RD700 | Digital Multimeter High Input Impedance

The Sanwa RD700 is a 4000 count digital multimeter with 0.3% accuracy. The RD700 is designed for low voltage circuits, home appliance measurements, and small communications equipment. This device comes in two variants, the RD701, and the RD700. The only difference between the two is that the RD700 does not include the AC True RMS feature for measuring AC sine waves. The RD700 comes with a 4000-count large format display and has an accuracy of 0.3%. It can be used to measure basic electrical parameters such as voltage, current, resistance, frequency, capacitance as well as temperature (300 ℃ max) using an optional K-type thermocouple sensor (K-250PC). The device features an ADP function for the current sensor, so that users can use the compatible current clamp sensor (CL-22AD & CL-22DC) to measure current in a conductor. This device has an auto-power off mode that turns the device off after 30 minutes (cancellable). It also features an alarm for wrong probe insertion in the current terminal. The meter has a fuse of 20 kA and has a protective holster with a wall hanger/lead holder and a tilting stand. Includes meter, rubber holster, instruction manual and one set of test leads. 4000 Count display with backlight 0.3% Accuracy Capacitance measurement K type temperature measurement Frequency measurement ADP function (for current sensor) Max recording measurement Range hold, Data hold, and Relative function Continuity confirmed by the buzzer Auto and Manual range selection Alarm for improper test lead insertion to current terminal Auto power off: Turns off after 30 minutes of no operation Protective holster with wall hanger and lead holder Tilt stand Specifications RD701 Measuring Range Accuracy Resolution Input Impedance DCV 400m/4/40/400/1000V ±(0.3%+4) 0.1mV 10M～1000MΩ ACV 400m/4/40/400/1000V ±(1.5%+5) 0.1mV DCA 400μ/4000μ/40m/400m/4/10A ±(1.2%+3) 0.1μA   ACA 400μ/4000μ/40m/400m/4/10A ±(1.5%+4) 0.1μA Resistance 400/4k/40k/400k/4M/40MΩ ±(0.6%+4) 0.1Ω Capacitance 500n/5μ/50μ/500μ/3000μF ±(2.5%+6) 0.1nF Temperature -20°C～300°C ±(2%+3) 1°C Frequency 50Hz～1MHz ±(0.5%+4) 0.01Hz Continuity Buzzer sounds at between 20Ω and 120Ω.
