Further discussion and picture here on my forum: http://mjlorton.com/forum/index.php?t... I part 1 of this review I take a look at the features, functionality, resolution and accuracy of the UT71D. In some respects I compare it to the Agilent U1272A. I use both the PentaRef and DMMCheck Plus from Doug at VoltageStandard.com Details and specs of the UNI-T (Unitrend) UT71D: http://www.uni-trend.com/UT71d.html Basic Functions Range Best Accuracy DC Voltage 400mV/4V/40V/400V/1000V (0.025%+5) AC Voltage 4V/40V/400V/1000V (0.4%+30) AC Bandwidth 100KHz DC Current 400µA/4000µA/40A/400mA/10A (0.08%+8) AC Current 400µA/4000µA/40A/400mA/10A (0.5%+15) Resistance 400W/4kW/40kW/400kW/4MW/40MW (0.3%+8) Capacitance 40nF/400nF/4µF/40µF/400µF/4mF/40mF (1%+20) Temperature (°C) -40°C ~ 1000°C (1%+30) Temperature (°F) -40°F ~ 1832°F (1.5%+50) Frequency 40Hz/400Hz/4kHz/40kHz/400kHz/4MHz/40MHz/400MHz (0.01%+8) Duty Cycle 10%~90% (1%+30) 4~20mA Loop 0~100% (1%+50) Power Measurement Special Functions Fused 10A Range Auto Ranging Current Measurement Alarm Function Set Up Auto Ranging Votage & Current : AC + DC Measurement Data Logging 9999 Data Recall Diode Continuity Buzzer True RMS Peak Hold Max/Min Mode Relative Mode Data Hold USB Double Display Backlight Full Icon Display Sleep Mode Low Battery Display Input Impedance for DC Voltage Measurement DC 200mV : Around 2.5GW All Other Ranges : 10MW Max.
