Product Overview
The Sanwa RD700 is a compact digital multimeter developed by Japan s Sanwa Electric Instrument. Featuring a large LCD display and impact-resistant synthetic rubber casing, this handheld device is ideal for industrial electrical applications. It provides comprehensive measurement capabilities including AC/DC voltage, AC/DC current, resistance, capacitance, frequency, diode test and temperature measurement (with optional K-type thermocouple). The meter boasts high input impedance of 1000MΩ and 3-3/4 digit 4000-count display with basic accuracy of 0.3%. 1619
Key Features
This multimeter incorporates several practical functions such as relative measurement mode to eliminate test lead resistance, warning alarm for incorrect current terminal insertion, and built-in thermometer function (-20°C to 300°C range with optional probe). The ADP function allows current measurement up to 3000A when used with optional clamp adapters. Gold-plated test leads are included to ensure reliable contact. An auto power-off function (30 minutes, can be disabled) helps conserve battery life. The tilt stand design facilitates hands-free operation during measurements. 41419
Measurement Specifications
Voltage ranges cover 400mV to 1000V for both DC and AC measurements. Current measurement spans from 400μA to 10A. Resistance ranges from 400Ω to 40MΩ, while capacitance measurement covers 500nF to 3000μF (excluding leaky capacitors). Frequency measurement supports 50Hz to 1MHz for sinusoidal or 40%-70% duty cycle square waves. The unit meets safety standards for CAT III 600V and CAT II 1000V applications. Standard accessories include test leads (TL-23a), instruction manual and protective case. 2617
