features built for measuring seemingly everything. Run tests on diodes and transistors while being able to measure voltage, current, resistance, continuity, capacitance, and frequency, all on one device. This multimeter is designed to be used in commercial settings, but can also be brought home to use with automotive or household electrical problems.<br><br>Specifications<br>Digital Display: 3 ¾ , 3999<br>Sampling Speed: 2 times per second<br>LCD Size: 55 x 31mm<br>Range Selection: Auto or Manual<br><br>Polarity Indication<br>Overload Indication<br>Low Battery Indication<br><br>Operating Environment: 32°F~104°F (0°C~40°C); &lt;80% RH<br>Storage Temperature: 14°F~122°F (-10°C~50°C); &lt;85% RH<br>Power: 3 x 1.5V, AAA Batteries Included<br>Dimensions: 145x70x35mm<br>Weight: Approx 157g<br><br>Safety/Compliances: EN 61010-1 CAT III 600V<br>DC Voltage: 400mV ±(0.8%+3), 4V/40V/400V ±(0.8%+3), 600V (1%+5)<br>AC Voltage: 400mV ±(1.2%+5); 4V/40V/400V ±(1.0%+8); 600V ±(1.2%+5)<br>Temperature: -40°C~1370°C; -40°F~2000°F (2.5%+4 depending on temp)<br>DC Current: 400?A/4000?A/40mA/400mA ±(1.2%+8); 4A/10A ±(1.2%+8)<br>AC Current: 400?A/4000?A/40mA/400mA ±(1.5%+8); 4A/10A ±(2.0%+10)<br>Transistor hFE: PNP &amp; NPN (lb?2?A; Vce?1V)<br>Resistance: 400?/4K?/40K?/400K?/4M? ±(1.5%+3); 40M? ±(1.5%+3)<br>Capacitance: 40nF±(8%+10); 400nF/4?F/40?F/400?F/40mF/100uF~2mF±(5%+5)<br>Frequency: 5/50/500/5K/50K/500K/5MHz ±(1%+3)<br><br>Package Contents:<br>1 x AstroAI 4000 Counts Digital Multimeter<br>1 x Test Leads (Pair)<br>1 x K-Type Thermocouple<br>1 x User Manual<br>
